Document Description
The County of Los Angeles Department of Public Works is proposing to demolish the existing bridge structure, Little Tujunga Bridge over Pacoima Creek (proposed project), and construct a new bridge as a replacement at the same site. The proposed project site is located within unincorporated County of Los Angeles land surrounded by the Angeles National Forest, approximately 9 miles north of SR 210 (Foothill Freeway) from the Osborne Street exit. The existing A-frame Bridge constructed from timber piles would be replaced with a new single-span, pre-cast, pre-stressed concrete girder bridge structure that would have a width of 32 feet and span of 65 feet. The proposed new bridge would also have wing walls at all corners of the bridge. It is anticipated that approximately 100 feet of roadway reconstructor in both directions of the proposed new bridge would be required. The proposed project would include installation of CA Department of Transportation type 25 concrete barriers with tubular handrails on both sides of the proposed new bridge and metal beam guardrails at the approach corners. The proposed project would involve widening the existing lanes to meet current design standards. The proposed new bridge foundation would be composed of pile footing using cast-in-steel shell. Pre-stressed concrete I-girders with a cast-in-place concrete deck would be installed for the bridge superstructure. The proposed concrete superstructure would be approximately 44 inches deep, with a span on approximately 65 feet to maintain and slightly improve the hydraulic capacity of the Pacoima Creek as it flows under the bridge.
