Overnight closures are scheduled for all northbound and southbound lanes on Interstate 5 (Santa Ana Freeway) between Interstate 605 (San Gabriel River Freeway) and Norwalk Boulevard to remove falsework (temporary frame) from the Florence Ave. Bridge. Closures are subject to change and are scheduled as follows:

I-5 full freeways closures to remove the shims from the bridge falsework (temporary frame) were completed last week. In the coming weeks, workers will continue to disassemble falsework, pave the remaining southbound lanes beneath the bridge, and begin constructing a pedestrian walkway and traffic barrier rail on the bridge.

Workers have also been building the filtration basin for the drainage system at the loop on ramp to southbound I-5. Photo below:

The Florence Ave. on ramp to northbound I-5, and the Florence Ave. off ramp from northbound I-5 will all remain closed until the second half of the Florence Ave. Bridge is complete. This is per request by the cities of Downey and Santa Fe Springs, to minimize traffic congestion until the three additional bridge lanes are provided to handle the increase in vehicles. Construction of the second half of the bridge is underway.
