Motorists planning to drive where Interstates 5 and 805 meet with State Route 56 in San Diego Monday night into Tuesday morning, be aware of a slew of lane closures which may affect you. From 8 p.m. Monday to 5 a.m. Tuesday, Caltrans will close all but one lane of the southbound I-5 between the S R-56 and the I-805 split, plus the southbound I-5 bypass and the westbound SR-56 connector to the southbound I-5. Caltrans will close all but one lane of the southbound I-5 between the SR-56 and the I-805 split, plus the southbound I-5 bypass and the westbound SR-56 connector to the southbound I-5 overnight on July 20 to July 21, 2026.

During the entire repair, one lane of southbound I-5 will remain open during the closure and the I-805 will be fully open, Caltrans said. Westbound SR-56 drivers can exit at El Camino Real/Carmel Valley Road (Exit 1B), turn right to the northbound I-5 on-ramp, exit Del Mar Heights Road, and turn left to the southbound I-5 on-ramp, Caltrans said. Crews have placed signs along the routes advising of the closure and suggesting alternate routes. ...read more read less
