The Regional Connector Transit Corridor (also known as the Regional Connector, Downtown Connector or Downtown Light-Rail Connector) is an under-development light rail subway corridor through Downtown Los Angeles to connect the Blue and Expo Lines to the current Gold Line and Union Station. The corridor would become part of the Los Angeles County Metro Rail System.
The project is being planned by the Los Angeles County Metropolitan Transportation Authority (Metro). It has been given high priority by Metro in its long-range plan and has funding set aside in Measure R.
The Draft Environmental Impact Report (DEIR) was completed in September 2010 and selection of a preferred alternative was completed in late October 2010. The Final Environmental Impact Report (FEIR) was certified by the Metro Board on April 26, 2012. Pre-construction on the project began in December 2012. The contract for heavy construction on the project was signed on July 9, 2014. Metro hopes to complete construction and begin revenue service by 2020.
The connector was envisioned as early as 1984 when planning and building the Metro Blue Line, and restudied with a through connection in the Pasadena Light Rail Corridor studies in 1990. LACMTA envisioned the Blue Line running through Downtown to Union Station and onward to Pasadena with potential future lines to the northwest (Burbank/Glendale) and to the south and west (Exposition Park/Santa Monica). The connector was not completed due to lack of funds and realignment of the Red Line Eastside Extension, which later became an extension of the Pasadena Gold Line.
The connector was formally studied for the first time as a standalone project in a Major Investment Study in 1992–1993, in preparation of the Long Range Transportation Plan. The project was revived in 2004, when LACMTA staff initiated a technical feasibility assessment for a potential regional connector. This study focused on conceptual methods to provide a regional connector and to alleviate potential operational constraints.
The 2004 staff study looked at the potential alignments that could not be entirely underground, due to funding constraints from the voter-approved 1998 Prop A ban on local county subway funding. Most of the alignments were under Flower Street, surfacing between 5th Street and 1st Street and proceeding east to Alameda Street, connecting to the Eastside light rail corridor (now part of the Metro Gold Line), and continuing either north toward Union Station and Pasadena, or east toward East Los Angeles. Most alignments had stations at the following locations:
LACMTA staff analyzed at-grade street-running couplets, transit mall, elevated and hybrid subway/at-grade/elevated alignments along east-west streets such as Temple Street, First Street, Second Street and Third Street and utilizing available grade-separated infrastructure such as the Second Street Tunnel through Bunker Hill (between Hill and Figueroa Streets) or the Third Street Tunnel (between Hill and Flower Streets) to minimize costs, improve operating times and improve the feasibility of constructing the project.
In July 2006, the LACMTA Board voted to approve funding and staff to initiate a Major Investment Study (MIS) for the Regional Connector in conjunction with approval of a similar study for the extension of the Red Line subway. In June 2007, the LACMTA Board approved the consultants to perform the Alternative Analysis and MIS, and in July 2007 the Alternatives Analysis was initiated. In November 2007, preliminary outreach meetings for the Alternative Analysis were held at Central Library and the Japanese American National Museum (JANM). The results from these meetings were presented to the public in February 2008, including the descriptions of the eight route alternatives identified for analysis, narrowed down to two later in 2008. At the January 2009 Metro Board Meeting, the Regional Connector was approved and received funding to continue in the environmental study process (Draft EIS/EIR).
Environmental review process
The Alternatives Analysis yielded two LRT (light rail) build alternatives, plus the required "No Build" and "TSM" (Transportation System Management) options. A third LRT build alternative was added in February 2010, at the request of Little Tokyo stakeholders (including property, business, and homeowners).
The operational intent of the project is to allow through running of service between the four corridors (Blue Line corridor, Expo corridor, Gold Pasadena corridor, and Gold Eastside corridor). All three build alternatives begin at the 7th St/Metro Center station, which is currently the northern terminus of the Blue Line and the eastern terminus of the Expo Line which opened on April 28, 2012. All three build alternatives connect to the current Gold Line at Alameda Street near Temple Street or 1st Street.
On October 28, 2010, the LACMTA Board of Directors opted for a fully underground option, rejecting at-grade and underground emphasis alternatives. This route remains underground below Flower and 2nd Streets until northwest of 1st/Alameda. By that point, the route would have split into two branches. Each branch would then emerge from a tunnel - one heading north to Union Station, the other east to the Eastside.
Metro added this alignment in February 2010, after receiving public input on the other two options. This option puts the connector underground beneath 1st/Alameda. The fourth new station (at 1st/Alameda southwest block) would replace the existing Little Tokyo/Arts District station. The third station (nearest the Civic Center) was shifted slightly west toward Broadway, in order to take advantage of redevelopment efforts in the historic core. This option is generally fastest and has fewest impacts during operations, but it would have more construction impacts and higher costs.

- FTA cost-effectiveness index (CEI) vs. the TSM alternative.
In September 2010, Metro published the Draft Environmental Impact Statement/Environmental Impact Report (Draft EIS/EIR). The report recommends adoption of the "Fully Underground LRT Alternative" (LRT 3 above).
In October 2010, Metro staff reaffirmed this recommendation, but with the 5th/Flower station removed. The report cites concerns for the overall project cost and the proposed station's short distance from Metro Center/7th Street Station, a mere three blocks, that may not meet FTA funding standards. However, proponents of a 5th/Flower station cite the high density of very large high-rise office buildings within one block of a 5th/Flower station and that such a station would relieve what is expected to be extreme pressure at Metro Center/7th Street (already experiencing pressure) once Expo Line, then Regional Connector are complete.
At the Metro Board meeting in late October 2010, the Board certified the Draft EIS/EIR and accepted the staff recommendation of Fully Underground Alternative with the 5th/Flower station deleted as the Locally Preferred Alternative (LPA). The project staff will now conduct a final study of the LPA, which will culminate in a Final Environmental Impact Study/Environmental Impact Report (Final EIS/EIR).
The purpose of the Regional Connector is to allow rail transit service to run through Downtown Los Angeles. This implies fundamental changes to the Metro Rail lines. Metro has suggested that two lines would replace the current Blue, Expo and Gold Lines: an east-west line along the Expo Line and the Eastside leg of the Gold Line, and a north-south line along the current Blue Line and the Pasadena/Foothill section of the Gold Line.
Early maps show the east-west line in Gold, and the north-south line in Blue. However, Metro has not yet announced how the lines would be renamed. Metro may retain the color-naming system and use the Blue Line designation for the north-south route and the Gold Line designation for the east-west route, or they may decide to go with a different naming system (e.g., letters, numbers, or destinations).
No announcement has been made regarding fare increases, if any are to be made. Currently, a new fare must be purchased every time a passenger transfers from one line to another. The Regional Connector will reduce the number of transfers and therefore reduce income. However, that loss of revenue may be offset by increased ridership.
Pre-construction activities began in December 2012, with the start of the relocation of utility pipes. Major heavy construction was scheduled to begin in 2013, but was delayed by lawsuits, among other factors. As of December 2013[update], utility relocation work continued. The main contractor was finally issued a "Notice to Proceed" in early July 2014.
Most sections of the Regional Connector tunnel will be built using the tunnel boring machine (TBM) construction method, though some sections (especially the locations of the three future rail stations) will be built using the cut-and-cover construction method with an emphasis on maintaining as much road access as possible during construction. Metro has an agreement with The Music Center to use the most advanced noise-suppression measures under 2nd Street where it passes Walt Disney Concert Hall and the Colburn School of Music. This commits Metro to use procedures to ensure that the rumble of trains does not intrude on the sound quality of recordings made in the venues or mar audiences' musical experience within this sensitive stretch of the tunnel.
Two modest, one-story brick buildings had to be demolished since the Little Tokyo/Arts District station will be moved underground and across the street. One of the structures dated back to at least 1898 and for decades both have played an important role in the cultural life of the Little Tokyo neighborhood.
