Pavement and Slab Replacement Project on the Foothill Freeway (I-210)

Los Angeles - The California Department of Transportation (Caltrans) will make the following improvements along I-210 starting at the Dunsmore Avenue undercrossing in La Crescenta-Montrose to the North Los Robles Avenue overcrossing in Pasadena. Including the cities of La Canada Flintridge and Glendale:

 
  • Replace concrete median barriers and guardrails.
  • Upgrades to the lighting and electrical systems, resurfacing the pavement with High Friction Surface Treatment in the I-210/SR-134 tunnels.
  • Resurfacing pavement and replacing distressed slabs for 16 structures. 
  • Install and upgrade curbs to meet the Americans with Disabilities Act (ADA) of 1990 at about 36 locations.
  • Installing and replacing loop detectors.
  • Re-stripe traffic and pavement makers using thermoplastic paint.
This 9.7 mile project will improve overall traffic operations, provide a smoother and quieter drive for motorists and extend the pavement for
40 years of life, thereby minimizing maintenance-related closures. These improvements will enhance safety and meet current Caltrans standards.
 
The project started April 2015 and will continue through mid-2018. The work will include both day and night time operations. Closures will include multiple lane and ramps daily. Accessibility for motorists will be maintained at all times.  
 

The contractor for this $148.5 million project is Flatiron West, Inc. of Chino Hills, California. Local businesses, motorists and residents may experience traffic delays, noise and vibrations from construction activities. Caltrans appreciates your patience while we work to improve I-210. For additional information contact Jackie Beaver at (213) 897-7602 or Jacqueline.beaver@dot,ca,gov

Project FAQs

Q: What are the hours, days and times of construction activities?
A: Sunday through Friday, each night from 7 p.m. to 6 a.m.

Q: Will Caltrans close on-and off-ramps at the same time?
A: No consecutive ramps will be closed simultaneously

Q: Will this project install sound walls?
A: No. This is a paving and rehabilitation 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. For further assistance, please contact Benkin Jong, Sound Wall Program Manager at (213) 922-3053 or email at jongB@metro.net

Q: How many lanes will this project replace?
A: Numbers three and four lanes and shoulders will be replaced with Jointed Plain Concrete Pavement (JPCP) and Precast Jointed Plane Concrete Pavement (PJCP) at the ramp crossings and on-ramp connectors. The distressed slabs in the numbers one and two lanes will be replaced with Individual Precast Slabs (IPS.) All lanes will be smoothed to improve ride quality.

Q: Does the project involve landscaping?
A: A minimum amount of landscaping using drought tolerant foliage will be done when feasible due to the current drought restrictions within California.

Q: Are you updating the drainage system?
A: Yes, we are installing a new drainage system. The upgrades will meet current Caltrans regulations.

Batch Plant FAQs

Q: What is that large metal structure located at the SR-710 terminus in Pasadena?
A: It’s a concrete plant, also known as a batch plant or batching plant.

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 construct the inside median shoulder along I-210.

Q: What are the hours of operation for the batch plant?
A: Nightly operations will continue Friday, August 28. Hours will vary depending on construction activities.

Q: What are the hours, days and times of construction activities?
A: Sunday through Friday, each night from 7 p.m. to 6 a.m.

Q: What are the expected impacts?
A: Residents and local businesses nearest the freeway may notice noise, vibrations and dust associated with the batching operation. Caltrans will make every effort to mitigate noise associated with construction activities by installing a noise reduction barrier around the plant location. Noise levels will not exceed state, federal and city regulations. Water trucks will be used to minimize dust during working hours.

Q: How long will the batch plant be in use at this location?
A: The plant will be in use through mid- September and will resume operations in late fall 2015.

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 for new concrete for this and other construction projects.

Q: Is this work part of the proposed SR-710 extension?
A: No, the work at the SR-710 terminus is part of the I-210 paving and rehabilitation project between the Dunsmore Avenue undercrossing in La Crescenta-Montrose and the North Los Robles overcrossing in Pasadena. Caltrans, in cooperation with Metro, is considering five alternatives to address SR-710 congestion and mobility constraints. No decisions have been made on any proposed alternative.
