CURRENT WORK IN PROGRESS (temporary traffic conditions)

The work involves replacing concrete pavement and shifting traffic toward the median.

  • The eastbound traffic shift took place October 18, 2016.

  • The westbound traffic shift took place January 6, 2017.

  • On January 24, 2017, the eastbound I-210/Pennsylvania Ave on and off ramps were closed to construct the new pavement across the ramps. These ramps are scheduled to re-open in 30 days, weather permitting.

  • As part of staging, excavations have been made along a three mile stretch between Lowell Avenue and Ocean View Boulevard/State Route 2. This road section will get a rock base and then concrete poured on top in a continuous section. Until this is completed, K-rail will remain in place to protect motorists.

  • The concrete paving on eastbound I-210 is anticipated to be complete by approximately June 2017, and the concrete paving on westbound I-210 is anticipated to be complete by approximately September 2017. The temporary lane striping will remain shifted toward the median since the work will progress toward La Cañada-Flintridge and Pasadena, but Caltrans will work with the contractor to modify the transitions at the on-ramps. K-rail may remain as required in order for the contractor to protect workers and motorists to complete remaining items, including guard rail, grinding, final striping, electrical work and irrigation. Of course, these dates are weather permitting and may be adjusted if heavy rains continue.

    TRAFFIC ENHANCEMENTS

    The following efforts have been implemented to enhance and improve the Traffic Handling Plan (THP) as a result of project reviews and to address public concerns (noted in quotes below):

    Advance Warning: “Signage is poor”

    • Eight general PCMS indicating “ROAD WORK AHEAD” are installed throughout the project.

    • In early November 2016, additional portable changeable message signs (PCMS) and temporary construction warning signs including merge warning signs at on ramps were installed in the eastbound direction at Lowell Ave, La Crescenta Ave and Ocean View Blvd for enhanced movement of traffic. Eastbound PCMS messages are:

      “BE ALERT FOR MERGING TRAFFIC NEXT 2MI” (Lowell Ave off ramp)

      “WORK ZONE SPEED LIMIT 55 MPH” (Lowell Ave on ramp)

    • On January 10, 2017, one PCMS was placed westbound just past the La Crescenta Ave off ramp to indicate that the “RIGHT LANE ENDS 1,000 FEET.”

    • Larger-screen PCMS have been requested for greater visibility.

    • On January 31, additional “SPEED STRICTLY ENFORCED” PCMS signs have been requested.

      Speed Monitoring: “Accidents”

    • The project includes construction warning signs (orange panels) indicating the 55 mile per hour construction zone speed limit for day and night. Larger sign panels will be ordered for greater visibility.

    • California Highway Patrol has been enhancing and enforcing safety in the construction zone from 7:30 p.m. to 6 a.m. On November 1 and December 30, 2016, CHP was requested to increase patrols for speed enforcement and safety.

    • On January 31, 2017, CHP confirmed that they will add more patrols between 9 a.m. and 3 p.m.

    • Caltrans is continuously reviewing the job-site and THP to make adjustments or improvements as needed.

      Advanced Warning: “Merge lanes are poor”

    • Additional traffic channelizers and pavement marking (e.g. merging arrows)

      and striping were installed at various locations near on and off ramps throughout the project in December 2016 and January 2017.

    • On January 17, 2017, lane drop arrows were added at the eastbound on-ramps from Lowell Ave, La Crescenta Ave, and Ocean View Blvd.

    • On the westbound mainline, lane drop arrows were added past the La Crescenta off- ramp to complement the PCMS board placed on January 10, 2017.

    • As of January 31, a request for additional adjustments to striping will be made to enhance transition and improve merging at the eastbound La Crescenta Ave, westbound Pennsylvania Ave and eastbound Lowell Ave on-ramps. This is anticipated to be complete in about one week.

    • The contractor will be requested to park equipment in a location that doesn’t obstruct motorists’ view while merging into traffic.

      Traffic Signal Timing Modifications: “Local Street Congestion”

    • On December 5, 2016, Caltrans reached out to Los Angeles County Department of Public Works to investigate traffic conditions along Foothill Boulevard during the commute period and take suitable actions.

    • On the same day they replied and said that they will have staff investigate and adjust the timing as necessary for the intersections maintained by the County.

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.
