SR-91/I-605/I-405 Corridors Program Project Map

Metro’s I-605 Corridor “Hot Spots” Program targets locations with high accident rates and operational issues on and near the I-605 and SR-91 freeways. The program focuses on freeway segments, ramps, interchanges, and intersections where improvements will have the greatest safety and mobility benefits.

Proposed upgrades include ramp and interchange reconfigurations, intersection and pedestrian enhancements, ADA accessibility improvements, and other safety-focused designs. These improvements are tailored to each location through technical analysis and community input.

Metro has allocated $590 million in Measure R funding for the Gateway Cities Subregion, including $136 million for locally led projects. Projects are in various stages of development and aim to benefit residents, commuters, and freight operators.
