Description

This project provides for the replacement of the existing Gold Mine Road Bridge over Hawlings River and the construction of 8'-0 bike path from James Creek Court to New Hampshire Avenue. The existing bridge, built in 1958, is a one (1) span 30' steel beam with an asphalt filled corrugated metal deck structure carrying a 15'-8" clear roadway with W-beam guardrail on each side, for a total deck width of 16'-7". The proposed replacement bridge includes a one (1) span 53' prestressed concrete slab beam structure with a 33'-0" clear roadway width. The project includes 250-feet of approach roadway work at each end of the bridge that consists of widening and raising the roadway profile by 5' at the bridge. The new bridge will carry two lanes of traffic, improve sight distances at the bridge, raise the bridge elevation to reduce flooding at the roadway, carry all legal vehicles, and provide pedestrian facilities across the river. The bridge will be closed for four months in the summer and fall of 2015.

Location

James Creek Court, Brookeville MD

Estimated Schedule

The design of the project is expected to finish in the summer of 2014. The construction is scheduled to start in fall 2014 and be completed in the fall of 2015.

Justification 

The proposed replacement work is necessary to provide a safe roadway condition for the traveling public. The 2009 bridge inspection revealed that the concrete abutments and wing walls are in fair condition and the bridge has a weight restriction which is controlled by the undersized steel beams. The bridge is currently on a 12-month inspection cycle to allow some school buses to exceed the inventory rating values of the beams. The bridge is functionally obsolete, carries two lanes of traffic on a single lane bridge with no sidewalks and has inadequate sight distance approaching the bridge. The bridge is closed two to three times a year due to flooding of the Hawlings River.
