Posey County Bridge No. 351 Improvement Project
DES. NO. 2201662
Mount Vernon, Posey County, Indiana
PROJECT DESCRIPTION
The project is located at the Posey County Bridge No. 351, which carries Mulberry Street over CSX Railroad approximately 0.06 mile south of Grant Street in Mount Vernon, Posey County, Indiana. The project will replace existing bridge 351 and construct a three-span continous composite prestressed concrete box beam bridge on the same alignment, but with an increased vertical clearence of 23 feet that meets the minimum bridges over railways requirement. The vertical alignment of Mulberry Street would also be raised by a maximum of 6 feet in order to improve the sight distance for vehicles approaching the bridge. The typical section of the bridge will consist of two 10-foot-wide travel lanes (one northbound, one southbound) bordered by a 2-foot-8-inch-wide paved shoulder of the west side, a 2-foot-wide paved shoulder on the east side, and 1-foot 4-inch-wide concrete railings. Additionally, a 6-foot-7-inch-wide sidewalk will be constructed on the east side of the bridge between the shoulder and railing. The new bridge would have a total length of 109 feet, an out-to-out width of 34 feet, 3 inches, and a clear roadway width of approximately 24 feet, 8 inches.
