We are relocating the fire hydrant and Air Valve Cans (AVC, which release air pressure from the water lines) on the three cul-de-sacs south of Florence Ave. and west of I-5 in Downey: Quinn St., Mueller St., and Buell St. The contractor will move the fire hydrants and  AVC to 20″ behind the curb. Work begins Tuesday, May 26 at 7 a.m. and should complete by mid-June. The cul-de-sacs will remain open, with some restrictions near the work area for truck movement.  Map 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.
