Transit Authority of River City

TARC was created in 1971 after 1970 legislation authorized city and county governments to operate mass-transit systems with local funding. At the time, public transit was provided in Louisville by the private Louisville Transit Company. The company had long operated mass-transit lines in the city, converting from electric trolleys to diesel buses in the late 1940s and changing its name from the Louisville Railway to the Louisville Transit Company in 1947.

Following a trend in cities across the United States, the company saw annual ridership decline from 84 million in 1920 to 14 million in 1970. Its ridership was no longer large enough to cover operating expenses, and in 1971 it posted its first loss. In 1972, the company announced that it would cease operations on September 1, 1974.

The local government began subsidizing fares in July 1973, but this was not enough to make the Louisville Transit Company profitable. Bridge Transit Company (which provided mass transit between Louisville and Jeffersonville) ceased operations at around the same time due to lack of revenue, setting the stage for a metropolitan area without any private mass-transit companies.

Voters approved a controversial 1974 referendum, supported by Mayor Harvey Sloane, which approved an increased occupational tax to fund mass transit. Combined with a federal grant, this was enough for TARC to purchase the Louisville Transit Company, buy new buses, reduce fares, and create new service lines. TARC bought up the area's remaining mass-transit companies: Blue Motor Coach Lines (which served outlying areas) in 1976, and the Daisy Line (connecting New Albany and Louisville) in 1983.

In 1993, TARC experimented with water-taxi service connecting the Belle of Louisville wharf and Towboat Annie's Restaurant in Jeffersonville. A feasibility study for a light rail system in the Louisville area was funded by TARC in 1996 and proposed a north–south route that followed the Interstate 65 corridor that was adopted in 1998. The project's draft environmental impact statement was submitted to the Federal Transit Administration, but was not recommended for final design due to a lack of clear state or local funding for the $661 million cost. TARC paused its planning and engineering work on the light rail line in May 2004.

In February 1994, an audit committee headed by Bruce Lunsford found that TARC had been mismanaging funds and was depleting its once-large trust fund with increasing expenses such as door-to-door service for the disabled and spending on personal services and fringe benefits for administrators which was higher than that of transit companies in similarly sized cities. TARC's executive director resigned after the audit, and fares nearly doubled before the end of the year. In August 2011, TARC's new $4.5 million, 17,700-square-foot Maintenance and Training Annex received a Gold LEED (Leadership in Energy and Environmental Design) Certification.

TARC began to purchase hybrid buses in 2004, and began purchasing ultra-low-sulfur diesel buses by 2008; by late winter 2012–2013, the company added 16 ULSD buses. Eleven hybrids were added by midsummer 2013, bringing TARC's hybrid total to 32. The company added 21 ULSD buses that fall, and 12 more the following fall; some are equipped with WiFi. Thirteen more updated buses were due to arrive by late 2016, increasing the company's ULSD fleet to 95. Electric buses began operation in downtown Louisville in early 2015 and, according to the Courier Journal, share the 8th Street charging station with a trolley route. There is another charging station in downtown Louisville, at 3rd and York Streets. The 30-passenger buses can operate for up to two hours on a charge and, like the old trolleys, are fare-free. On November 5, 2019, TARC observed its 45th anniversary; since 2016, the company has added 45 ULSD buses and one hybrid. On January 6, 2020, TARC introduced Kentucky's first bus rapid transit line.

TARC purchased and took delivery of 72 clean diesel buses during FY 2022. TARC purchased 8 more electric buses that were expected to be delivered in the fourth quarter of FY 2024. These 80 buses were to replace 80 older buses that had been in service since the mid-2000s. The agency launched an updated real-time locator system for its buses in 2025 alongside upgrades to on-board passenger information screens with audio and visual announcements. The TARC network underwent a major restructuring in August 2026 that decreased the number of routes from 24 to 15 and cut nearly half of its 3,300 bus stops. The plan was enacted in response to budget issues and low ridership. A new Downtown Transfer Center at Muhammad Ali Boulevard and 8th Street opened along with the new routes, which were designed to allow for "pulsed" transfers. Under the new network, most routes have frequencies of every 15 to 30 minutes.

Services

TARC operates buses which serve the Louisville area. The TARC network has 1,430 bus stops. The stops are served by 15 routes. The daily routes are named for the primary road on which they run.

Since 1999, it has operated a shuttle service for the University of Louisville's main campus. The company operates two routes shuttling workers to Worldport, the hub of United Parcel Service and one of Louisville's largest employers. TARC launched a "Ride to Safety" program in 2007, which allows domestic abuse victims to use its buses for transportation to a shelter.

TARC and its predecessor had provided shuttle access to the Kentucky Derby and Kentucky Oaks since the 1950s, but in 2008 new federal rules required Churchill Downs to negotiate with private companies for service. The shuttle operation transported tens of thousands of people each year and provided TARC with over $200,000 of annual revenue. TARC provides service to other local events, including Thunder Over Louisville and the Kentucky State Fair.

It began a "Bikes on Board" program in 2001, and two-to-three-bicycle bike racks had been installed on all its full-size buses by 2004. In 2005, TARC reported that an average of 6,000 riders a month used the bike racks.
