    Citywide Bicycle Facilities Detection Improvement Project | City of Lodi

    This Active Transportation Program Grant-funded project upgraded 13 of the City’s major intersections with improvements including the installation of video and loop detection systems and enhanced, high-visibility bike lane striping and bike boxes. Interwest prepared the plans, specifications, and construction estimates for the design of these improvements intended to enhance operational safety and encourage cycling, citywide.
  • El Paseo Drive Enhancement and Traffic Calming Improvements | City of Palm Desert

    El Paseo Drive Enhancement and Traffic Calming Improvements | City of Palm Desert

    The City of Palm Desert invested approximately $1M in pedestrian improvements along El Paseo Drive, the City’s premier shopping and entertainment corridor. Project improvements included high visibility, brightly colored intersection crosswalks, upgraded ADA access ramps, and painted bulb-outs at two major intersections along El Paseo. Other improvements included brightly painted, highly visible speed tables at three pedestrian-activated mid-block crossings controlled by rectangular rapid flashing beacons. Interwest prepared the plans, specifications and construction estimate for the design of these improvements in support of the City's goal of enhancing pedestrian safety and multi-modal transportation along El Paseo. Our team also provided project management support through the construction phase to project completion.

  • La Novia/Valle Roundabout | City of San Juan Capistrano

    La Novia/Valle Roundabout | City of San Juan Capistrano

    This $2.6M project completed in March 2017 was the first roundabout constructed in the City of San Juan Capistrano and the first at a freeway interchange in Orange County. The roundabout replaced the existing offset intersection to reduce congestion and enhance traffic safety. It also provided traffic mitigation for several large subdivision projects in the near vicinity. The roundabout involved multi-agencies including the Federal Highway Administration and Caltrans. George Alvarez managed the project and he, in partnership with FHWA and Caltrans, presented the roundabout alternative to the City Council and approved it to move forward with design. The project recently received an award for the APWA Southern California Chapter for Best Design.
