Innovative mass concrete structure to transform bridge from historic to modern
Mosites Construction Heavy Division worked closely with the City of Pittsburgh to construct a project that both implemented modern design, while preserving the historic heritage of the bridge and its connection to Schenley Park. Mosites worked within tight timeframes over weekend closures of 376 East to demolish the existing structure, and erect the new steel arch structure. The project featured innovative mass concrete substructure elements requiring precise construction to ensure the fabricated steel structure could be slotted into place properly. Greenfield Bridge Reconstruction received the 2017 ABCD Award for Outstanding New Major Bridge from the Association for Bridge Construction & Design as well as the Transportation Project of the Year from the Engineers’ Society of Western Pennsylvania.
