I-78 Underclearances (Accelerated Bridge Construction)

Berks County, PA

This project involves the replacement of three, 3-span prestressed concrete box beam structures over SR 0078 at the SR 0183, SR 0419 and Midway Road interchanges to increase the minimum vertical clearance to 16′-6″. Also included was the reconstruction of the approach roadway and ramps at the interchanges. All three new structures are approximately 125′ single-span prestressed concrete PA-bulb tee beam bridges with cantilever abutments and wingwalls supported on shallow foundations. The new structures include the use of Accelerated Bridge Construction techniques utilizing an all precast concrete approach including deck panels. The overall construction duration is 45 days for SR 0183 and 60 days for SR 0419 and Midway Road making these some of the most aggressive complete interchange reconstruction projects in the Commonwealth.
