Nighttime driving through the South Bay could be slower again this week.

Caltrans has scheduled another round of overnight lane, ramp and connector closures along SR-91 between Gardena and Cerritos, beginning Monday night, September 28, and continuing through Saturday morning, October 3.

Both eastbound and westbound SR-91 will see lane reductions during overnight work periods.

Several freeway connectors involving I-110 are also subject to closure.

Those include:

• eastbound SR-91 to southbound I-110
• westbound SR-91 to northbound I-110
• westbound SR-91 to southbound I-110
• northbound I-110 to westbound SR-91
• southbound I-110 to westbound SR-91

Some ramp and connector closures may run until 6 a.m. or later, especially during the Friday-night work window.

Caltrans says the work is part of a $34 million sign rehabilitation project covering nearly 15 miles of SR-91 in Los Angeles County, with completion expected in 2029.

Drivers heading east or west through Gardena, Carson, Compton and Cerritos should check traffic conditions before leaving and allow extra travel time.
