The contractor poured the first layer of concrete (lean concrete base or LCB) on the connector from northbound I-5 to I-605 and then poured the final blacktop. Photos below:

Workers poured and leveled another layer of lean concrete base for the next section of the Florence Ave. on ramp to northbound I-5. Then they spray a white sealant over the LCB. Photos below from April 30:

The contractor has demolished the old freeway lanes in the median of I-5 south of the Florence Ave. Bridge. They will now lower the roadway surface up to four feet passing under the bridge before repaving. Then construction of the second half of the Florence Ave. Bridge will begin. The contractor will set up a “crusher” conveyor that will crush all of the concrete and asphalt that has been demolished into small aggregate that will be recycled to create base for the new lanes. Photos below:

Orr & Day Rd. south of Florence Ave., 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 projected to begin by late summer.
