I-105 ExpressLanes Project

The California Department of Transportation (Caltrans) in cooperation with Los Angeles County Metropolitan Transportation Authority (Metro) are evaluating alternatives to convert the existing high-occupancy vehicle (HOV) lanes to dynamically-priced, high-occupancy toll (HOT) lanes, also called ExpressLanes, in the eastbound and westbound directions of Interstate 105 (I-105) in Los Angeles County from the terminus of the existing HOV lanes west of Interstate 405 (I-405) in the City of Los Angeles to Studebaker Road in the City of Norwalk. The I-105 ExpressLanes Project (Project) limits include the installation of a new overhead tolling system and signage.

The purpose of this Project is to enhance tra­ffic flow; improve trip reliability and travel times; and sustain and manage mobility.

Cities Within the Project Area

This corridor traverses nine cities and unincorporated areas of LA County, including, El Segundo, Hawthorne, Inglewood, Los Angeles, Lynwood, Paramount, South Gate, Downey and Norwalk.

Funding

Measure M, the local sales tax passed by LA County voters in 2016, provides $175 million for this Project.

Draft Environmental Document Is Now Available for Review

The Draft Environmental Impact Report/Environmental Assessment (EIR/EA) , Project Report and Concept of Operations for the I-105 ExpressLanes Project are now available for public review and comment through Monday, July 6, 2020. The Draft Eir/EA and Project Report technical studies, the Traffic and Revenue Study, and printed copies of aforementioned reports are available upon request.

Based on Governor Newsom's executive order as well as recommendations from the California Department of Public Health to stay at home, except as needed, in-person public hearings will not be held to maintain social distancing requirements. However, Metro and Caltrans will host a live presentation and Q&A to share project updates and details on the Draft EIR/EA and supporting documents. Note: Questions submitted for the Q&A will not be part of the official comment record. Comments on the Draft EIR/EA may be submitted via the website comment form and virtual open house or by mail, email or helpline which are publicized on this website.

In 2015, Caltrans completed a Project Study Report/ Project Development Support (PSR/PDS) for the I-105 corridor to assess potential improvements. The PSR/PDS identified four alternatives including a no build, conversion of the existing High Occupancy Vehicle (HOV) lane into ExpressLanes, and the addition of a second ExpressLane in each direction.

In January 2017, the ExpressLanes Strategic Plan was presented to the Metro Board. The Strategic Plan identified three tiers of ExpressLanes projects, with Tier 1 projects showing the highest potential benefits. Tier 1 projects include the I-105, sections of the I-405 and I-605, and extensions of the existing I-10 and I-110 ExpressLanes. The PSR/PDS and ExpressLanes Strategic Plan can be found in the Reports tab.

Next, Metro and Caltrans began the preparation of the Environmental Impact Report/Environmental Assessment to evaluate the environmental effects of this project pursuant to the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA). As part of this effort, Metro hosted public scoping meetings along the corridor in March 2018 and updated community meetings in 2019 to share the latest on the proposed alternatives and project. All past meeting materials can be accessed under Past Meetings section on this webpage.

Current Conditions

The I-105 corridor experiences heavy demand during peak commute hours that exceeds the freeway’s capacity. Today, between 200,000-250,000 vehicles per day use I-105. Peak period speeds average 25 miles per hour or less in the General Purpose (GP) lanes. In addition, sections of the eastbound and westbound I-105 High-Occupancy Vehicle (HOV) lanes are classified as degraded as defined by federal standards. This means speeds on the HOV lanes are less than 45 miles per hour more than 10 percent of the time.

About Metro ExpressLanes

The Metro ExpressLanes Program was initiated as a one-year demonstration to assess the use of congestion pricing to ease traffic on LA County freeways. They were designed to improve traffic flow and provide motorists, including solo drivers, a more reliable travel option in LA County. ExpressLanes allow carpools, vanpools and buses to travel for free, while also providing single occupant vehicles the option to pay a toll to use the lane.

Tolls for vehicles that don’t qualify to travel for free are calculated based on traffic conditions and vary according to the level of congestion – tolls are higher when traffic congestion is heavier and lower when traffic is lighter. Currently, Metro operates ExpressLanes on I-110 and I-10 freeways in LA County. To learn more about Metro ExpressLanes, visit the website or click on the links below.


Metro and Caltrans evaluated the following proposed Alternatives as part of the Draft Environmental Impact Report/Environmental Assessment (EIR/EA):

  • Alternative 1: Existing Conditions (No Build) Maintains its current condition with no changes. No additional travel lanes or ramp improvements would be implemented.
  • Alternative 2: Convert HOV to One (1) ExpressLane Convert existing HOV lane to one ExpressLane in each direction with standard lane widths.
  • Alternative 3: Convert HOV to Two (2) ExpressLanes (Non-Standard Lane Widths) Convert existing HOV lanes to two ExpressLanes in each direction, with non-standard lane and shoulder widths.
  • Alternative 4: Convert HOV to Two (2) ExpressLanes (Standard Lane Widths) initially considered, however it was eliminated from further consideration as it would have resulted in unavoidable, significant environmental impacts.

Staff Recommended LPA

Based on the environmental and technical studies conducted, Alternative 3 is the Locally Preferred Alternative (LPA) with support from some public agencies and/or the public.

Final identification of a Preferred Alternative (PA) will occur after the public review and comment period of the draft environmental document.

Alternatives


On May 22, 2020, Caltrans and Metro released a Draft Environmental Impact Report (EIR) in accordance with the California Environmental Quality Act (CEQA), and a Draft Environmental Assessment (EA) in accordance with the National Environmental Policy Act (NEPA) for this project. The Draft EIR/EA describes the proposed project, any environmental consequences, and avoidance, minimization, and/or mitigation measures. Supporting technical studies for the Draft EIR/EA have also been prepared on traffic, visual, archaeological, water, noise, air quality, biology, geology, hazardous waste, energy, paleontology, and community impacts.

In addition, a Draft Project Report and Concept of Operations (ConOps) have been released. The Draft Project Report provides details on the alternatives including design features, traffic performance, and cost. The ConOps defines operational policies, toll collection systems and facility design. The T&R estimates toll rates and potential toll revenue for this corridor.

The Draft EIR/EA, Project Report, and ConOps for the I-105 ExpressLanes Project are now available for public review and comment through Monday, July 6, 2020. The supporting Draft EIR/EA and Project Report technical studies, the T&R Study, and printed copies of the reports are available upon request. If you’re interested, please submit your request via the project email or helpline listed on the EIR/EA tab of this website.
