Introduction

Introduction

Yolo 80 Managed Lanes Project

Introduction

Yolo Transportation District (YoloTD) and the California Department of Transportation (Caltrans) have joined forces for a freeway expansion initiative aimed at enhancing traffic flow within the I-80 corridor on the west side of the Sacramento-Yolo metropolitan area. This comprehensive project encompasses multiple components, including the introduction of approximately 17 miles of tolled managed lanes, new lane construction, intelligent transportation system (ITS) enhancements, and improvements to cycling and pedestrian facilities.

A new Joint Powers Authority (JPA) was formed in January 2024 to develop and operate toll facilities in the Sacramento region: the Capital Area Regional Tolling Authority (CARTA). The CARTA board is currently comprised of elected representatives from YoloTD, SACOG, and Caltrans District 3. CARTA also includes non-voting directors from Sacramento Transportation Authority, Placer County Transportation Planning Agency, and El Dorado County Transportation Commission. Voting representation will grow as the Sacramento region’s tolled managed lane network expands into other counties as envisions in the regional Metropolitan Transportation Plan / Sustainable Communities Strategy (MTP/SCS).

Improving Mobility for All

What this Project Will Do

  1. Reduce Congestion – This project will construct a new tolled managed lane along 17 miles of I-80 by restriping, providing the needed capacity without widening the existing footprint of the causeway. Ramp meters, auxiliary lanes and technology improvements will improve the flow of vehicles onto the freeway, reducing bottlenecks.
  2. Prioritize Transit – Unlike conventional freeway widenings, this project is designed to minimize harmful climate emissions. The new lane will be adaptively managed to prioritize transit and carpools. Technology upgrades will detect transit vehicles entering the freeway and give them priority.
  3. Safe, Low-Stress Bicycle Facilities – Yolo County is home to world-class bicycle facilities, including an existing protected bike lane on the Yolo 80 Causeway. This project would upgrade the current bike path and make safety improvements on both the Davis and West Sacramento approaches.
  4. Support Local Communities – The project will reduce dangerous cut-through traffic on local streets and rural roads by travelers seeking to avoid traffic on I-80. A portion of new toll revenue will be reinvested in local communities, with priority given to environmental justice communities.

The Project will construct approximately 17 center-line miles of Tolled Managed Lanes in both directions on Interstate 80 (I-80) and United States 50 (US-50) in Yolo County and portions of Sacramento County to alleviate bottlenecks and address an increasing capacity constraint.

Project components includes installation of Intelligent Transportation Systems (ITS) elements, such as fiber optics, detection, changeable message signs, to enhance mobility conditions and incident management strategies between jurisdictions; and improved bicycle and pedestrian access and safety to the eastern and western termini of the Yolo Causeway Class I facility that includes reduced curve radius, and analyze additional crosswalk, sidewalk, lighting, and safety elements.

The proposed improvements represent a scope guided by a variety of stakeholders from local and regional entities along the corridor. The Project begins at the Solano/Yolo County line on I-80 and ends at the I-80/West El Camino Avenue interchange, and on US-50 from the I-80/US-50 Interchange to the I-5/US-50 interchange, in Sacramento County. The project area includes the entire I-80 and US-50 corridors in Yolo County. This Project will result in direct and significant benefits to the economic vitality of the region by enhancing the operational performance and safety for regional and interregional travelers and national freight movement.

The I-80/US-50 corridors are subject to high travel demand, especially during peak commute periods and recreational weekend travel. The demand has created severe traffic congestion and impaired mobility along the route. At various locations, specifically I-80 through the city of Davis, and along the Yolo Bypass Causeway between the cities of Davis and West Sacramento, travel demand has exceeded highway design capacity, resulting in bottlenecks during the AM and PM peak periods. Multiple factors contribute to these bottlenecks, including high traffic volumes, short weaving and merging areas, lane drops, limited sight distances, lack of ITS elements, and incomplete bus/carpool, ramp metering, and auxiliary lane networks. Heavy congestion and stop-and-go traffic have contributed to increased vehicle emissions, increased travel costs, and reduced travel time reliability.

Project Goals

Project Goals

Improving Mobility for All

Project Goals

  • Support achievement of state and regional climate goals by limiting VMT increases and maximizing VMT reduction strategies.
  • Increase transit ridership and mode share.
  • Increase safety and ease of bicycle travel on the existing causeway bicycle path, including connecting routes in West Sacramento and Davis.
  • Advance transportation equity by minimizing project burdens and maximizing project benefits for low-income communities.
  • Improve peak hour travel time on I-80 while reducing the use of local streets and roads for regional trips
  • Increased coordination with Solano County, Caltrans District 4, and MTC on interregional trips
  • Improve traffic flow by utilizing Intelligent Transportation Systems (ITS) technologies such as ramp metering
  • Establish a highway management system that can be replicated and integrated regionwide.
