Children’s Hospital of Pittsburgh of UPMC, one of the nation’s premier pediatric hospitals, recently relocated to a new $590,000,000 state-of-the-art facility in the City of Pittsburgh’s Lawrenceville neighborhood. However, due to the dense urban location, a park-and-ride program for employees was needed in the form of a 1,450 space off-site parking facility with direct shuttle service to the Hospital. Oxford Development Company in conjunction with the University of Pittsburgh Medical Center (UPMC) retained TA to provide roadway design, traffic signal design and traffic engineering services for improvements associated with the development of a large off-campus employee parking lot as well as to assist with the evaluation of the functionality and overall design concept of the parking facility. The park-and-ride lot is situated between the City roadways of 55th Street and 57th Street and required considerable access and roadway improvements to accommodate the facility. New traffic signals were necessary along Butler Street (S.R. 2122) at 55th Street and 57th Street and 57th Street required complete re-design and re-construction for over 425 linear feet. The reconstruction of 57th Street included numerous design challenges including an active at-grade rail crossing, access to an existing public park with off-street parking, and maintaining existing commercial loading and access including a cold storage freight depot and a major fuel depot. TA also completed stormwater drainage upgrades working with the Pittsburgh Water and Sewer Authority (PWSA) and coordinated with the City to design sidewalks and ADA accessible ramps including a loading apron with rolled curbing along one side of the street to maintain existing commercial loading areas. A new traffic signal for the 57th Street / Butler Street (S.R. 2122) intersection was also designed. TA was also retained to complete a detailed traffic impact analysis for the facility and a functional review including operation and circulation and coordinated the project with City of Pittsburgh agencies.
