The road remained operational throughout the $2-million project, which was delivered on time and under budget.

Since the mid-1990s, the two-lane road connecting U.S. Highway 1 with Santa Barbara County's Jalama Beach park had experienced excessive cracking and settlement, primarily because of a relocation in the 1960s to a site across from an old landslide. A sinkhole had also developed from a corroded metal pipe that was trapping stormwater runoff behind the roadway. The road remained operational throughout the $2-million project, which was delivered on time and under budget. Specialty work included injection grouting of cement slurry, excavation into the fill of two keyways and boring and jacking a reinforced concrete pipe through the fill. Sub-drains for groundwater were installed, and erosion control was achieved with hydro-seeding.
