On the night of Thursday, October 8 westbound traffic lanes on Florence Avenue were shifted to the outside of the bridge.

The contractor has completed constructing a traffic barrier rail in the median of I-5 from north of Imperial Highway under the bridge  to I-605. Video below from October 7:


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.
