FAQs
Q: How will motorists be impacted by the work?

Q: Will detour routes be posted when full closures occur?
A: Yes, the contractor will place signage along the detour route to continue your commute. Multiple message signs will be placed on several highways to alert motorists of the upcoming closures. Detour routes and full closure notifications will be publicized on social media.

Q: When exactly will the work take place?
A: The first 126-hour closure will take place Wednesday, July 20 at 11:00 p.m. through Tuesday, July 26 at 5:00 a.m. on westbound I-210 between Irwindale Ave and I-605.
The second closure will repeat on eastbound I-210 between I-605 and Irwindale Ave on Wednesday, August 17 at 11:00 p.m. through Tuesday, August 23 at 5:00 a.m.
Q: Are delays expected during the 126-hour closures?
A: Yes, major delays are expected on I-210 near the work zone due to the lanes being reduced. Delays are also expected on I-605 and on local city streets. Caltrans advises motorists to use I-10 or SR-60 as alternate routes, use public transportation on the Metro L Line (Gold) or Metrolink, avoid any travel during the closures, and if possible, work from home.
Q: Will Caltrans close any other facilities?
A: The I-210/I-605 connector will be closed during the closure. Some on and off-ramps will also be closed.
Q: Will any bike or walking trails be affected?
The bridge hinge and diaphragm repairs of the San Gabriel River Bridge will affect the East Side San Gabriel River Bike Trail and West Side San Gabriel River Trail. Caltrans has mitigation measures in place to keep both trails open to users. The work on the bridge overhang and railing will be conducted during nighttime hours to ensure that there are no conflicts between construction activities and the use of the trail under the bridge. The San Gabriel River Trail will be kept open during construction with protective fencing. LA County Parks and Rec’s hours of operation for the trail are from sunrise to sunset. A temporary detour plan will also be in place for trail users that would prefer to not use the bike trail underneath scaffolding.
Q: Will any on/off-ramps be closed long-term?
A: No.
Q: Will any city streets be closed?
A: There are no plans to close city streets. However, it is anticipated that a higher traffic volume will be on local city street to avoid the closure. Caltrans advises motorists to avoid the area and local city streets.
Q: How will lanes be realigned?
A: Crews will be fully closing one direction of I-210 and diverting traffic across the median barrier to the opposite direction. This staging will allow I-210 to remain open with three lanes in both directions.
Q: Will detour and closure signs be posted?
A: Yes. Signs alerting drivers that there may be temporarily closures are also at every ramp in the construction zone. Electronic changeable message signs with detour and closure information will be posted at various locations around the construction zone during construction hours.
Q: Is the freeway being widened for additional lanes or a carpool lane?
A: No. The project will only upgrade current highway facilities.
Q: Is this project benefiting from Senate Bill 1 (SB 1) funding?
A: Yes, this project is being funded by SB 1, the Road Repair and Accountability Act of 2017. 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.
