|Construction Alert: Nighttime Work Continues on Northbound I-805 Lane, ramp, and connector closures in January SANDAG and Caltrans will be continuing nightly closures along northbound Interstate 805 (I-805) in National City and Chula Vista, January 2-16, between the hours of 9 p.m. and 5 a.m.|
| January 2 – January 16|
Planned closures during this period include up to three outside lanes on northbound I-805 between Bonita and Sweetwater roads, the northbound I-805 to eastbound and westbound SR 54 connectors, the northbound I-805 to Sweetwater Road off-ramp, and the Bonita Road on-ramp to northbound I-805. Additionally, crews will be conducting work under the Sweetwater River Bridge that will result in bike lane delays for cyclists travelling along the Sweetwater River bike path. Flaggers will be in place to ensure access is maintained.
These closures are required for the safety of the public and crews conducting work in the area and will be in effect for the duration of construction. Motorists will be provided with advanced notice of approaching work zones via portable message signs. Detour signage will be in place to direct motorists around these nightly closures. Motorists travelling along I-805 can expect construction noise and heavy equipment within the project area. Your patience during construction is appreciated.
The Sweetwater River bridge and safety improvements project is anticipated to be complete by 2022. speed limit of 55 mph in construction work zones on I-805. This speed limit reduction helps improve the safety of the traveling public, construction workers, and public safety professionals.
