Traffic Engineering, Intersection Design, and Construction Consultation.

The project, which was a partnership between the Municipality of Bethel Park and PennDOT Engineering District 11-0, included adding turn lanes to each leg of one of the most congested intersections in the South Hills of Pittsburgh, and making select geometric (alignment) improvements to improve safety.  TA worked in conjunction with both PennDOT and the Municipality to “right-size” this project, using smart transportation principles.  Work also included: preparing NEPA environmental documentation (CE), conducting public involvement/consensus building activities, and supervision of subconsultants for geotechnical analysis and design of retaining structures.

A major challenge for this project was construction staging and maintenance and protection of traffic, as over 34,000 vehicles travel this intersection daily.
