Document Description
The existing Jack Creek Road Bridge at Paso Robles Creek is at the end of its service life. The existing bridge will be replaced with a new structurally sound bridge to improve public safety and improve access to the area. The new bridge will be constructed to meet current applicable American Association of State Highway and Transportation Officials (AASHTO) and Caltrans Criteria. The project includes removing the existing 11-span, 204-foot-long bridge and replacing it with a cast-in-place concrete box girder 2-span bridge approximately 225-feet-long and 28-feet-wide to accommodate two 10-foot-wide travel lanes, 2-foot-wide shoulders, and two concrete barrier rails with guard rail end treatments. Existing wood and steel bridge pilings and piers will be removed. The new single concrete bridge column will be approximately 4.5 feet in diameter with a seven-foot diameter pile. New concrete abutments will be supported by concrete piles and the embankment will be protected with rock slope protection. Additional construction activities include clearing and grubbing vegetation, stream diversion and dewatering, public utility relocation, stormwater treatments, installation of falsework, road approach work, and habitat mitigation. Construction access, material storage, and equipment/vehicle staging will occur within the designated County right-of-way and adjacent private land to the southeast or southwest to be secured under a Temporary Construction Easement. Construction would be mostly completed during the dry season (May through October) to take advantage of low flow conditions in the creek. Jack Creek Road at the bridge will be closed during construction and traffic will be detoured on Jack Creek Road to Vineyard Drive or SR-46.
