CURRENT AND SCHEDULED WORK (temporary traffic conditions) - Updated NOVEMBER, 2017

  • The current work involved replacing concrete pavement on outside lanes between SR-2 and SR-134. New concrete barriers, metal beam guardrail, approach slabs, sign structures, and tunnel lighting is also currently being performed. 
  • Starting Dec. 4, the eastbound 210 Angeles Crest loop on-ramp (heading toward Foothill Boulevard) will be closed for up to 45 days through 2017.
  • Since Nov. 13, the eastbound I-210 Ocean View on-ramp has been closed long-term. It is expected to reopen the second week of December.
  • Beginning Oct. 30, 2017, the westbound I-210 Berkshire Place on-ramp and Foothill Boulevard off-ramp will be closed for crews to repave the roads across the ramps. Both the Berkshire Place on and Foothill off-ramps are expected to reopen Nov. 29.
  • Starting Oct. 30, the westbound I-210 connector to the Del Mar Boulevard and California Boulevard exit will be closed for tunnel upgrades. The closures are from 11 a.m. to 7 p.m. daily (excluding weekends), and continue through November. During the closures, crews will install permanent tunnel lighting to enhance visibility.
  • On Sept. 25, 2017, the westbound I-210 Berkshire Place off-ramp was closed long-term to repave the roads across the ramps and to replace guardrail. The off-ramp reopened Oct. 28.
  • Beginning August 21, both eastbound and westbound inner shoulders between Lincoln Avenue and Foothill Boulevard will be used as traffic lanes. The eastbound inner shoulder will become a temporary bypass lane for westbound traffic. Two outer lanes on westbound I-210 will close as crews begin to replace the pavement along the freeway, these closures will remain in effect through spring 2018. The bypass lane allows all traffic lanes on westbound I-210 to remain open while work is underway.
  • Various lanes, ramps, and connectors along I-210 from Lowell Avenue to Mountain Street will close intermittently during weeknights between the hours of 7 p.m. and 6 a.m. through summer 2018.

Please Note: Construction activities and closures are weather-permitting and subject to change

 

 


 

 

 



Q: What are the hours, days and times of construction activities?
A: Monday through Friday, each night from 7 p.m. to 6 a.m. Some on/off-ramp and connector closures start and end later (up to 1 p.m. on Saturdays).

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

Q: Will all the ramps be closed at the same time?
A: No. Not all ramps are closed at the same time. The contractor requests closures ahead of time in case certain ramps need to be closed to bring in construction equipment, or for emergencies. At least one lane will be open at all times in both directions. Our traffic management center updates closures regularly on the Caltrans QuickMap when crews call in to open or close a ramp.

Q: Why are certain on/off-ramps closed long-term?
A: The long-term ramp closures are needed to repave the roads across the ramps and repair guard rails.

Q: How many days are certain on/off-ramps closed long-term?
A: 45 days, but the on/off-ramp could reopen in as soon as 30 days.

Q: Will detour and closure signs be posted?
A: Yes. Since the start of construction in April 2015, extended closure signs have been posted at the start and end of the construction zone. 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: How many miles of lanes are being replaced?
A:90 lane miles along an approximately 10-mile section of I-210 from Dunsmore Avenue in the La Crescenta area to North Los Robles Avenue in Pasadena.

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: When did the project start?
A: April 2015

Q: When is the project expected to be complete?
A: Summer 2018

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

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 was used to construct the inside median shoulder along I-210 and it is currently used to repave the road on I-210. 

Q: What are the hours of operation for the batch plant?
A: Monday through Saturday, 7 p.m. to 6 a.m. Hours will vary depending on construction activities. 

Q: What are the hours, days and times of construction activities?
A: 7 p.m. to 6 a.m. Monday night through Saturday morning. Some construction activities will start and end later (up to 1 p.m. on Saturdays)

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.
  • Concrete crushing operations will begin after 7 a.m.
  • Water trucks will be used to minimize dust during working hours.
  • Dump truck driver will minimize backing up operations to reduce back-up alarm noise.

Q: How long will the batch plant be in use at this location?
A: The plant will be in use through at least spring 2018, or until it is no longer needed for project work. 

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 an aggregate base for new pavement installed on I-210.

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 is considering alternatives to address SR-710 congestion and mobility constraints. No decisions have been made on any proposed alternatives.

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: When will the operations occur? 
A: Daily operations are Monday through Saturday, and will continue through at least Spring 2018. Work hours will vary depending on construction activities. Concrete crushing will not begin before 7 a.m.

Q: What are the expected impacts? 
A: Residents and local businesses near the freeway may notice noise, vibrations and dust associated with the batching operation. Caltrans is making every effort to mitigate noise associated with construction activities, including the installation of a noise reduction barrier around the plant location. Noise levels are monitored by Caltrans weekly and sent to the city of Pasadena to ensure compliance with state, federal and city regulations. Water trucks will be used to minimize dust during working hours. Sprinklers have also been installed in the material feeder and conveyor belts of the batch plant and concrete crusher, as well as the top of old concrete stock piles where water trucks can't reach.

Q: How long will the concrete/rock crusher be in use at this location? 
A: The plant will be in use through at least Spring 2018.

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, is considering alternatives to address SR-710 congestion and mobility constraints. No decisions have been made on any proposed alternative.

 

The California Department of Transportation (Caltrans) will make temporary lane changes along the westbound Foothill Freeway (I-210) between Berkshire Place and Ocean View Boulevard as part of a pavement rehabilitation project. Crews will restripe and shift lanes towards the median. Both east- and westbound inner shoulders will be used as traffic lanes. The eastbound inner shoulder will become a temporary bypass lane for westbound traffic. The bypass lane allows all traffic lanes on westbound I-210 to remain open while construction activities are underway. Q: Why did Caltrans create a bypass lane? A: On May 3, two outer lanes on westbound I-210 were closed and traffic was shifted towards the median. Both east- and westbound inner shoulders will be used as traffic lanes to allow traffic lanes on westbound I-210 to remain open while work is underway. A concrete barrier will separate eastbound traffic and the westbound bypass lane for motorists' safety.

Q: How many miles will motorists travel on the bypass lane?
A: Once motorists decide to enter the bypass lane, they will travel approximately 3 miles and will not be able exit the lane until arriving at Ocean View Boulevard.

Q: Where will motorists enter and exit the bypass lane?
A: Motorists will enter the bypass lane near Berkshire Place and will exit at Ocean View Boulevard. Please note, motorists exiting the bypass lane will not be able to access the Ocean View Boulevard off-ramp but will instead need to exit at La Crescenta Avenue off-ramp.

Q: Can motorists exit the bypass lane at any time?
A: No, the bypass lane has been created between k-rail and the freeway median. Once motorists enter the bypass lane, the first opportunity to exit the freeway will be at the La Crescenta Avenue off-ramp.

Q: How long will the bypass lane be in effect?
A: The bypass lane will remain open to motorists until winter 2017.

Q: Can a solo driver enter the bypass lane?
A: Yes, single drivers may drive on the bypass lane. The bypass lane is not an HOV lane.

Q: Are there any vehicles prohibited from entering the bypass lane?
A: No, there are no vehicle prohibitions to use the temporary bypass lane.

Q: Is this bypass lane an HOV lane? Are there plans for an HOV lane along I-210?
A: No, this is a temporary lane made for westbound I-210 while construction takes place in the area. Once the work is completed, all lanes will return to their original configuration. Current construction along I-210 is part of a $148.5 million pavement rehabilitation project, and is not an HOV lane project.
