Replacement of Bridge No. M-PK24 Beach Drive over Silver Creek

The project provides for the replacement of the existing Beach Drive Bridge over Silver Creek. The existing bridge, built in 1964, consists of three steel plate arches. The bridge provides a 24’-0” wide clear roadway with a 7’-0” Rock Creek Trail on the north side and has two 1’-9” parapets. The proposed replacement bridge includes a single span prestressed concrete slab beam structure carrying a 22’-0” roadway and a 5’-4” shoulder on each side. This width will allow for the implementation of safe on-road bicycling, in accordance with the Master Plan. The Rock Creek Trail will be relocated to cross Silver Creek approximately 90 feet north of the proposed Beach Drive Bridge, this will improve safety by separating the pedestrian and light-use bicycle traffic from the vehicular traffic. The project includes approach roadway work at each end of the bridge as necessary to tie-in to the existing roadway. The bridge and road will be closed to traffic during construction. In order to maintain pedestrian traffic on Rock Creek Trail during construction, the pedestrian bridge and its approaches will be constructed prior to the removal of the existing Beach Drive Bridge.
