The California Department of Transportation (Caltrans) will completely close the northbound Interstate 880 onramp at 23rd Avenue for two weeks starting tomorrow, Friday, Sept. 28, until Monday, Oct. 15. According to Caltrans, the closure is necessary to complete the connector ramp for the new 23rd Avenue overcrossing onto northbound I-880.

Caltrans will post warning messages and detour signs. Project information can be found at www.dot.ca.gov/d4/projects_list.htm.
