The ONT Connector project, officially approved by the San Bernardino County Transportation Authority (SBCTA) Board of Directors on March 5, 2025, is a new transit initiative designed to enhance connectivity and mobility for passengers traveling to and from Ontario International Airport and nearby communities. This innovative underground transit link will connect the Rancho Cucamonga Metrolink Station—a future terminus for the Brightline West high-speed rail and the upcoming West Valley Connector bus rapid transit service—directly to the airport terminals. Operated by Omnitrans, the system will use autonomous, zero-emission vehicles running on demand, aiming to improve transit options, reduce traffic congestion, and support environmental sustainability in the region.
Project Overview and Objectives
The ONT Connector project represents a significant advancement in regional transportation infrastructure, aiming to provide a seamless and efficient transit option between Ontario International Airport and the surrounding transit hubs. By linking the Rancho Cucamonga Metrolink Station, which is slated to become a major transit node with the future Brightline West high-speed rail terminus and the West Valley Connector bus rapid transit service, the project seeks to create a multimodal transportation network that enhances passenger convenience and accessibility.
Technological Features and Environmental Benefits
Central to the ONT Connector’s design is the use of autonomous, zero-emission vehicles, marking a commitment to cutting-edge technology and sustainability. These vehicles will operate underground on demand, providing flexible and frequent service tailored to passenger flow. The zero-emission aspect aligns with broader environmental goals to reduce the region’s carbon footprint and traffic-related pollution, contributing to improved air quality and a reduction in greenhouse gas emissions.
Expected Impact on Transit and Traffic Congestion
The introduction of the ONT Connector is anticipated to alleviate surface traffic congestion around the airport and adjacent communities by offering a reliable alternative to private vehicle use. This initiative is expected to encourage greater public transit ridership through improved first- and last-mile connectivity, ultimately facilitating smoother regional mobility. By integrating with existing and planned transit services, the ONT Connector will support a cohesive network that meets current and future transportation demands.
Administration and Operations
Omnitrans, the regional public transit agency, has been designated to operate the ONT Connector system. With expertise in managing various transit services across San Bernardino County, Omnitrans is well-positioned to ensure efficient and safe operation of the autonomous vehicle fleet. The agency’s involvement underscores a coordinated approach to public transit enhancement within the region.
Next Steps and Timeline
Following the SBCTA Board’s approval, detailed planning, design, and environmental review phases will proceed, with stakeholder engagement playing a key role in the project’s development. Construction timelines and operational launch dates will be communicated as work progresses, with the goal of synchronizing the ONT Connector’s readiness with the opening of Brightline West and the West Valley Connector services to maximize integrated transit connectivity.
In summary, the ONT Connector project represents a strategic investment in sustainable, integrated transportation for San Bernardino County, enhancing access to Ontario International Airport and regional transit hubs. By leveraging autonomous, zero-emission technology and fostering multimodal connections, the initiative aims to reduce congestion, support environmental objectives, and improve overall passenger mobility. As planning advances under Omnitrans’ management, the project is poised to become a key component of the region’s evolving transit infrastructure, aligning with future high-speed rail and bus rapid transit developments to meet growing transportation needs.
