I-605 Corridor Improvement Project Overview
The San Gabriel River Freeway, Interstate 605 (I-605), between Interstate 105 (I-105) and Interstate 10 (I-10), is one of the busiest and most congested highways in the greater Los Angeles area. Projected growth in the region’s population and goods movement are expected to further deteriorate the tra�c capacity and operations of I-605. To ease congestion and plan for future growth, operational and safety improvements are needed.
The Los Angeles County Metropolitan Transportation Authority (Metro), in collaboration with the California Department of Transportation (Caltrans), District 7, the Gateway Cities Council of Governments (GCCOG) and the San Gabriel Valley Council of Governments (SGVCOG), is proposing improvements to approximately 16 miles of highway located along I-605, from approximately I-105 to I-10. The I-605 Corridor Improvement Project (project) also includes improvements along Interstate 105 (I-105), Interstate 5 (I-5), State Route 60 (SR-60), and Interstate 10 (I-10).
The proposed project considers and studies multiple alternatives, which are outlined below.
I-605 Alternatives
Improvements will revitalize the heart of Southern California’s freeway network, allowing people and goods to move freely, which will stimulate and support a robust economy, capable of growing with the region and demands of the future.

Study Area Map with Local Improvements
i-605 improvements (approx. 16 miles)> Add one lane on northbound and southbound I-605, either as a general purpose (GP), high-occupancy vehicle (HOV) or ExpressLane
> Convert existing HOV to ExpressLane (Alt. 2 & 3)
> Add auxiliary lanes as needed between on- and o�-ramps
> Improvements to interchanges
> Safety improvement: increase inside shoulder and lane widths to full standard
i-605/i-10 interchange improvements> Add a direct connector HOV lane or ExpressLane from northbound I-605 to westbound I-10 with reverse movement
sr-60 improvements (approx. 5.5 miles)> Add one GP lane on westbound SR-60 from Hacienda Bl to I-605/SR-60 interchange
> Add one GP lane on eastbound SR-60 from I-605/SR-60 > Interchange to 7th Av
> Add auxiliary lanes in the westbound direction leading > up to the I-605/SR-60 system interchange
> Safety improvement: increase lane widths to > full-standard
i-5 improvements (approx. 3 miles)> Add new HOV lane to northbound and southbound > direction from Florence Av through the I-605 interchange
> Add auxiliary lanes as needed between on- and o�-ramps
> Increase lane and shoulder and widths to full standard > to align with new I-5 construction south of Florence Av > and for improved safety
i-605/i-105 interchange improvements> Add a direct connector HOV lane or ExpressLane from> northbound I-605 to westbound I-105 with reverse movement
> Add a direct connector HOV lane or ExpressLane from > southbound I-605 to westbound I-105 with reverse movement
