Project Stakeholders


The project design and construction is financed by the Federal Active Transportation Program funds granted by the California State Department of Transportation (Caltrans) and County local funds. The wayfinding and monument signage is financed by Local Transportation funds granted by the Los Angeles County Metropolitan Transportation Authority (Metro) and County local funds.

Traffic/Pedestrian Impacts During Construction

Construction activities will require a detour of pedestrians around affected areas.

Substantial completion of the roadway improvements in the vicinity of the Martin Luther King Jr. Community Hospital was accomplished in February 2018. Installation of the wayfinding signs was completed in March. We are currently coordinating with the Los Angeles County Metropolitan Transportation Authority for completion of the remaining roadway improvements listed below.

  1. Traffic signal installation at the intersection of 118th St./Wilmington Ave.
  2. Traffic signal installation and curb ramp reconstruction at the intersection of the 105 Fwy on/off ramps and Wilmington Ave.
  3. Roadway resurfacing of Wilmington Ave.
  4. Installation of loops, striping, and traffic signs.
