McMahon, as lead consultant for this $1.0 million dollar TAP funded project, was responsible for the design of approximately 2,100 linear feet of sidewalk, bike lanes, five raised crosswalks, twenty-two ADA compliant curb ramps, landscaped berm, and ADA compliant driveway crossings. The purpose of this project was to provide traffic calming and a safe connection for bicyclists and pedestrians along the East Central Avenue to link residential areas with key destinations, including the current Paoli Train Station, Friendship Park, the Paoli Business District, and future extension of the Chester Valley Trail. This connection supports regional mobility by providing access to regional transit services and the regional trail system, which is known locally as The Circuit.

McMahon developed the initial improvement concept for East Central Avenue as part of the Paoli Roadway Improvements Feasibility Study. As a result of the study and successful applications, the Township was awarded a statewide TAP grant for the project. McMahon led the design and permitting process for the project, which included environmental studies/clearance (CEE Document), public involvement, right‐of‐way acquisition (temporary construction easements), utility coordination, preliminary engineering and final design, storm water design, preparation of Plans, Specifications and Estimate (PS&E) package. The project was submitted and advertised for construction through PennDOT’s Engineering & Construction Management System (ECMS). Construction was complete in the Summer of 2017.
