SANTA MONICA ( — Drivers on Pacific Coast Highway and throughout the Westside were urged to use caution Tuesday as the first of three concrete pours for the California Incline Bridge deck gets underway.

Crews began pumping more than 1,000 cubic yards of concrete to the deck portion of the bridge starting at 7 a.m., according to city officials. The pour was expected to last until approximately 3 p.m.

An iconic Southern California symbol, the California Incline is being reconstructed to meet current seismic standards. Once completed, the Incline will feature a wider, safer bridge with improved bicycle and pedestrian access.

Officials closed the bridge between Ocean Avenue and Pacific Coast Highway in April with plans for it to be completely demolished and rebuilt before spring 2016. The Incline was last renovated in 1930.
