Lawrence Ramsey VDOT, applicant is proposing to replace the structurally deficient Structure 9760 east bound along I-64 and west bound structure 9762 along I-64, the two existing I-64 E and W bridges, over Route 156, with one structure and increasing the vertical clearance from 14’6” to 16’6”, required by AASHTO LRFD Bridge Design Specifications. The increase in vertical clearance will be derived from a combination of roadway profile raise and optimizing replacement structure depth. Widening will occur to the inside. No changes to the horizontal alignment of I64 are proposed however, Route 156 will be brought up to standard to the termini of the merge/acceleration lanes. The interchange will be converted from a cloverleaf to a partial cloverleaf in an attempt to reduce the construction limits and impacts along Route 156, the ramps, and the loops of the interchange. Crashes along I-64 will be reduced by removing the weave.The project is located at Latitude: 37°31'52" Longitude: 77°20'29" FEMA FIRM number: FM51087C0165C Nearest Community: Sandston - Surrounding Land Use: Commercial, Urban mix Basin: unnamed tributary to Gillie Creek / James River Basin Sub-basin: 2C.
