The contractor installed a rebar “mat” across the soffit (underside) and outer “stem walls” of the deck of the second half of the new Florence Ave. Bridge over I-5 and constructed rebar frames for stem walls across the center of the deck. Workers have been encasing the stem wall frames in lumber forms in preparation for the first concrete pour. Video below from Dec. 10 and January 14 of 2020:

Crews are now excavating  the closed lanes on the west side of I-5 to lower them up to four feet as they run beneath the new bridge and then re-paving. Photos below from December 3, 2019 through January 7, 2020:

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.
