NV5 - Black Canyon Road Bridge

Black Canyon Road Bridge

Black Canyon Road is an Indian Reservation Road that passes through the Cleveland National Forest. The bridge spans a steep canyon over the Santa Ysabel Creek.

The County of San Diego retained NV5 to perform a review of their 1995 in-house design to replace a functionally obsolete and structurally deficient bridge. Because the project had been shelved for an extended period of time, the design did not meet current standards, specifically the current version of Caltrans’ Seismic Design Criteria.

Subsequently, NV5 was awarded a contract to re-design, create details and specifications, and to obtain approval from Caltrans Local Assistance in order to comply with the requirements of the Highway Bridge Replacement and Rehabilitation Program (HBRR), currently known as the Highway Bridge Program (HBP).

NV5 provided the plans, specifications, and estimate (PS&E) package in record time to avoid loss of funding, and performed a hydraulic and scour analysis to demonstrate that the proposed foundations were adequate. Our report was submitted and approved with no substantial comments. NV5 also provided as-needed construction support services.
