Pomona Avenue Bridge Replacement Project
The proposed project will replace the existing bridge along a similar alignment as the existing structure. The new bridge will accommodate two 11-foot travel lanes, 5-foot shoulders and 5-foot sidewalks. The profile will be raised slightly to maintain the same bridge soffit elevation as the existing structure. The replacement bridge is anticipated to be a single-span, cast-in-place post-tensioned concrete slab, approximately 75 feet long. Construction of the bridge will involve excavation for and construction of concrete abutments, founded on cast-in-drilled-hole concrete piles. Other temporary work within the Little Chico Creek includes removal of the existing structure, falsework erection and removal, and installation of scour countermeasures at the abutments. Little Chico Creek is a seasonal creek and construction is anticipated to proceed when the creek is dry, thus a temporary water diversion system will not be required. Construction of the roadway approaches will involve the removal of existing pavement and placement of roadway fill material, aggregate base and hot mix asphalt pavement. New curb, gutter, and sidewalk will be constructed on the north and south side of the roadway and will connect with existing pedestrian facilities. During construction, Pomona Avenue will be closed to traffic and a detour route made available. Vehicular traffic would be able to cross Little Chico Creek on Walnut Street, just north of the project site. The maximum detour length is just over 1 mile. All construction staging will occur on the closed Pomona Avenue. Tree removal and removal of other vegetation along the creek will be necessary for the project.
