PROJECT DESCRIPTION

The Orting Emergency Evacuation Bridge project will construct a new elevated pedestrian bridge across SR 162. The bridge provides a single 112-foot main span across SR 162. The main span consists of two rectangular precast prestressed concrete girders with a 16-foot wide cast-in-place concrete deck between girders. The main span is supported on enclosed concrete walled piers which provide a 16-foot square landing for approach stairs and ramps. The west approaches include concrete stairs extending north and south of the west pier landing (Pier 1) parallel to SR 162. A 275-foot 5-foot wide ramp extends north from the Pier 1 landing. The ramp consists of a 145-foot elevated portion on concrete columns, with the remaining section transitioning to a walled section as the ramp profile descends to match existing grade. The east pier landing (Pier 2) includes concrete stairs extending along the main span alignments. Pier 2 also includes a 290-foot 5-foot wide ramp extending north from the Pier 2 landing. The ramp consists of a 143-foot elevated portion on concrete columns, with the remaining section transitioning to walled section as the ramp profile descends to match existing grade. Each main pier is supported on a shaft cap with four 5-foot diameter drilled shafts (8 total). All ramps and stairs are supported on 4-foot diameter drilled shafts (17 total). All drilled shafts are approximately 90 feet long. Other improvements include force main relocation prior to construction of the bridge, demolition of existing pedestrian pathways and construction of new pedestrian walkways.
