Flyer showing changes to Walnut Street's layout after repaving

How does a street change?

Walnut Street in Philadelphia recently went through some changes.

In late 2023, Walnut Street was repaved. The new Walnut Street was completely redesigned, with a new layout that included parking-protected bike lanes and shorter pedestrian crossings. If you drive, walk, bike, or roll around Walnut in West Philly, you might have questions about why the street changed. Here's more on the process.

Walnut Street

For some, the changes to Walnut were unexpected. 33rd to 63rd is a large stretch of street that many people travel on using different modes. Maybe those driving were caught off guard when they tried to merge but the new street layout didn't allow it. Change of any kind takes some adjusting, and usually comes with questions about why things had to change.

In the case of Walnut Street, the City decided to take advantage of repaving to implement a redesign, following Complete Streets principles (more on these in a moment) to increase safety on the corridor, with the nearby Chestnut Street serving as an example. Why was this street a candidate for a redesign?

Safety Concerns

This corridor has issues with traffic safety. Between 2018 and 2022, there were 331 reported crashes on Walnut Street between 33rd St and 63rd St in West Philadelphia. Though some crashes cause damage to property, some do have a higher cost. Data from the Pennsylvania Department of Transportation (PennDOT) shows that these crashes caused 214 injuries, with 15 people seriously injured, and three deaths. Serious injuries and fatal crashes are highlighted in red.

Vision Zero

Vision Zero Philadelpia is an iniative in the city working to improve traffic safety, with the goal of zero traffic deaths. To reach this goal, Vision Zero works with the City on safety improvement projects, much like the repavement project on Walnut Street.

To understand where in the city to focus traffic safety efforts, the City and Vision Zero used crash data to create the High Injury Network. As it turns out, 80% of traffic deaths and serious injuries happen on just 12% of Philadelphia streets. The High Injury Network shows us where these streets are.

A portion of Walnut Street from 49th to 63rd is part of the network.

What do we do?

Creating safer streets is an effort that involves planning, policy, and community engagement.

Transportation planners help design and implement changes that affect how we move around. To make those changes, they need the support of governments to support the implementation of plans through things like funding and permits. Community engagement is a vital part of this equation, as it's extremely important to involve community members in decision-making processes. Steps are being taken to make each step of this process more accessible to community members and improve equity in planning projects.

The Planners

A description from the Delaware Valley Regional Planning Commission's Complete Streets Resurfacing web page offers an overview of who is behind this project.

"This effort is being coordinated between the Delaware Valley Regional Planning Commission (DVRPC), PennDOT District 6, and the City of Philadelphia with the goal of identifying roads that are good candidates for complete streets facilities. Additionally, DVRPC assists the City of Philadelphia with an iterative design process that uses capacity analysis to assess the traffic impacts of proposed complete streets investments."

As we saw, PennDOT oversees and handles many transportation operations throughout the state, including collecting data like the crash data used for this project. DVRPC is a metropolitan planning organization, who helps governments in the Philadelphia region with planning projects through collaboration, research, and funding programs. For this project, they did an analysis of traffic to see if there would be consequences to any of the proposed Complete Streets designs. The City office involved is OTIS, the Office of Transportation and Infrastructure Systems . They are part of many planning projects in the City, and work closely with Vision Zero projects and Complete Streets.

Complete Streets

The City of Philadelphia's Complete Streets web page defines Complete Streets: "Complete Streets are safe, comfortable, and convenient. They are designed and operated to ensure safe access for all users, including pedestrians, bicyclists, motorists, and transit riders, regardless of age and physical ability."

A canvas for a Complete Street

The image of the intersection of Walnut and 42nd Streets in September 2023 shows why repaving was needed and that there was an opportunity to remake the street. Lack of street lines makes for confused drivers and aggressive drivers, and the bike lane was right next to the cars. Space for pedestrians crossing the street was also unclear, and we can see that a car waiting for a red light is stopped in the crosswalk.

Complete Streets principles say that to make this street safer, we should prioritize pedestrians and implement design that prevents serious crashes from happening.

The redesign

The image of the intersection of Walnut and 42nd Streets in June 2024, after repaving, is much different.

All street markings are clearly outlined on Walnut Street. Driving lanes were altered to be slightly more narrow, and parking lanes are right next to the driving lane instead of on the other side of the bike lane. The bike lane is now next to the side walk, with the parked cars serving as a form of protection from moving traffic on the street. Pedestrian crosswalks are wider and shorter due to the new parking lane, giving pedestrians more room while reducing the distance that they have to cross in front of traffic.
