Drivers who travel on I-5 between San Clemente and San Juan Capistrano on weeknights can expect to encounter alternating lane and ramp closures over the next few weeks.

“Crews will be installing median and overhead signs and performing electrical work,” the Orange County Transportation Authority said in a traffic advisory. Hours will be 10 p.m. to 5 a.m. Mondays through Fridays.

Also, workers will be installing final touches the next few weeks on a widened Avenida Pico interchange, including planting of landscaping and sign installation, OCTA said.
