Design and analysis
Vollmer designing three replacement bridges in Pennsylvania
Vollmer Associates has been selected by the Pennsylvania Department of Transportation to design three replacement bridges in rural Bucks County. The three existing bridges include: SR 4091, Kellers Church Road over Deep Run - a narrow one lane three span bridge with a timber and asphalt deck supported by stone masonry abutments and piers; SR 4023, Deep Run Road over Deep Run - a narrow two lane, three span stone masonry arch bridge. This bridge is unique because of its arch barrel layout and overall total length; SR 4091, Kellers Church Road over Cabin Run - a narrow two lane timber bridge with a timber and asphalt deck supported by stone masonry abutments. Vollmer's scope of work includes all phases of preliminary design, final design and construction consultation. Superstructure types currently being considered for the new bridges are prestressed concrete and precast concrete arch systems. Final design is scheduled for completion towards the end of 2003 with construction to begin in early 2004.
