IV. BACKGROUND
Project No. 919: Wilmington Avenue and 223rd Street - Pull Box Access Improvements is included in the City’s CIP list.
In 2019, the City completed the freeway interchange project at the 405 Freeway and Wilmington and during the construction, the contractor installed the pull boxes serving the traffic signal at the intersection of Wilmington and 223rd under the existing Flood Control Channel Bridge owned and operated by the LA County. Due to the current locations, the LA County traffic signal maintenance division is not able to maintain the traffic signals if it requires maintenance/service. LA County signal maintenance division requested that the City provide accessibility to the pull boxes so that they can maintain the traffic signal at said intersection. The accessibility improvements include the installation of entry gates, metal ladders, concrete landing pads, safety fences with foundation, anchors for safety lanyards, and clearing and grubbing existing vegetation. Demolition and improvement plans were prepared by P.A. Arca Engineering.
