Caltrans Announces Five-Day Closure of Eastbound I-210 at San Gabriel River Bridge
IRWINDALE – The California Department of Transportation (Caltrans) announces a five-day closure of westbound Interstate 210 (I-210) at the San Gabriel River Bridge in Irwindale for a bridge upgrade project partially funded by Senate Bill 1 (SB 1). Crews will divert traffic from eastbound I-210 to westbound I-210, which will be converted to three-lanes in both directions between Interstate 605 (I-605) and Irwindale Ave. during the closure.  The following closures will be taking place Wednesday, August 17, at 10:00 p.m. through Tuesday, August 23, at 5 a.m.:

  • Eastbound I-210 from I-605 to Irwindale Ave. 
  • Westbound I-210 Irwindale Ave. on-ramps  
  • Westbound I-210 to southbound I-605 connector 
  • I-605 to eastbound I-210 connector 
  • Eastbound I-210 Mt. Olive Dr. on-ramps
Trucks over seven tons are prohibited on Huntington Dr. in the city of Duarte and will be subject to traffic enforcement. Message signs on the highway will be alerting trucks to use designated alternate routes.  
Caltrans advises motorists to expect major delays, use I-10 or SR-60 as alternate routes, use public transportation on the Metro L Line (Gold) or Metrolink during the closures and if possible, work from home.

The closure schedule is subject to change due to weather, availability of equipment and materials, and construction-related issues. Motorists are encouraged to plan ahead and check the Caltrans QuickMap for up-to-the-minute traffic conditions. More information and updates on this project can be found on the District 7 website or on Twitter

The work is part of a project to upgrade San Gabriel River Bridge on I-210 in Irwindale. The $30 million project – which includes $1.7 million from SB 1, the Road Repair and Accountability Act of 2017 – will upgrade existing bridge hinges and railings and strengthen bridge decks to improve safety. 

SB 1 provides $5 billion in transportation funding annually split between the state and local agencies. Road projects progress through construction phases more quickly based on the availability of SB 1 funds, including projects that are partially funded by SB 1.
