Title

Compton Boulevard Bridge Over Compton Creek

Description

The proposed project would involve the demolition of the existing two-span, steel-girder Compton Boulevard Bridge with a new two-span, pre-cast concrete bridge. The proposed project would address existing bridge deficiencies, enhance vehicular safety on the bridge and improve transportation efficiency by enabling larger trucks to utilize the bridge. The existing steel girder bridge and middle pier have been determined to be structurally deficient due to extensive cracking and delamination of the bridge deck. The new bridge soffit (underside) would be raised approximately one foot higher than the existing bridge. The new bridge would include a new pier with a new pre-cast, pre-stressed, concrete box beam structure supported by pile foundations, and new channel walls/abutments. The new abutments would be constructed approximately 15 feet behind the existing abutments, which would be protected in place with minimal modifications to provide clearance for the new bridge structure. Modification to the existing abutments that act as the channel walls would include removal of existing backwall down to the seat elevation to allow new bridge superstructure to span over the existing abutments. The existing channel walls outside of this limit will not be modified. Additionally, a new, sloping concrete pier nose would be constructed upstream from the bridge as part of the proposed project. In addition to the proposed bridge replacement, the proposed project would include reconstruction of the existing bicycle path, which runs adjacent to the north of the Compton Creek channel, as well as reconstruction of several sidewalk and driveway locations and the reconstruction of a new access road.
