Metro ExpressLanes is a pilot, one-year demonstration program overseen by Metro, Caltrans and several other mobility partners that have joined forces to develop a package of solutions to improve traffic flow and provide enhanced travel options on the I-10 and I-110 Fwys. in Los Angeles County.

The program includes the introduction of congestion pricing by converting High Occupancy Vehicle (HOV) lanes to High Occupancy Toll (HOT) lanes; the improvement of transit service and other alternatives to driving; the updating of transit facilities; and the improvement of parking in downtown Los Angeles.

It is about improving mobility and offering a safe and reliable trip for users. Everyone benefits with reduced congestion and greenhouse gas emissions, increased travel time savings, and better trip reliability. Metro ExpressLanes is primarily funded with a $210 million congestion reduction demonstration grant from the U.S. Department of Transportation. Tolling began November 10, 2012 on the I-110 and on February 23, 2013 on the I-10. The one-year congestion reduction demonstration grant funding ends February 23, 2014 for the I-110 and I-10.

Metro ExpressLanes features include:

  • Conversion of the I-10 El Monte Busway HOV lanes (I-605 to Alameda St) to HOT lanes
  • Conversion of the I-110 Harbor Transitway HOV lanes (Harbor Gateway Transit Center (formerly Artesia Transit Center) to Adams Bl.) to HOT lanes
  • 59 new alternative fuel expansion buses and operating subsidy for the demo period 
  • El Monte Station Expansion
  • New Transit Station at Patsaouras Plaza

I-110 High-Occupancy Toll Lanes Flyover Project

Caltrans and Metro are studying the construction of a new off-ramp at the Northbound 110 Adams Boulevard ExpressLanes exit to connect traffic directly to Figueroa Street.  

A public hearing will be held on Tuesday, February 23, 2016, from 6- 8pm at:

Orthopaedic Institute for Children
Andrew Norman Hall
403 West Adams Boulevard, Los Angeles, CA 90007 

Project Description
Caltrans, in cooperation with Metro, proposes to construct an elevated off-ramp structure on the NB I-110 between 30th St. and Figueroa St. overcrossing in the City of Los Angeles. The proposed structure would bypass the bottleneck intersections at Flower St. and Adams Blvd. and NB I-110 HOT off-ramp to Adams Blvd., connecting the HOT lane traffic to Figueroa St. The structure would be approximately 1,400 feet in length with two standard lanes (12 feet in width) and a four-foot left shoulder, as well as an eight-foot right shoulder will be provided. At its highest point at Adams/Flower, the flyover height would be approximately 54.5 feet. All new structures will be within State right of way; however, a three-foot strip of right of way acquisition will be required for maintenance, ingress/egress, access control, and setback purposes, as well as emergency services access. This right of way is located at the rear of the strip mall at Figueroa/Adams and is currently used for parking. Furthermore, Figueroa Way would be closed to traffic, but approximately a five- foot wide strip will be used by bicyclists and approximately an eight-foot wide strip will be used by pedestrians on Figueroa Way. The project is being planned in coordination with the City of Los Angeles’ My Figueroa Project (MyFig Project) on Figueroa St.

Purpose and Need
The purpose of the project is to alleviate congestion and reduce the queuing and delay on the managed HOT lanes, Adams Blvd. off-ramp, and associated nearby intersections. The current termination of the northbound I-110 HOT lanes at Adams Blvd. presents a particularly challenging bottleneck, as approximately half of the HOT lane traffic exits here to access downtown Los Angeles via Figueroa St., which affects the nearby intersections of Flower St. & Adams Blvd. and northbound I-110 HOT off-ramp to Adams Blvd. The existing northbound HOT lane at Adams Blvd. is a concentrated accident location, which is a safety concern.
