A Case For An Urban Expressway

The movement to eliminate urban freeways has been gathering steam and a number of high-profile supporters, and understandably so. It’s been demonstrated on numerous occasions that freeways and cities don’t play well together, or at least not as well as either freeway advocates or the municipal officials who welcomed their arrival in the 1950s anticipated. Next American City has showcased several examples where removing urban freeways has stimulated the revitalization of urban areas in places like San Francisco and Portland, and earlier this year it sponsored a forum, “Reimagining Urban Highways,” at the Academy of Natural Sciences of Drexel University in which a host of urban officials discussed the positive forces unleashed when urban freeways were removed.

There’s a powerful case to be made for this argument. Urban freeways disfigure large swaths of land, and high-speed car access to urban centers undercuts the ability of mass transit–a more density-friendly form of transportation–to serve them effectively. Society Hill residents fought furiously to have Interstate 95 buried through Center City in the 1960s, correctly seeing the proposed elevated highway as cutting the city off from its waterfront. More recently, Diana Lind, the editor of Next American City, spearheaded a dialogue about the complete removal of I-95 through forums like the one in February.

But just as enthusiasm for urban freeways was overdone, so may be enthusiasm for their removal. Unless we eliminate cars entirely–an unlikely proposition–there will need to be provisions to handle them, sometimes in large numbers, in our cities.

While I agree with Jane Jacobs that we should pursue “the attrition of cars by cities,” “attrition” falls well short of elimination. And furthermore, there are places where adding rather than removing a freeway makes an urban environment more pedestrian-friendly. To understand why, let’s go back to the future and up to the part of town I now call home.

The photo above shows Vine Street after it was widened to 10 lanes east of 15th Street in 1951. While the road is relatively free of traffic in this picture, it would not remain so for long: by the 1970s, it hummed with traffic most of the day, and crossing it on foot was at best an unpleasant experience.

Fast-forward to today, after Vine Street’s center lanes were buried in a trench that extended the Vine Street Expressway across Center City. Those buried lanes took most of the traffic with them, and now, pedestrians can cross Vine Street with relative ease and safety at all but the worst congested periods.

As with Vine Street, so with Roosevelt Boulevard, the central artery of Northeast Philadelphia. A 1950s reconstruction project reconfigured that street as well, turning it into a 12-lane, double-divided boulevard much like Vine Street downtown. The improvements also turned it into a near-expressway, and drivers have treated it as such ever since, to the detriment of anyone who tries to cross it.

The recent installation of pedestrian crosswalk signals at several points along the street indicates that the city understands the hazards of crossing the Boulevard. But the real path to eliminating the hazard lies in doing to the Boulevard what the state did with Vine Street in the 1990s.

Pedestrians can cross Oxford Circle without fear, for instance, because the inner lanes dip beneath it. Putting those lanes in a trench that runs the length of the street would not only make the existing pedestrian crossings safer, it would open up the possibility of even more places to cross, especially if the submerged inner lanes are covered with a cap. That cap, in turn, could either be landscaped, restoring the Boulevard to something like its original appearance, or–thanks again to the street’s width–it could support mid-rise, mixed-use development that could truly transform the Boulevard into a real Main Street for Northeast Philadelphia.

And as a bonus, that trench could also accommodate the one mass transit project just about everyone agrees needs to be built, a subway for the Northeast. Forget light rail: there is enough demand for transit in the Northeast to justify true rapid transit instead of a half-measure, and a recent cell phone poll conducted by the Philadelphia City Planning Commission demonstrated that if we built it, people would ride.

A Northeast Philadelphia extension of the Broad Street Line remains a key component of the Delaware Valley Regional Planning Commission’s Long-Range Vision for Transit, and the City Planning Commission’s poll helped shape the final form of the recently adopted Lower Northeast District Plan, where the poll results can be found. (Some argue that rapid transit lines in freeway medians still give the car pride of place and an advantage over transit. I suspect a driver stuck in rush-hour traffic on Chicago’s Dan Ryan Expressway while Chicago Transit Authority ‘L’ trains zip by would beg to differ.)

Of course, all this would cost serious money, and cost is what derailed the city’s last serious effort to make this vision a reality in 2003. But the benefits would be well worth the expenditure. All we need to do is put our reflexive antipathy to urban freeways aside. Vine Street showed that such roads can improve the urban environment for all if built right. In the Northeast, we have another chance to do that.

  1. Remember, however, that Vine Street’s center lanes were buried only years and years after narrow Vine Street was widened in the 1940s/50s. An entire city block wide (developed but decrepit) swath of the city was removed to widen Vine Street. I believe the boulevard was always planned to be as wide as it is now.

    • Indeed it was, Harry. But in its older configuration – a four-lane undivided road in the center, with very wide planted medians separating that road from the two two-lane-plus-parking side roads – it was less of a high-speed thoroughfare than it became after its 1950s reconstruction, and less intimidating for pedestrians to cross as a result.

      No matter what shape it takes, the Boulevard’s very width will make it impossible to cross completely in a single traffic signal cycle for most pedestrians. But with six of the current 12 lanes out of the way, crossing it will take less time still, for pedestrians won’t have to keep their wits about them the way they do now.

  2. 16. Trillion in debt..it ain’t happening now matter how good it is.. Perhaps if they opened up the redesign of the
    Boulevard to the public…. Like with the HIGHLINE and viaduct Greene… They would find out what the public
    Wants and what it can afford.. A subway is way to expensive , light rail maybe.. BUT a BRT line , like the
    Trams milenium in bogota… Just running down the center lanes ( separated bus lanes ) with dedicated bike lanes to the side maybe and a greenway type redisign….. That might work. And it might be affordable

    • Sometimes you have to pay for the right stuff. The Boulevard already has three bus routes that run along all or part of it, and one of them – the 14 – is packed at most times of the day, running articulated buses at close headways. The City Planning Commission has studied potential ridership, and that cell phone poll I referred to in this post backs up their studies: If there is anyplace in the city where nothing less than true rapid transit will do, it is here.

      Yes, it’s expensive. I acknowledged that above. What I propose here is exactly what the Planning Commission recommended the last time the city studied the issue in detail in 2003. This project would produce great benefits for the Northeast and the city as a whole for years to come. Since we know we already need this level of transit service, and since putting the inner lanes in a trench would make the Boulevard safer all around, why settle for half-measures simply because they cost less?
