The Department of Mobility and Infrastructure (DOMI) is planning and designing a quick-build traffic calming project on S 18^th St as part of its 2025 suite of Vision Zero implementation projects. The City will identify and implement targeted safety improvements on S 18^th St between E Carson St and Monastery Ave to alleviate the safety issues that put this section of S 18^th St on the High Injury Network (HIN).

The draft corridor plan is viewable here as a series of images. It is also available for viewing or download in PDF form at the bottom of this page.

S 18th St sees a particularly high rate of angle, head-on, and sideswipe crashes, which have caused 37 injuries and one fatality in the period from 2019-2023. This project will improve safety for residents and visitors of S 18th St by implementing traffic calming designs which have been proven to reduce crash severity. Additionally, this project aims to improve access to bus stops and create the bike connection into South Hills neighborhoods called for in DOMI's Bike(+) Plan.

A public meeting was held at the South Side Market House on Tuesday, June 24th, 2025. At the meeting, the project team presented a project progress report and walked constituents through the newly released conceptual plan. The meeting had both in-person and digital attendance options, and feedback on the conceptual plan was collected via sticky note, Zoom chat, and verbal conversation.

What We Heard

• Mostly positive feelings about proposed traffic calming and the need to address speeding
• Residential parking needs at Mission Street bend
• General support for proposed climbing bike lane
• Requests for additional speed tables and crossings
• Concern about parking enforcement re: sidewalk parking
• Concern about vehicles entering sidewalks and hitting pedestrians and buildings
• Loading concerns from businesses along the corridor
• General support for proposed Monastery Ave and Pl one-ways

During March's Community Walkthrough, community representatives suggested connecting the S 18 ^th St steps to the S 18^th/Josephine intersection and its new signalized crossings of S 18 ^th St. By coordinating the ongoing steps rehabilitation project and the Critical Sidewalk Gaps program, DOMI identified an opportunity to rapidly construct this requested sidewalk segment. The sidewalk was completed in May/June 2025! Refer to the Critical Sidewalk Gap Program's Engage Page for further information.

On Monday 3/3/25 the project team held a walkthrough of the corridor with representatives from stakeholder groups. In attendance were representatives from South Side Smart Streets, the South Side Slopes Association, Pittsburgh Regional Transit, and City Council District 3, as well as staff from DOMI, the Office of the Mayor, and the Department of City Planning. Representatives from Hilltop Alliance, South Side Community Council, and South Side Community Action Network were also invited to participate.

On the walkthrough, we discussed issues including:

• speeding,
• pedestrian crossing safety,
• accessibility challenges posed by sidewalk parking,
• poor signage for upcoming curves and pedestrian crossings, and
• confusing intersection geometries with poor sightlines.
