Caltrans Extends Major Closures of Interstate 8 in San Diego

A major detour project is underway again on Monday night on Interstate 8 in Mission Valley, continuing through Thursday.

Most drivers who hoped to travel on a two-mile portion of Interstate 8 in western Mission Valley on a series of nights last week were shocked to discover just a single lane of the eight-lane freeway opened for evening traffic.

Construction crews will be closing "freeway connectors, on-ramps, off-ramps, three inside lanes of westbound Interstate 8 (I-8) and all lanes of eastbound I-8 … from Interstate 5 (I-5) to State Route 163 (SR-163)" from 9 p.m. to 5 a.m. for a portion of this week as well, officials said.

🚧Caltrans crews have more closures planned for tonight and Monday night for a paving project along Interstate 8 in #MissionValley. The latest closure and detour information can be found here: https://t.co/LEQleWKttp @CaltransHQ @CityofSanDiego #BeWorkZoneAlert pic.twitter.com/YixUufgimU

The closures are just the beginning: Intermittent lane closures are expected for the next two months as well, according to Caltrans.

The scheduled work includes the installation of rumble strips and the upgrading of striping, as well as a roadway overlay treatment that is intended to extend the life of the pavement.
