Interstate 210 Pavement Project

Location and Limits

In Los Angeles County from Wheatland Ave in Lake View Terrace to Interstate 5 in Sylmar

The Project

The I-210 Project will replace pavement on 52 lanes miles of I-210 from State Route Wheatland Ave to Interstate 5 to provide a minimum service life of 40 years. The on and off-ramps, connectors and adjacent shoulders will also be rehabilitated.

Overhead sign structures, traffic loop detectors, center median barrier, and the guardrail system will be upgraded. The freeway lighting system and traffic signals at on and off-ramps will be improved. Existing curbs ramps will be upgraded where necessary to comply with the Americans with Disabilities Act (ADA). The project will also add stormwater treatment devices to eliminate trash from storm water drain systems.


9.7 miles


The rehabilitation is estimated to provide 40 years of service life to the pavement and provide a smoother ride for motorists.


Summer 2020 through Winter 2023/2024

Concerned Communities

San Fernando, Lake View Terrace, Sylmar and Los Angeles County

Total Project Costs

$135.5 Million – Funding provided by SB 1 (Road Repair and Accountability Act of 2017)


Q: Will the speed limit be reduced in the construction zone?

A: California Highway Patrol officers regularly patrol the area to enforce the 55 mile-an-hour speed limit. Motorists are encouraged to “Slow for the Cone Zone” and be “Work Zone Alert.” Traffic fines are also doubled in construction zones.

Q: Will there be full closures of the freeway for this project?

A: Yes, there will be extended weekend closures (EWC) that will include full closures of I-210 on Friday and Sunday evenings, but only in one direction. The project is scheduled to have at least four EWC’s on eastbound I-210 from I-5 to Roxford Ave and five EWC’s on westbound I-210 from Roxford Ave to I-5. Caltrans will issue a notice when EWC’s are scheduled to occur.

Q: Will detour routes be posted when full closures occur?

A: Yes, the contractor will place signage along the detour route if you need to continue your commute. Detour routes and full closure notifications will be publicized on social media.

Q: Will Caltrans close consecutive on and off-ramps at the same time?

A: Consecutive ramps will be closed simultaneously during extended weekend closures. Caltrans will limit consecutive ramp closures to a minimum during regular overnight closures.

Q: Will all the ramps be closed at the same time?

A: The contractor requests closures ahead of time in case certain ramps need to be closed to bring in construction equipment, or for emergencies. Our traffic management center updates closures regularly on the Caltrans QuickMap when crews call in to open or close a ramp.

Q: Will any on/off-ramps be closed long-term?

A: Yes. Various on and off-ramps of I-210 can have a long-term closure of 45 days in the project area. Caltrans will issue a 30-day notice on social media websites when this activity occurs.

Q: Why do the ramps need to be closed for a long period of time?

A: The ramps needs to be closed for an extended period to allow workers a safe space to pave lanes of the highway. Additionally, lanes will be realigned to accommodate the paving work.

Q: Will any connectors be closed?

A: The I-210/I-5 and I-210/SR-118 connectors can be closed overnight or during extended weekend closures.  

Q: Will any city streets be closed?

A: Crews are able to close city streets overnight.

Q: How will lanes be realigned?

A: At various stages of the project, there are plans to have a bypass lane on either westbound or eastbound I-210 once the center median barrier is demolished. The bypass lane helps with traffic flow during peak hours and allows all traffic lanes on I-210 to remain open when there is construction.

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: When will the project start?

A: Summer 2020

Q: When is the project expected to be complete?

A: Spring 2023

Q: Will this project install sound walls?

A: No. This is a paving rehabilitation and bridge widening project. Since the passage of Senate Bill 45, the Los Angeles County Metropolitan Transportation Authority (Metro) is now the agency responsible for noise abatement inquiries and sound wall projects within Los Angeles County.

Q: Is the freeway being widened for additional lanes or a carpool lane?

A: No. The project will only rehabilitate the pavement and upgrade current highway facilities.

Q: Does the project involve landscaping?

A: A minimum amount of landscaping using drought tolerant foliage will be done where feasible.

Q: Were any trees removed for this project?

A: No. Only trees determined to be diseased were removed for the safety of workers and motorists.

Q: What are the structures you are building on the sides of the freeway?

A: Crews are constructing storm water treatment devices to eliminate trash from going into storm water drain systems. The devices will be composed of Biofiltration Swales, Austin Vault Sand Filter, Gross Solid Removal Devices, and Bioswales.

Q: Are you updating the drainage system?

A: Yes, we are installing a new drainage system. The upgrades will meet current Caltrans regulations.

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 invests approximately $5 billion per year to fix roads, freeways and bridges in communities across California, as well as strategically investing in transit. To date, Caltrans has completed more than 100 SB 1 highway projects with nearly another 500 projects currently in the works statewide and many more to come after that. This includes repairing or replacing 115 bridges and paving nearly 1,500 lane miles of the state highway system. In the coming years, SB 1 improvements will be even more visible to the public, with many big projects soon to go out to bid. For example, in our current fiscal year 2019-20, $5.5 billion of new work from multiple funding sources including SB 1 — or $2.5 billion more than last year — will go out for bid. Caltrans is committed to conducting its business in a fully transparent manner and detailing its progress to the public. Complete details on SB1.

Batch Plant FAQs

Q: What is the function of the batch plant?

A: The batch plant combines various ingredients such as water, rock, cement and sand to produce concrete. The concrete will be used to repave the road on I-210.

Q: What are the hours of operation for the batch plant?

A: Hours will vary depending on construction activities.

Q: What are the hours, days and times of construction activities?

A: Seven days a week. Construction will mainly take place from 7 p.m. to 6 a.m. during the weekdays. Contractors can work during the daytime behind k-rail to prevent disruption to traffic flow. On weekends, there will be 55-hour extended closures for paving activities.

Concrete Crusher Operations FAQs

Q:  What is the function of the concrete/rock crusher?

A:  Equipment designed to reduce large pieces of concrete and rock into smaller pieces and gravel.

Q:  What will the operations occur?

A:  Hours and days are Monday through Friday, 6:30 a.m. to 4 p.m.  Work hours will vary depending on construction activities.

Q:  What are the expected impacts?

A:  Residents and local businesses near the freeway may notice noise, vibrations and dust associated with the crushing operation. Caltrans will make every effort to mitigate noise associated with construction activities. Noise levels will not exceed state and federal regulations. Water trucks will be used to minimize dust during working hours. Dump truck drivers will minimize backing up operations to reduce back-up alarm noise. 

Q:  How long will the concrete/rock crusher be in use at this location?

A:  The plant will be in use for paving and concrete center median work. The crusher will cease operation once paving activities conclude and the broken rubble pile is crushed into aggregate. 

Q:  Where did that large pile of concrete come from? 

A:   The concrete was removed from the existing structures, barriers and pavement.  In keeping with our efforts to enhance the environmental sustainability, it will be recycled and used as new concrete in this and other construction projects.
