The southbound Santa Ana Freeway (Interstate 5) off-ramp at Pioneer Boulevard/Imperial Highway will be closed beginning Thursday, August 15 at 8 a.m. due to a ramp re-vamp. The ramp will remain fully closed for eight months (through April 2014).

Motorists will have access to off-ramps at:

-Lakewood/Rosecrans

-Florence Ave.

-San Antonio Dr./Norwalk Blvd.

To accommodate increased traffic demand on the southbound I-5 San Antonio/Norwalk off-ramp, it will be restriped and a new signal at Union St./San Antonio Dr. will be modified.

Upon completion, the Ramp Re-vamp will extend the new Pioneer/Imperial Highway off-ramp nearly 1,200 feet from the widened freeway, and it will flyover Pioneer Blvd. to put traffic onto Imperial Hwy.  Motorists will exit the new off-ramp using one lane, but the ramp will widen to three lanes at Imperial Highway.
