Florence Avenue Interchange

Improvements:

The Florence Avenue Bridge will be widened from the existing four lanes to six lanes. The new bridge will also be approximately three feet higher and 321 feet longer. Finally, pedestrian access will be improved and on and off-ramps are being reconstructed and realigned to accommodate the I-5 freeway widening.

This project is 78% complete.

Construction of the first half of the Florence Ave. Bridge is complete. Construction of the second half of the Florence Avenue Bridge has been moved to the final phase of construction with a projected completion date of early 2020. We expect to begin construction this summer.

During the last week of April, the first layer of concrete (lean concrete base, or LCB) was been poured on a section of the northbound I-5 connector to I-605. The next week that layer was covered with blacktop. Photos below:

Workers have been pouring the lean concrete base for the next section of the Florence Ave. on ramp to northbound I-5:

The contractor completed placing forms over the rebar frame of the traffic barrier rail along the retaining wall that separates the Florence Ave. on ramp to northbound I-5 (above) from the northbound I-5 connector to I-605 (below). Concrete was poured and the forms removed. Photos below from April 30 and May 7:

Project Overview

The Santa Ana Freeway (Interstate 5) Florence Avenue Interchange Project will widen I-5 to add one High Occupancy Vehicle (HOV) or carpool lane, and one general purpose lane in each direction. The project extends through the cities of Downey and Santa Fe Springs to just north of the San Gabriel River Freeway (Interstate 605) bridge.

The freeway improvements include widening structures at Florence Avenue and Orr and Day Road, shoulder widening, median barriers, new on-ramp and off-ramp designs, and reconfiguring the Florence Avenue interchange at the I-5. The Florence Avenue overcrossing will be widened from four lanes to six lanes.
