More Cities are Razing Urban Highways

Removal of aging highways is a strategy some cities are using to try and boost their downtown districts – Christian Science Monitor

By Jeremy Kutner, Correspondent / March 2, 2011
New Haven, Conn. In New Haven, Conn., a mistake of the past – one that displaced hundreds, razed a neighborhood, and physically divided a city – is finally set to be rectified: A highway is going to be demolished.

Some people in New Haven have been waiting to see this for 40 years, ever since it became clear that a modern roadway slicing through the heart of downtown would not bring the hoped-for suburban shoppers and revitalization. That waiting list is long, it turns out, as cities across the United States look to erase some of the damage from urban highway construction of the 1950s and ’60s – tearing up or replacing the roadways and attempting to restitch bulldozed neighborhoods. ….

Making Streets Behave

New York City has issued its first street design manual, in an effort to make streets more environmentally friendly, and more amenable to bicyclists and pedestrians.  Urban planners see the document as a blueprint for designing the infrastructure for a 21st century city – one that thinks about streets as “…not just thoroughfares for cars, but as public spaces incorporating safety, aesthetics, environmental and community concerns.”  The guidelines help developers, both public and private, know what is expected of them throughout the five boroughs.

Here is what the manual says about itself:  The Manual builds on the experience of innovation in street design, materials and lighting that has developed around the world, emphasizing a balanced approach that gives equal weight to transportation, community and environmental goals. It is designed to be a flexible document that will change and grow, incorporating new treatments as appropriate after testing. The use and continued development of the Street Design Manual will assure that New York City remains a leading innovator in the public realm as it becomes a greater, greener city.

Stent (or Dagger?) in the Heart of Town: Urban Freeways in Syracuse, 1944-1967

The 1961 Decisions in Syracuse, by SU political scientists Guthrie Birkhead, Roscoe Martin, and others, explored a series of case studies of metropolitan action in Syracuse in the Post–World War II era. The study focused on public decision-making and the relative influence of various interest groups in the power structure at a time of emerging demographic change and suburbanization.  The case studies are fascinating glimpses at how important metropolitan issues, from sewage treatment and water district  to government reorganization and real estate development were approached in a regional context.

Although it occurred in the same time period, the I-81 construction was not a subject of the book. Creation of the highway system in and around Syracuse was much less a local, or metropolitan, process than a process in which federal and state plans, and dollars, determined transportation developments.  The recent study, Stent (or Dagger?) in the Heart of Town: Urban Freeways in Syracuse, 1944-1967, published in the May 2009 issue of the Journal of Planning History, takes a look at decision-making on the urban freeways in Syracuse.

Author Joseph F. C. Di Mento, a professor of Law and of Planning Policy and Design at the University of California Irvine, concludes that the timing of transportation decisions in Syracuse was important.  Before the evolution of environmental law, and at a time when the urban renewal goals of “slum clearance” and redevelopment converged with the funding opportunities of the federal highway fund, the fiscally conservative city administration deferred to state highway plans.  A relatively weak city planning function and a “strong engineering-driven state highway bureaucracy and gubernatorial positions” influencing choices Syracuse made, “ …led to an outcome different from what city fathers and officials had envisioned…”.

The approaching need to reconstruct parts of the freeway through the city gives Syracuse an opportunity to develop a new vision for the community.

Building Infrastructure-Building Experience

This week’s columns by Neal Peirce and Alex Marshall focus on the promise of high speed rail as the “New Deal” for transportation.  “My high-speed rail proposal,” President Obama is quoted as saying, “will lead to innovations that change the way we travel in America. We must start developing clean, energy-efficient transportation that will define our regions for centuries to come.”

Certainly, the costs of the projects will be challenging, but more than that, “America’s become tortuously slow, way behind world standards, in building any kind of infrastructure,” according to Peirce. “Some states spend years just adding HOV or exclusive bus lanes to existing highways.”

Marshall reports that former Massachusetts governor Michael Dukakis, a big rail booster, says that over-budget, drawn-out infrastructure construction has become the norm.  State and local governments tolerate huge multi-year delays.  “The cure, says Dukakis is competence: to learn to undertake great projects again, and to value quality government.”

The I-81 corridor project, whatever form it takes, will be of a scale not experienced in Syracuse since the viaducts were originally planned and constructed.  Our elected officials and transportation authorities will have to exhibit the scale of leadership and guidance that a project of its magnitude requires.

John O. Norquist, Change Agent

April 19, 2009

One of the panelists at this week’s annual meeting of the Metropolitan Development Association is John O. Norquist, a former lathe operator and community organizer who later became a state legislator and then mayor.  As mayor of Milwaukee from 1988-2004, Norquist oversaw a revision of the city’s zoning code and reoriented development around walkable streets and public amenities such as the city’s 3.1-mile Riverwalk.   He also earned widespread recognition for championing the removal of a .8 mile stretch of the elevated Park East freeway, clearing the way for an anticipated $250 million in infill development in the heart of Milwaukee.

As current president and CEO of the Congress for the New Urbanism, a national organization promoting walkable, neighborhood-based development as an alternative to sprawl, Norquist continues the highway to boulevard campaign, believing that urban boulevards offer an attractive option for cities with aging highway infrastructure.  Cities like Portland, San Francisco, New York, and Milwaukee have found that removal of outdated elevated freeways – major physical and psychological barriers – stimulates investment and new development in the surrounding property.

A close examination of the Milwaukee experience is instructive for Central New York as we plan for the replacement of the deteriorated I-81 viaduct through Syracuse.

The Onondaga Citizens League “Rethinking I-81” Study Committee has studied the history and the physical condition of the I-81 corridor, reviewed access issues, and examined cases of freeway removals in American cities. The study report, including the committee’s findings and recommendations, will be issued later this spring. In considering the future of I-81 in Syracuse, the Committee found several factors concerning the elevated portion of I-81 important to an understanding of the project.

• Due to age and structural deterioration, the elevated portion of I-81 through Syracuse must be replaced, not simply repaired, in the near future. In its current configuration, the I-81 viaduct and ramps do not meet current design standards. The reconstruction project, whatever form it takes, will require a huge amount of public funds and a permanent reconfiguration of some traffic routes.

In its entire length, I-81 bypasses every downtown except for that of Syracuse. Syracuse is the only city in the entire 855 miles of the I-81 corridor where the highway bisects a city. Moving maximum volumes of cars as fast as possible is fine between cities, but is not good within cities, because the systems that make speed possible are bad for local businesses, neighborhoods, and economic development.

• Downtown Syracuse is the only place on I-81 where the speed limit is reduced to 45 mph. An interstate highway that serves a high proportion of local traffic, as well as regional traffic, does not serve either optimally.

• The SMTC University Hill Transportation Study (OCL blog post #4) concluded that tearing down I-81 in the Almond Street Corridor and rerouting through traffic might be feasible. The consultants recommended an in-depth study of an urban boulevard in lieu of the I-81 viaduct, with through traffic rerouted to I-481. The report predicted that a boulevard option would improve accessibility for commuters, visitors, and emergency vehicles, create better connections between downtown and University Hill, increase economic development opportunities, and improve air quality in the area.

• The I-81 corridor is a significant barrier between downtown and the economic engines on the Hill, devaluing the commercial and residential development potential of property all along the corridor. SUNY Upstate Medical University and Syracuse University are the area’s two largest employers. These growing institutions, and others in the area, need room to develop and expand and can generate residential, retail, commercial and additional institutional development. They grow best when they grow organically and are well connected not only by car and public transit, but also by foot and bicycle, and in terms of visual quality.

• The I-81 viaducts were recently put under a special on-going emergency repair contract by the New York State Department of Transportation, signaling that the aging infrastructure will require an increasing amount of unscheduled repair work. As much as any solution will cost, the financial cost, and safety considerations, of not making a timely decision could be even higher.

When we think about engineering solutions to traffic problems, it’s useful to keep in mind that human behavior is a key variable in the equation.  Drivers adjust their behavior to the situations presented to them.  When the 1989 Loma Prieta earthquake damaged San Francisco’s Central Freeway, the destroyed northern portion of the viaduct was demolished, while the southern portion, running above Octavia Street, remained.   A city task force recommended replacing the elevated freeway with a surface boulevard that would make it easier for local traffic to access the neighborhood, but the state department of transportation decided to rebuild the deck.  When the reconstruction project began, the predicted gridlock failed to materialize; local streets handled the traffic without any major problems. With this evidence that the street grid could handle most of the traffic when the freeway was shut down, neighborhood residents ultimately were able to force a referendum that ended in removal of most of the freeway and the creation of Octavia Boulevard.

What would happen if sections of Interstate 81 through Syracuse were shut down for an extended period?  We actually have some experiences that give us an indication of how Central New Yorkers would react to a planned closure of a main route to downtown and the University Hill area.  Ten years ago, construction closed the northbound lanes of I-81 from the Brighton Avenue exit to the Harrison Street on-ramp for about three months.  When that project was complete, the southbound lanes were closed from Interstate 690 to Calthrop Avenue.  It was the first major closure since I-81 north was shut down for eight months in 1988 to repair badly deteriorated bridge decks.

For months before the shutdown, the State Department of Transportation conducted a massive campaign to inform city officials, businesses, and residents about the project and alternative routes.  The newspapers were full of warnings for weeks in advance of the construction for the estimated 30,000 drivers a day who took I-81 north through Syracuse.  In addition, plans including street sign and traffic signal changes, additional traffic police, and even a free OnTrack train between Jamesville and Armory Square were put in place to keep traffic moving.

 “Where’s the Rush?  First Day of I-81 Detour Goes Smoothly” was the headline on the May 27, 1999 Post-Standard story.    At the peak of the first rush hour affected by the northbound shutdown, “…there was virtually no traffic on the detour route where state transportation officials feared a major backup.”  Commuters found their own quickest secondary routes to use, diverting cars from the detour routes and allowing traffic to flow smoothly.

Commuters leaving downtown during the afternoon rush hour had a more difficult time after DOT shut down the I-81 connector to I-690, and the Harrison Street on-ramp was reduced to one lane.  As drivers avoided the on-ramp and learned to use alternate routes to access I-690 east, traffic eased over the following days, though backups at intersections still occurred, as drivers, particularly those heading north, headed to the Harrison Street ramp.  Deck repairs north of downtown closed lanes and slowed traffic in that area, but even those slowdowns added less than five minutes to total commute time, the DOT spokesman was quoted as saying.

The OnTrack commuter train, which offered free rides between Jamesville and Armory Square during the construction, averaged only 35 riders a day, because, it was assumed, the gridlock that was expected to cause severe traffic delays never occurred.  “Motorists and police feared gridlock would seize the city when a 2 ½ mile stretch of I-81 northbound lanes were closed in May for repairs.  But the back-ups were minor.” (The Post-Standard, August 19, 1999 pg. A1).

When DOT closed down I-81 south, including the connectors from I-690 east and west, affecting nearly 35,000 daily travelers, DOT officials were more optimistic.  In fact, the closure of I-81 south to replace expansion joints and make other repairs, generated almost no news, and apparently only minor traffic tie-ups.  Commuters seemingly adjusted their schedules or their routes through the 2 ½ months of repairs. As then assistant DOT regional director George Angeloro said during the northbound shutdown: “Traffic is like water. It seeks its own levels.”  

A temporary shutdown can give us a partial indication of what might happen if the highway were replaced with an alternative roadway.  As in other cities that have permanently eliminated a freeway, improvements to the surrounding street grid, as well as pedestrian, bicycle, and transit considerations, would be part of the mobility plan.

The future of an earthquake-damaged viaduct remains undecided

Alaskan Way Viaduct – Source: People’s Waterfront Coalition

How do you replace an unsafe elevated highway when no one likes the alternatives? That problem has been plaguing the city of Seattle. In 2001 an earthquake damaged the Alaskan Way Viaduct, a 1.4 mile section of Highway 99 that divides Seattle’s downtown core from its waterfront. What seemed an opportunity to redefine the city’s transportation system and to link two vital neighborhoods that are divided by the viaduct became mired in divisive politics.  Conflict led to a public referendum in March 2007, giving Seattle citizens a choice between rebuilding an elevated highway and constructing an underground tunnel. Residents voted “no” to both.

Ranked #1 on the Congress for the New Urbanism’s “Freeways Without Futures” list, the Alaskan Way Viaduct is a major regional route into Seattle, carrying about 105,000 vehicles a day.  The highway was built on fill, so the underground piles have become a problem, and the seawall that hold up the highway is also deteriorating.

After last year’s unproductive referendum, the Seattle City Council called for the Seattle DOT to develop an Urban Mobility Plan – a systems approach, including surface road, transit and other improvements – to replace the highway capacity.  Tom Brennan, a native Central New Yorker, is a Portland, Oregon-based transportation consultant, whose firm Nelson/Nygaard, is currently working with the City of Seattle.  N/N is developing the Urban Mobility Plan, part of the Center City Seattle Access Strategy – strategic transit service and surface street grid improvements and demand management strategies that together would absorb the current traffic on the viaduct.

Proposed Surface Alternative – Source: People’s Waterfront Coalition

In a presentation to the Rethinking I-81 Study Committee, Brennan explained that even before the earthquake damaged the elevated freeway, environmental issues, energy concerns, and growth projections were forcing Seattle to take a comprehensive systems approach to moving people and goods to and through downtown. The Vice-Chair of the City Council’s Transportation committee put it this way: “The replacement of the viaduct is a fantastic opportunity to begin the creation of a 21st century transportation system. The car can no longer rule all our decisions. There’s got to be a better way.”

In early 2008, the governor of Washington State declared that the damaged viaduct will be torn down in 2012, no matter how much or how little has been done to create an alternative solution. The city, county and state are again looking at the alternatives, agreeing that “the core elements of any solution must address issues such as vigorous public transit, freight mobility, business disruption, urban design, job creation, the preservation of our marine economy and the future of Seattle’s central waterfront” in addition to the fundamental safety, capacity and financial responsibility criteria. In June 2008, the State DOT released eight proposals for a new roadway, including boulevard, elevated viaduct, underground tunnel and cut-and-cover tunnel alternatives. A retrofit of the existing viaduct is not an option. The proposals were presented to stakeholders on September 25.  A decision is due at the end of the year. According to the Seattle Times, however, costs could eliminate some plans.  The State originally had a $2.8 billion budget, but has spent nearly half of that on work to stabilize the existing viaduct.

Buffalo’s Outer Harbor Expressway

Post #6

Earlier this month Buffalo Niagara Riverkeeper and three other groups filed motions in an earlier lawsuit in US District Court in Buffalo to require the New York State Department of Transportation to modify its construction plan for Route 5 between the Outer Harbor and downtown Buffalo.  Riverkeeper and its allies argue that the at-grade boulevard plan will not cost more money in the long run, will improve access to the water, and will free up 77 acres for waterfront use and development, while adding only three minutes to the commute.

Riverkeeper is one of many local groups that have been trying to stop the embanked Route 5 in favor of the boulevard in order to increase public access to Lake Erie and take advantage of the lakefront development potential.  The Congress for the New Urbanism, a national organization promoting highway-to-boulevard alternatives as part of walkable, neighborhood-based development, has also taken an interest in the Buffalo project.  CNU’s John Norquist was in Buffalo last week, reiterating the benefits of the boulevard approach.

According to the DOT website, its “… Buffalo Outer Harbor Project was developed with the participation and cooperation of many community and civic leaders, civic organizations, community members and professional organizations.”  However, the boulevard alternative, which State DOT also concluded to be “feasible” and which  is preferred by many civic leaders and members of the community, was not selected.

The preferred DOT approach and a variation of the DOT boulevard alternative were evaluated by a traffic engineer for the consulting firm Smart Mobility, Inc., who concluded there were substantially greater development opportunities with the multiway boulevard.  The Smart Mobility assessment of the DOT-preferred route found no explanation for the NYSDOT decision to keep the elevated Route 5.

Opponents of the embanked Route 5 point out that it needlessly maintains Route 5 as a noisy, high-speed, limited-access highway for just several thousand feet before it meets at-grade traffic lights anyway.  The elevated Route 5 limits the number of possible access points to the Outer Harbor and opponents say it compromises the potential for economic development on the Lakefront.

In addition, what is at issue is not just the 77 acres and waterfront land in the Outer Harbor area, but also the future of the Skyway Bridge leading to downtown Buffalo.  The reconstruction of the elevated Route 5 would seem to guarantee that the elevated Skyway Bridge will stay elevated when it is time to consider its future, in spite of long-range redevelopment plans that would replace it with a street-level crossing.
