Scope Of Work
T.Y. Lin International (TYLI) provided bridge design services for the California Incline Bridge Replacement project in Santa Monica, California. Replacing a series of sidehill viaducts built in 1930, the new bridge cuts through the steep shoreline slopes of Pacific Palisades Park and connects the intersection of Ocean and California Avenues atop the bluffs to Pacific Coast Highway at the base. The firm also oversaw traffic and electrical engineering, geotechnical engineering, hazardous material testing, and surveying.
TYLI designed the bridge to accommodate the corrosive marine environment and high seismic demands, including up to 20 feet of potential bluff erosion that could occur over its 75-year life span. The California Incline Bridge consists of a 750-foot-long cast-in-place, post-tensioned slab structure, with a total width of 52 feet to carry both vehicular traffic and a new bicycle/pedestrian path.
PROJECT HIGHLIGHTS:
TYLI conducted a detailed type selection process to determine the best replacement alternative.
Bridge spans and deep concrete piles were specifically located to minimize damage and erosion to the coastal bluffs.
A 12-inch water main was replaced in the roadway and under the bridge, with bridge piles adjusted for the waterline.
TYLI designed a temporary “high line” to maintain water service for residents during construction.
Aesthetic elements include the decorative bridge railing, overhang, and corbels.
LED lighting was placed along the barrier-separated bicycle/pedestrian path.
The historic "Santa Monica" sign was refurbished and mounted on a TYLI-designed monument.
