SR-91 Early Action Projects

About the SR-91 Early Action Projects
State Route 91 (SR-91) is a major east-west transportation corridor and is integral to the Southern California freeway network. To improve traffic flow along the freeway, the Los Angeles County Metropolitan Transportation Authority (Metro) and the California Department of Transportation (Caltrans) District 7, in collaboration with the Gateway Cities Council of Governments (GCCOG) are proposing improvements on SR-91.

SR-91 Early Action Projects
Metro completed a Feasibility Study in 2015 which analyzes and identifies several “hot spots” on SR-91. These “hot spots” are chronic traffic congestion areas attributed to population/employment growth, increased trucking activity due to economic growth in the goods movement industry, and deficiencies in design, capacity, and operations of an older freeway system.

The Early Action “hots spots” Projects(EAP) on SR-91 are currently undergoing environmental assessment for final design approvals and will be constructed within the next 2-5 years. The EAP’s have been developed and advanced to address the short-term needs on SR-91. These projects are focused on improving some of the most congested sections of SR-91.

Proposed Early Action Improvements SR-91
Metro and the California Department of Transportation (Caltrans) in collaboration with the Gateway Cities Council of Governments and the San Gabriel Valley Council of Governments, are proposing early action improvements to this corridor, including:

  • Operational enhancements
  • Ramp reconfigurations to enhance safety
  • Arterial intersection enhancements
  • Auxillary lane improvements
  • Safety features
