The substructure of the existing bridge has cracking and weathering of the mortar in the joints of the stone masonry abutments. The top section of the retaining wall near the north abutment has broken away and is leaning outward horizontally. The width is only 18 feet between the barriers, which does not meet the AASHTO standard of 11-foot minimum lanes.
Dry Creek Road is designated as a "minor collector", and the existing bridge is an "Off-System" bridge, and thus the project is eligible for 88.53% HBP funding and 11.47% Toll Credits funding as the match for local funds. The proposed bridge structure would consist of an approximately 80-foot-long by 32-foot-wide single- span concrete slab bridge on pre-cast and pre-stressed concrete girders. The project also includes 900 feet of new roadway to remove two curves in Dry Creek Road. County staff anticipates that the contractor will build the project in four stages to minimize the disruption to traffic and this would require work in Dry Creek over two summers.
