The City of Pittsburgh’s Department of Mobility and Infrastructure (DOMI) is excited to announce that construction will begin for Phase 2 of the Allegheny Circle Two-Way Conversion Project on April 19, 2021. The project is expected to be completed by the end of 2021.

“Allegheny Circle” consists of four streets (North, East, South, and West Commons) in the Allegheny Center neighborhood that functioned for years as a 4-lane one-way ring road. Phase 1 of the project, completed in 2018, reduced the travel lanes from 4 to 2 and added a bi-directional cycle track on the inside of the circle and parking on the outside. Phase 2 of the project will finish the transformation of the circle from a vehicle-centric street to a neighborhood-scale, multi-modal, pedestrian friendly street.

The project will convert the street to two-way operations for vehicles, with one lane of traffic in each direction. The cycle track will be upgraded, and bicycle facilities will be extended to connect with existing facilities. The project will include upgrades to traffic signals, intersection modifications to improve safety for pedestrians and bicyclists, upgraded curb ramps, new pavement markings and signage, and other miscellaneous construction.

Construction will generally occur during the week, Monday through Friday, during daylight hours. One lane of traffic along N, S, E, and W Commons will be maintained throughout the construction project. Detours will be implemented over the course of the project for East Ohio Street, North and South Federal Street, Ridge Avenue, Sandusky Street and Stockton Avenue. Advance notice will be given prior to detours being put in place.

A section of Ridge Avenue and East Ohio Street at Allegheny Commons will be closed beginning April 19, 2021 until early July 2021 as part of the Allegheny Circle Phase 2 (City of Pittsburgh) project.

The detour routes are as follows:

  • East Ohio Street: Cedar Avenue to East North Avenue to North Federal Street
  • Ridge Avenue: Arch Street to West North Avenue to North Federal Street
