Project Connect (listed as Proposition A on the general election ballot) is a transit expansion program by the Capital Metropolitan Transportation Authority (CapMetro) in Austin, Texas, U.S.

Phase I of the Blue Line would operate on a 7.8-mile (12.6 km) stretch of light rail with 13 stations, running through downtown to 38th Street from Yellow Jacket Lane.

Phase I of the Orange Line, planned to be approximately 5.2 miles (8.4 km) with 9 stations, will link North and South Austin.

Additionally, once the new Downtown station is complete, the red line will run every 15 minutes, doubling its current frequency and capacity.

If Project Connect is built out to its full plan in the future, the red line will be electrified,[failed verification] and station platforms will be extended to accommodate 2-unit trains.

[6] The original plans for Project Connect proposed a 1.6-mile (2.6 km) transit tunnel underneath the Downtown area, which would have served the Orange, Blue, and Gold light rail lines.

[9] By 2021, planners were considering moving the Orange Line's southern portal to near Lively Middle School at Leland Street, citing engineering challenges with emerging close to Lady Bird Lake and the topography of South Congress.

CapMetro also chose to buy from two different manufacturers to help compare the performance of each company's buses and inform decisions on larger contracts in the future.

[15][16] CapMetro broke ground in 2019 on a new electric bus charging facility at their North Operations yard on Burnet Road.

[4] Austin Transit Partnership presented five reduced plans in March 2023 in order to deliver the light rail lines with the provided funding.

[4] Austin Transit Partnership selected a preferred route in May 2023 with surface running and one crossing of Lady Bird Lake.

[19] Austin City Council gave its approval to a $7.1 billion preliminary project, which would include 9.8 miles of new light rail line, on June 1, 2023.

[21] The plaintiffs include former state senator Gonzalo Barrientos (D-14), Travis County Commissioner Margaret Gómez (D), and Austin Council Member Ora Houston (D), with the lead plaintiff being a burger restaurant built in 1926 named Dirty Martin's that was set to be demolished in the original project proposition.

[22] More specifically, the plaintiffs argue that the city cannot use money that was earmarked for maintenance and operation to be used for debt service on bonds the ATP planned on issuing.

[24] House Bill 3899 was introduced by Ellen Troxclair (R-19), a former member of the Austin City Council, which would have frozen the project until a new referendum could be held.

[27] The Austin Transit Partnership has estimated it will spend $116 million towards "professional services and administrative costs" with the rest going towards new construction.
