High Street Onramp to Northbound I-880 Closed this Weekend


ALAMEDA COUNTY – A 36-hour closure of the High Street onramp on northbound (NB) Interstate 880 (I-880) will take effect Friday, March 1, 2013 from 11 p.m., to Sunday, March 3, until 11 a.m.

Construction crews are expected to complete the final asphalt concrete resurfacing of the onramp during the closure. Once completed, the High Street onramp will be a two-lane ramp, instead of the existing one-lane ramp.

Detour routes are as follows (see attached detour map):

  • I-880-NB motorists are advised to use the accessible section of the 42nd Avenue onramp, which will remain open during construction operations during the weekend closure. Please travel along High Street to San Leandro Street; proceed to 40th Avenue to East 12th Street to access 42nd Avenue onramp to NB I-880.
  • Motorists leaving the City of Alameda are advised to use the Fruitvale Bridge before entering the Oakland to bypass the closure. Alameda motorists should also use the Fruitvale Bridge to East 9th Street to reach NB I-880.

The 36-hour closure is necessary to allow construction crews to safely stage equipment and complete resurfacing construction, while allowing personnel to complete their work safely and with minimal impact to freeway travelers. Nighttime mainline closures on NB and SB I-880 are expected to continue through March 2013


Motorists are strongly urged to drive cautiously through this construction zone and to always leave a safe traveling distance between your vehicle and the vehicle ahead of you.  Caltrans appreciates your patience as we work to improve the highways.  Please remember to “Slow for the Cone Zone.”
