Foothill Road Low Water Crossing Bridge Replacement

Project Description: The Foothill Low Water Crossing (LWC) Bridge Replacement Project is near Cuyama, California. It is located about two miles west of Highway 33 in Santa Barbara County.

The previous LWC experienced water over toping the roadway during seasonal rain events and created nuisance flows. At times of more significant, rain events, the flow depth at the crossing increases, limiting vehicle, bicycle, and pedestrian access and periodically rendered the road impassable. At these times, the road was closed, and a 17-mile detour went into effect.

This project will improve the crossing of the Cuyama River under all weather conditions for residents and commercial traffic and improve emergency access during rainy periods. The new 1,430-foot-long bridge will feature 30 spans across the river, and include two traffic lanes, shoulders, and a pedestrian walkway with LED lighting. Replacement of the existing LWC with an all-season structure will provide uninterrupted access and improved safety year-round.

Achievement Engineering is providing on-site special inspection and field and laboratory testing of soils, Portland limestone cement (PLC) concrete, reinforced concrete, aggregate and reinforced steel per Caltrans specifications.

The Foothill Low Water Crossing Bridge is the first California Bridge Project to use PLC in the concrete.
