The Metro Green Line (formerly called the Central Corridor) is an light rail line that connects the central business districts of Minneapolis and Saint Paul in the U.S. state of Minnesota as well as the University of Minnesota. An extension is under construction that will extend the line to the southwest connecting St. Louis Park, Hopkins, Minnetonka and Eden Prairie. The line follows the path of former Metro Transit bus route 16 along University Avenue and Washington Avenue (which runs from downtown Minneapolis through the University of Minnesota main campus). It is the second light-rail line in the region, after the Blue Line, which opened in 2004 and connects Minneapolis with the southern suburb of Bloomington.

Construction on the Green Line began in late 2010. It opened to the public on June 14, 2014. The travel time between the downtown Minneapolis and downtown St. Paul stops is about 46 minutes. The entire line originally operated 24 hours a day, seven days a week, but as of 2019 trains are replaced by buses from 2 am to 4 am on weekdays. In 2018, the line carried a total of 13.8 million passengers.

History

Former streetcar and bus lines The route is a descendant of the Twin City Rapid Transit Company's St. Paul–Minneapolis streetcar line, also referred to as the Interurban line. Streetcars became practical along the route with the advent of electrification, and full service began along the route on December 9, 1890. In the 1950s, a decision was made to convert the streetcar system to buses. Streetcar service along the Interurban line ended in Saint Paul on October 31, 1953, and the route was the last to carry passengers in the city. Service continued a short while longer in Minneapolis, until November 28.Olson. p. 65. However, due to fragmentary service elsewhere in Minneapolis, streetcars continued to use the tracks along University Avenue to reach the shops at Snelling Avenue in Saint Paul until June 1954.

The route 16 bus was developed to replace the streetcar, and followed the route of the modern-day Green Line. Other parallel service included freeway express service on route 94 and limited-stop service to the University of Minnesota on route 50. Twin City Lines continued to privately operate buses until 1970, when the company was taken over by the Metropolitan Transit Commission, a precursor to Metro Transit.

Proposals In 1972, the Regional Fixed Guideway Study for the Metropolitan Transit Commission (the forerunner of today's Metro Transit) proposed a $1.3 billion 37- or 57-mile (sources differ) heavy-rail rapid transit system, but the then-separate Metropolitan Council disagreed with that idea – refusing to even look at the plan – and continuing political battles meant that it was never implemented. The Met Council had its own plans for bus rapid transit in the metropolitan region. Another system using smaller people movers was proposed in the 1975 Small Vehicle Fixed Guideway Study and gained the most traction with the Saint Paul city council, but was eventually dropped in 1980.

In the 1980s, light rail was proposed as an alternative and several possible corridors were identified, including the Central Corridor line which had a Draft Environmental Impact Statement (DEIS) drawn up in 1982. It took another two decades before the Blue Line light rail line began operation. It began service on June 26, 2004, just over 50 years since the last regular-service streetcar ran on June 19, 1954.

Central Corridor Coordinating Committee The Central Corridor Coordinating Committee was a workgroup in the Minneapolis-St. Paul area set up to explore transit options for the Central Corridor, the interurban corridor roughly following University Avenue in the Twin Cities area. After a long period of examination, this committee narrowed transit options for the corridor from a broad universe of choices to just three: a no-build option where services are only incrementally improved, a bus rapid transit (BRT) option, wherein buses run on semi-dedicated transitway, and a light rail transit (LRT) option using light rail vehicles (LRVs). In May 2006 the CCCC concluded its study by publishing a Draft Environmental Impact Study, which concluded that LRT was the best option for the corridor. After a period of public meetings and public comment, the CCCC recommended on June 6, 2006, that the Metropolitan Council select LRT as the locally preferred alternative for the corridor and apply for preliminary engineering to begin. On June 28, 2006, the Metropolitan Council concurred with the CCCC's decision and officially selected LRT as the locally preferred alternative.

Metropolitan Council manages all transit, waterway, and other public resources for the seven-county area surrounding the Twin Cities, and as such, the Central Corridor project will now transition to Metropolitan Council. The work of the Central Corridor Coordinating Committee is now complete.

Funding A 2003 study commissioned by the Central Corridor Coordinating Committee placed the cost at US$840 million. Cost estimates placed the cost of the light rail line in 2003, at about US$957 million, with the increase primarily due to inflation over the following decade. On June 6, 2006, the light rail option was endorsed by the Central Corridor Coordinating Committee. The Metropolitan Council gave final approval to this decision on June 28, 2006.

The existing Blue Line has exceeded ridership predictions, as is the case with many other light rail lines constructed in the U.S. during the last decade. This led to some delays for the Central Corridor project because local transit officials were forced to retool ridership models before submitting projections to the Federal Transit Administration (FTA). The Metropolitan Council, which operates Metro Transit, submitted numbers showing that a light rail line would carry 43,000 passengers daily by the year 2030. The FTA agreed that the line would be cost-effective at this level, a key requirement for obtaining federal funding.

In April 2008, Governor Tim Pawlenty initially vetoed $70 million in funding for the Central Corridor project, along with other items, from the state budget. The funding was part of a state-local package of $227 million necessary to get federal transportation funds, and the future of the project was in doubt until May 18, 2008, when a revised bonding bill including the $70 million for the Central Corridor was passed in the Legislature and signed into law by the governor. In August 2009 the Central Corridor project received a Record of Decision from the Federal Transit Administration. The FTA found the project to have fully and accurately completed its environmental documentation with the publication of the Final Environmental Impact statement earlier in the summer, thus clearing the project for final design.

Construction

The first construction began in late 2010, including work in downtown St. Paul and near the University of Minnesota campus. By November 2011, construction was about 32% complete, including most heavy construction such as the installation of track segments, a new bridge, partial completion of stations, a rebuilt skyway in St. Paul and the construction of Green Line facilities at St. Paul Union Station.

Due to the scope of the project, a venture was created by C.S. McCrossan and Ames to complete an area known as The Civil West Project. This area extended from the west side of the 35W abutment, over the Mississippi River, through the UofM campus and ending at Bedford St. From Bedford to Saint Paul, Walsh Construction served as the general contractor.

In July 2011, the Metropolitan Council officially named the Central Corridor as the Green Line. As of August 2013, construction was completed and test trains began running over the line which opened to the public on June 14, 2014.

Additional stations

Some in favor of the line have expressed concern with the number of stations. The neighborhoods along University have demanded that the line have stations every half-mile, from Snelling to Rice Street, which would mean stations at Hamline Avenue, Victoria Street and Western Avenue. In February 2008, the Central Corridor Management Committee passed a resolution to include below-ground infrastructure for the Hamline, Victoria and Western stations "with the understanding that, if the CEI increases or other dollars are made available by mid-summer 2008, the first claim on those dollars would be one of the infill stations." The Metropolitan Council has included this infrastructure work in their Draft Environmental Impact Statement and has also committed to building one station if any funds become available.

As of 2009, the Federal Transit Administration has increased the Cost Effectiveness Index such that buildout of one station is now feasible. On January 25, 2010, the FTA announced that the three "infill" stations will be built. Upon opening, all five stations between Snelling and Rice Street were built - Hamline Ave, Lexington Pkwy, Victoria St, Dale St, and Western Ave.

Opposition

Many businesses along the line were opposed to its development because of reduced access for automobiles. Under the final plans, 87% of on-street parking disappeared along University Avenue between Raymond Avenue and Rice Street. At least one restaurant has cited light rail construction as a reason for closing.

The corridor contains working-class residents and immigrant populations from Laos and Vietnam. Although the Green Line construction is mostly on an existing roadway and no land will be condemned, the disruption to existing transit and pedestrian ways was a concern to some groups. There is also concern that stops for light rail will be placed too far apart and along with reductions in bus service, transportation options for people will be reduced. Others are concerned about gentrification, where rising property values and taxes could force out lower-income residents.

Others have opposed using Washington Avenue for a pedestrian transit mall and have opposed using the Washington Avenue bridge, citing traffic concerns, along with the age of the bridge, when other bridges upriver could be used to cross the Mississippi River: the 10th Avenue Bridge, the new I-35W bridge or the Northern Pacific Bridge Number 9. This last option was preferred by the University of Minnesota, which feared traffic disruption and vibration at some of their research facilities from use of the Washington Avenue route. In late summer 2008, preliminary engineering reports showed that mitigation work could negate the effects of vibrations on university laboratory equipment. The University of Minnesota renewed its objections over vibration concerns along Washington Avenue in late 2009. Negotiations between the Metropolitan Council and the university continued into early 2010. A compromise was reached between the university and the Metropolitan Council and the Washington Avenue bridge was selected for use. As of Summer 2011, work had begun on the Washington Avenue bridge.
