The SR 0078, Section 12M, project involves the reconstruction of an eight mile section of Interstate 78 in Berks County. The western limit is located adjacent to the Maiden Creek Bridge near the Lenhartsville Interchange. The eastern project limit is located just past the Lehigh County Line in Weisenberg Township.
SR 0078 is a divided four lane interstate with an ADT of 48,417 and 35% truck traffic. A new truck climbing lane will be added in both directions. Six existing at grade structures will be replaced, three existing culverts will be widened, and four new retaining walls and four new noise barriers will be constructed. Several adjacent township roads will be reconstructed and the mainline work will be staged to maintain two eastbound and two westbound lanes of traffic on the interstate for the duration of construction.

PCS performed the overall project management as well as the design of the truck climbing lanes, bituminous and concrete pavements, retaining walls, structures, highway, drainage, and storm water management facilities. PCS also provided topographic survey and development of base mapping.
