The Metro Gold Line Foothill Extension, an extension of the Los Angeles County Metro Rail Gold Line (light rail) eastward from its current terminus on the east side of Pasadena to the city of Azusa, is in the final design stage. Opening of this extension is scheduled in 2010 and a future extension to Montclair opening in 2014[1]. This segment would be entirely above ground, with a small portion in the median of Interstate 210.

Foothill extention

Phase 2A (Segment 1) and Phase 2B (Segment 2) of the Metro Gold Line Foothill Extension (Phase 1 is the current existing Gold Line from Union Station to Pasadena). San Dimas currently have not picked a station location.

On February 28, 2007, the Metro Gold Line Construction Authority voted to approve the Final Environmental Impact Report, and final FTA project approval is pending[2]; community meetings are being held to gather input on station design and artwork.

No construction funding has been assigned to this project, though funding has been appropriated to continue the design process. Additionally, the construction authority continues to receive operational funding from all of the cities along the proposed alignment. While the extension to Azusa is under the auspices of the construction authority that constructed the Gold Line from Union Station to Pasadena, construction of the other extension from Union Station to East Los Angeles is under the direct control of the LACMTA. The Foothill Extension has strong political support from the governments of multiple cities along its proposed route, while the original segment went through only three jurisdictions (the cities of Los Angeles, South Pasadena and Pasadena). Due to this strong support among the participating cities as well as the area's congressional delegation, eventual construction of the line seems likely, although the project may be pushed back as local Republican congressman David Dreier was the chief supporter of the route for Federal funding. The LACMTA has already purchased the entire right of way needed for this project.

The city of Ontario has joined the group of cities supporting the Gold Line extension citing that the Gold line should make LA/Ontario International Airport its Eastern Terminus, instead of the Montclair Transit station.[3] If all of the proposed extensions were constructed, this would be the longest light rail line in the USA at 51 miles.

Arcadia stationEdit

If Arcadia approves a grade separation and its associated costs (passage of Arcadia's April 11th Measure A Bond has put this option at the forefront), the station will be located southeast of the intersection of North First Avenue and East Santa Clara Street, a short block away from the main commercial area on Huntington Drive. The station would have side platforms, with access from the northwest end of the platforms via the corner of North First Street and East Santa Clara Avenue.

Link to LA/Ontario International AirportEdit

Foothill extension airp

The full Foothill Extension, including the link to the LA/Ontario International Airport that is currently under study. The airport is in green at the right side of the map. There is multiple routes under study, however this map is only showing the general path of the routes.

A 10-month strategic planning study was started in December 2007 to evaluate the extension of the Metro Gold Line from Montclair (where it is currently planned to end) to LA/Ontario International Airport. The study will evaluate the feasibility of connecting the light rail system to the airport, the best routes to consider, potential station locations, the number of riders that would use the system, and much more. These options will be narrowed during the study to identify one or more preferred alignments, and may include stations in Upland, Ontario and Rancho Cucamonga.

The study is in the initial phase. The study team is currently evaluating a number of conceptual routes to connect the Montclair Transcenter (the proposed station location in the city of Montclair) to LA/Ontario International Airport. Under current requirements set forth by the Federal Transit Administration, it can take up to 25 years for a transit project like this to go from inception to completion. This initial study is the first step in this lengthy process.

The study is being undertaken by the Metro Gold Line Foothill Extension Construction Authority Board of Directors and Joint Powers Authority, and is being funded by the Southern California Association of Governments and San Bernardino Associated Governments.

The release of the study report is planned for November 2008.

Airport link routes

The routes identified above are the initial set of options being evaluated in the strategic planning study of the link to the LA/Ontario International Airport. The options will be narrowed to one or more preferred alignments through the course of the 10-month study process.
