The Capital District Transportation Authority (CDTA) is a New York State public-benefit corporation overseeing a number of multi-modal parts of public transportation in the Capital District of New York State (Albany, Montgomery, Rensselaer, Saratoga, Schenectady, Warren, and Washington counties).

Created as an act of the New York State Legislature in August 1970, CDTA was formed similarly to agencies in Syracuse, Rochester, and Buffalo.

CDTA bus operators, dispatchers, and supervisory staff are organized in Local 1321 of the Amalgamated Transit Union (ATU).

In early 2011, CDTA announced its plans to restructure the Albany County bus routes in two phases.

Phase 1 involved reconstructing routes within the city of Albany, with a public input campaign held until August 2011.

Phase 2 involved reconstructing routes within the western and northern portions of Albany County, with a public input campaign held until September 2012.

Before July 2007, the Saratoga Springs buses were operated from the Uncle Sam Depot at 40 Hoosick Street in Troy, with limited service.

CDTA plans to eventually construct a Saratoga Springs bus garage at Grande Industrial Park, off of Geyser Rd.

Madison & Green Does not serve downtown troy after 7:30 pm, ends at HVCC 15th St. & Park Blvd Formerly Greater Glens Falls Transit until CDTA took over operations on January 1, 2024.

Route #155 operates between Albany International Airport, ITT Tech, NY 155, Washington Ave Ext., Walmart, and Crossgates Mall.

Queue jumping and signal priority were planned to make BRT more attractive to the region, after light rail was rejected.

In early 2008, CDTA announced that it was going forward with the bus rapid transit line on NY 5, which included 19 upgraded stations.

[75] NY 5 BRT service began on Monday, April 4, 2011, with new silver and red-branded Gillig 40-foot hybrid buses, numbered Route 905 and referred to as BusPlus.

In cooperation with the Saratoga Chamber of Commerce, CDTA operates open-air trolleys during the summer months.

Though for most of its history it has been dominated by the Orion II low-floor minibus, STAR has begun replacing older models with Startrans "Senator" cutaway vehicles.

These routes run from Saratoga Springs, Ballston Spa, Malta, Clifton Park, Round Lake, and South Glens Falls to Downtown Albany.

[76][77][78] At first the service was free, but in October 2020, CDTA started requiring riders to pay for Flex ride.
