Project:
West Busway Section AB6C
Corliss Flyover

Architect:
Michael Baker, Jr.

Owner:
Port Authority of Allegheny County

Mosites Construction Company was selected to construct the Corliss Flyover project to complete the West Busway from Pittsburgh to Carnegie.

Major components of the project included:

• Bridge - 464 feet, 3-Spans, Over Corliss Tunnel and Norfolk Railroad
• Three Concrete Cantilever Retaining Walls
• Soldier Pile Wall
• Precast Modular Wall
• Tree wells along Carson Street

This project was wedged in a small parcel of land that connected the West Busway with Carson Street. The bridge has both vertical and horizontal curves and provides a breathtaking view of Pittsburgh as you descend to Carson Street while "flying over" the Corliss Tunnel and Norfolk and Southern Railway.
