Muddy Branch Bridge

SAI, a Mead & Hunt Company, is designing the foundations, substructure and superstructure of a new 3-span CCT bridge.  This proposed bridge will carry the CCT over the Muddy Branch along the southern edge of the existing Great Seneca Highway Bridge over the Muddy Branch and be designed to blend in with the existing structure. The existing bridge that carries Great Seneca Highway over Muddy Branch was constructed in the late 1980s by Montgomery County.

 

Retaining Walls
