The Inland Rail Trail is a proposed 21-mile Class I facility that is located within the communities of Oceanside, Vista, San Marcos, and Escondido, as well as within a portion of the unincorporated County of San Diego.

The eastern most portion of the bikeway already has been constructed by the cities of Escondido and San Marcos and extends from the Escondido Transit and SPRINTER Rail Station in the City of Escondido to the intersection of West Mission Road and North Pacific Street in the City of San Marcos.

The current project, the San Marcos to Vista portion of the Inland Rail Trail, is a 7-mile section of Class I bikeway and multi-use path in San Marcos, Vista, and the County of San Diego. The project extends from the intersection of West Mission Road and North Pacific Street in San Marcos, where the existing trail ends, to the intersection of North Melrose Drive and West Bobier Drive & Oceanside Boulevard, at the Vista Oceanside boundary, and near the North Melrose SPRINTER station. Construction of the San Marcos segment was completed in November, 2016. Construction of the next phase, which includes the County segment and two segments in Vista from the southeasterly city limit to Mar Vista Drive and from North Drive to N. Melrose Drive and Oceanside Boulevard, started in June 2017. Work in Vista near Phillips Street and Mar Vista Drive (Phase 3A) began in January 2018.  SANDAG has secured a $5.6 million grant for the next phase of the project (Phase 3B) in Vista, from Mar Vista Drive to Civic Center Drive, in September, 2017.
