It began operation during August 2014, but the original Burnet/Manchaca Route 3 remained in service at slightly reduced frequency.

The Pleasant Valley Line will run from Barbara Jordan to Vertex & Slaughter (with a future expansion to Goodnight Ranch Park & Ride) primarily along Pleasant Valley Road, and the Expo Center Line will run from Republic Square to Loyola & Decker (with a future expansion to Travis County Expo Center) primarily along Manor Road.

The southern terminus of route 803 was first shown as shifted to the newly-established Westgate Transit Center (with attached park-and-ride parking lot) on the maps issued in advance of the June 2, 2019 CapMetro service changes.

Stations will be ACC Highland, Clarkson, Hancock, St. David's, UT East, Medical School, Capitol East, Trinity, Downtown Station (where transfer to the Red, Green, or Blue Lines will be possible), Republic Square, Auditorium Shores, SoCo (South Congress), Oltorf, St. Edward's, and South Congress Transit Center.
