Exciting New Tolling Begins on I-80 Express Lanes

The Metropolitan Transportation Commission (MTC) has announced that tolling for the new Express Lanes on Interstate 80, which stretch through both Fairfield and Vacaville in Solano County, is set to commence on Tuesday, December 16, 2025. This initiative promises to bolster mobility and reduce congestion for countless travelers.

Overview of the Express Lanes

This 18-mile segment of I-80, spanning from Red Top Road in Fairfield to Interstate 505 in Vacaville, previously operated with standard carpool lanes in both directions. The implementation of Express Lanes marks a pivotal shift towards improving traffic flow and reducing travel times for all commuters, especially those seeking access to the greater Bay Area.

With the Express Lanes in operation, users will be required to have a FasTrak® toll tag to access these lanes. The tolled service will be available seven days a week, from 5 a.m. to 8 p.m., catering to the needs of daily commuters.

Toll Structure and Benefits

A detailed structure for tolling has been established, which includes the following key points:

• - Free Travel for Carpools: Vehicles with three or more passengers can travel toll-free using a FasTrak Flex toll tag set to the "3+" position. This is aimed at encouraging carpooling, thereby reducing the number of vehicles on the road.
• - Discounted Rates for Two-Person Carpools: For those traveling with two people, a FasTrak Flex tag set to the "2" position allows them to benefit from half-price tolls.
• - Solo Drivers: Drivers traveling alone will need to pay the full toll to utilize the Express Lanes. They can opt for either a standard FasTrak toll tag or a FasTrak Flex tag, set to the first position.

The tolls are dynamic—they increase as traffic rises and decrease during off-peak hours. Digital signage along the roadway will keep drivers informed of the current toll rates for various destinations. Importantly, drivers will pay the displayed toll when they enter the Express Lane, irrespective of potential rate changes during their journey. The I-80 corridor will feature four distinct toll zones in each direction, with charges applicable for every toll zone accessed.

Enhancing Transportation Infrastructure

This innovative project is designed not only to bolster the effectiveness of public transport but also to enhance accessibility for emergency services. By optimizing transit routes within Solano County, the Express Lanes are expected to provide significant time savings and reliability for residents and visitors traversing this region. The initiative is specifically beneficial for those traveling toward major destinations such as Sacramento, the Sierra Nevada, San Francisco, and the North Bay Wine Country.

The I-80 Solano County Express Lanes are a collaborative effort between the MTC, Caltrans, and the Solano Transportation Authority, showcasing a commitment to improving transportation infrastructure across the region. The MTC’s Bay Area Infrastructure Financing Authority will oversee operations of the Express Lanes, ensuring they meet the needs of the community effectively.

As of now, the targeted launch date for tolling in mid-December may be subject to change due to adverse weather conditions or any last-minute technical challenges. For anyone interested in utilizing the Express Lanes, comprehensive information on how to access these lanes, find carpool partners, and sign up for a FasTrak account is available at 511.org.

Conclusion

The introduction of the tolling system on the I-80 Solano County Express Lanes signifies a major advancement in the Bay Area’s infrastructure. By facilitating better traffic flow and promoting ride-sharing, these lanes aim to provide a seamless commuting experience that benefits everyone. Residents and travelers alike should be prepared for this exciting new phase in local transportation starting December 16, 2025.
