Penn Avenue, Pittsburgh, PA

L.R. Kimball was selected by the City of Pittsburgh, Department of Public Works, Bureau of Transportation and Engineering to complete the Penn Avenue Corridor Phasing Plan.  This plan was formulated to advise the City in programming and advancing transportation improvements along Penn Avenue given the corridor’s needs, community priorities, and available funding.   As part of the Phasing Plan, L.R. Kimball prepared a traffic study which examined existing and future traffic conditions at 31 intersections within the study area.    Projected volumes from Southwestern Pennsylvania Commission were used to perform capacity and queuing analyses with Synchro Traffic Signal Coordination Software to determine future intersection improvement needs along the corridor.  Based on the findings of the Phasing Plan, L.R. Kimball conducted Preliminary Engineering and Final Design for the Reconstruction Phase I Project.

The scope of work for the reconstruction project included total pavement reconstruction (including the curbs and sidewalks) new ADA curb ramps and detectable warning strips, utility relocations, drainage updates, new signing and pavement markings, new bus shelters, bicycle racks, street furniture and waste receptacles, new street lighting, streetscaping elements, new traffic signals, and safety improvements at the intersections.  This section was coordinated with work that was scheduled to upgrade existing intersections at 34th Street and Main Street.  The work included the limits of Phase I from the intersection of Penn Avenue and Mathilda Street to the intersection of Penn Avenue and Evaline Street.  This section included five (5) total intersections, three (3) of which were signalized including the intersections of Penn Avenue at Mathilda Street, Millvale Avenue, and Evaline Street.

There were numerous features incorporated into this project to enhance pedestrian and green infrastructure.  Several of these features include the use of bump outs at each of the intersections along Penn Avenue, high efficiency lighting, and the use of tree pits. Bump outs were used as a traffic calming measure and to create a pedestrian friendly environment along the avenue.  Metal halide lights were incorporated into the plan because of long service life, low maintenance, and efficient energy use.  Tree pits were utilized to capture stormwater from both roof tops and Penn Avenue and to provide biofiltration and decrease peak run off.
