Indianapolis had a
streetcar system that was established in 1854 and operated by various private companies until it was consolidated under the Indianapolis Street Railway Company in 1899 and later Indianapolis Railways in 1932. The final streetcar ran on January 10, 1953, and was replaced by a system of
trolleybuses that operated from 1946 to 1957. Streetcar operator Indianapolis Transit System transitioned to motor coaches that followed the same routes as used by the streetcars. The
city of Indianapolis took over public transportation in 1975 and established the Indianapolis Public Transportation Corporation to administer bus services. The corporation originally operated buses under the name Metro Bus; the IndyGo name was adopted on November 11, 1996. Portions of the system were briefly
privatized in the 1990s, but the move proved unpopular, and all operations were ultimately taken over by the city. IndyGo has seen a near-constant trend of decreasing ridership since the 1970s and continues to explore options for revitalization. "Express" bus routes were used in the 1980s as an attempt to gain more middle-class riders from outlying areas, but the routes were largely discontinued by the early 2000s. The Blue Line downtown circulator route was added in 2005 to attract passengers and saw considerable ridership. In late 2006, IndyGo complemented the Blue Line with the introduction of the Red Line, which ran between the
Indiana University–Purdue University Indianapolis campus and downtown with 15-minute frequency. The Blue Line's ridership declined as federal funding allotted for the route ran out, and the route was discontinued after December 31, 2007. The Red Line remained a free route until January 2009, at which time it became a regularly priced route. The Red Line was retired when the Downtown Transit Center opened, with IUPUI service being covered by Routes 3, 10, and 37, along with 15-minute frequency on Michigan and New York streets. In the fall of 2007, IndyGo introduced an express route operated by a contractor, using
ADA-accessible MCI J4500 motor coaches. The route ran from downtown to the northern suburb of
Fishers in
Hamilton County, the most populous suburban county of Indianapolis. In March 2008, an additional express route to
Carmel (also in Hamilton County) was launched, followed in March 2009 by express service to
Greenwood, a southern suburb in
Johnson County. These ICE Express Routes to Greenwood, Fishers, and Carmel were discontinued in 2010 after their federal grants expired. The Green Line, an express bus between downtown and
Indianapolis International Airport, was also begun in 2007. It ceased operation on September 16, 2012, due to the expiration of the federal grant funding it, leaving local Route 8 to serve the airport.
Marion County Transit Plan , in September 2019. Indy Connect is a $1.2 billion plan to create a network of
bus rapid transit lines, bikeways, and walkways. In 2017,
City-County Council approved a voter referendum increasing Marion County's income tax to help fund IndyGo's first major system expansion since its 1975 founding. Local taxes and federal grants are funding systemwide improvements, including the creation of three
bus rapid transit lines, battery electric buses, sidewalks, bus shelters, extended hours, and weekend schedules. The first segment to be constructed is phase one of the
Red Line, traveling from Broad Ripple Avenue to the
University of Indianapolis. Construction along the route began in June 2018 and the route opened on September 1, 2019. In February 2020, the corporation announced it would be canceling an order for five battery-powered coaches for Route 39 along East 38th Street due to reliability issues with the
BYD vehicles. IndyGo stated in a press release that the company had not met its contract which required the buses to cover until recharging, nor did it provide a permanent enroute re-charging solution. The existing BYD vehicles have been moved to the Red Line, requiring a new $7.5 million contract for 13
Gillig diesel vehicles for Route 39. In March 2020, the
Indiana General Assembly debated a 10% public funding cut for IndyGo, after lawmakers claimed that the corporation was not engaging with 2015 legislation which required it to seek up to 10% of its budget through private funding. Legislators have proposed withholding income tax money and preventing expansion routes until IndyGo meets its 10% funding goal. However, IndyGo CEO Inez Evans responded that the corporation had been unable to officially meet the target due to delays in establishing its foundation, which recently received $35,000 in private investment, and stated that public funding cuts could jeopardize its transit plans. In April 2020, IndyGo postponed system-wide route changes as part of the Marion County Transit Plan implementation due to the
COVID-19 pandemic. The changes would have switched the current
hub-and-spoke system to a grid network that would allow for easier transfers across the city. In August 2020, IndyGo initiated a "bus stop balancing" project to eliminate or consolidate 524 redundant or lightly used boarding bus stops and create 45 new bus stops. Construction began on IndyGo's second bus rapid transit project, the
Purple Line, on February 25, 2022. It opened to the public on October 13, 2024, with service primarily on 38th Street between downtown and
Lawrence to the northeast. Since November 2024, the Purple Line has had the highest monthly ridership in the IndyGo system and reached 100,000 monthly passengers in April 2025. Groundbreaking on the Blue Line, the third and final bus rapid transit project from
Cumberland in the east to the
Indianapolis International Airport west of downtown, took place on February 28, 2025, with construction anticipated to conclude in 2028. The Blue Line's use of dedicated bus lanes has been criticized by some state legislators, who introduced a bill in 2024 to ban them. The bill was dropped after IndyGo and the city government agreed to maintain two lanes in each direction for general purpose traffic in more sections of the route.
Julia M. Carson Transit Center The
Julia M. Carson Transit Center at 201 E. Washington Street serves routes that transit downtown Indianapolis. Ground was broken for the $26.5 million facility in September 2014. A ribbon-cutting ceremony was held on June 21, 2016, with formal bus service beginning on June 26, 2016. In addition to IndyGo's Customer Service Retail Center, the center includes free Wi-Fi, public restrooms, a conference room, administrative offices, bus operator lounge, seating, real-time arrival and departure information, 19 bus bays, and of retail space. Of IndyGo's 31 routes, 26 routes offer transfers at the station. The transit center is named for
Julia Carson, former
U.S. Representative for
Indiana's 7th congressional district (1997–2007). During her tenure in Congress, Carson helped secure federal funding for the $26.5 million transit center. == Routes ==
