Demolition, site work, paving and new construction of a bridge / tunnel in Mount Vernon, Indiana. Completed plans call for the demolition of a bridge / tunnel; for site work for a bridge / tunnel; for the construction of a bridge / tunnel; and for paving for a bridge / tunnel.

The project is located at Posey County Bridge No. 351, which carries Mulberry Street over CSX Railroad, at a point approximately 0.06 mile south of Grant Street in the City of Mount Vernon, Indiana. Under the preferred alternative, the proposed project would involve replacing Bridge No. 351 and construct a three-span continuous composite structure with an increased vertical clearance that meets the minimum bridges over railways requirement of 23-feet. 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 proposed typical section of the bridge would consist of two 10-foot-wide travel lanes (one northbound, one southbound) bordered by minimum 2-foot-wide paved shoulders, and 1-foot-4-inch-wide concrete railings. Additionally, a 6-foot-7-inch wide sidewalk would be constructed on the east side of the bridge between the shoulder and railing. The new bridge would have an out-to-out width of 34 feet 3 inches and a clear roadway width of approximately 24 feet 8 inches. It is anticipated that the proposed project would require the acquisition of greater than 0.50 acre of permanent right-of-way.
