The previous bridge was a five-span, approximately 212′ 6″-long structure with a superstructure consisting of four cast-in-place concrete tee-beams carrying one lane of traffic in each direction.  The structure was in a horizontal curve, as well as a vertical curve and carried a 16″ waterline in the center bay, a main distribution line for Pulaski County.

The $4.4 million project included design of the approach roadway reconstruction of approximately 500-800 LF north of the bridge and 500-800 LF south of the bridge.  The scope of work focused on the first three major phases:  Phase I – Evaluation; Phase II – Scoping/PFI; Phase III – Public Hearing/Public Involvement.  The design scope took the project through design approval and followed VDOT’s Project Development Process.

Services for the project included a study to determine the feasibility of several replacement options for the previous structure.  This stretch of Route F047 is part of the U.S. Bike Route 76.  The bridge needed to be replaced utilizing phased construction to maintain service for the existing waterline.  The project included evaluation of a minimum of two schemes for replacement that encompassed closing the road with a full detour and various alternatives for phased construction due to the waterline.  The previous bridge location was maintained.  The study focused on replacement cost option and in general covered issues such as maintenance of traffic, constructability, durability, sustainability, and navigability of the waterway below the bridge.
