The original Route 1 North Lamar/South Congress bus line – merged from the paired Route 1 North Lamar and Route 13 South Congress lines in 2001 – was the busiest line in the CapMetro system, with peak frequencies of 10 minutes headways Monday through Friday, with wider headways on the weekends. The 101 express line supplemented local service on the 1 line. In 2006, Route 1 was split in two as 1L (serving North Lamar north of Rutland) and 1M (serving Metric), while maintaining high frequencies on the 1L/1M trunk line portion. CapMetro (then branded as Capital Metro) debuted the first MetroRapid service, North Lamar/South Congress (Route 801) on January 26, 2014. It replaced existing
CapMetro Bus Routes 1L/1M and the 101 Express, which traveled along the same corridor. (1M was renamed Route 1 Metric/South Congress, while a local version of the northernmost portion of former route 1L was created as Route 275. The Metric corridor is now served by 325.) Route 801 serves 29 stations between Tech Ridge in North Austin and Southpark Meadows via the
University of Texas and
Downtown Austin. It supplements local service on Route 1, which now has wider headways, resulting in overcrowded buses. A second route, MetroRapid Burnet/South Lamar (Route 803), serves a total of 28 stations between
The Domain and
Westgate. It began operation during August 2014, supplementing service along Route 3 Burnet/Manchaca, which remains in service but now at a slightly reduced frequency. CapMetro expanded MetroRapid started service on February 23, 2025 with two more routes: The Pleasant Valley Line (Route 800) and the Expo Center Line (Route 837). Route 800 runs from Barbara Jordan to Vertex & Slaughter (with a future expansion to Goodnight Ranch Park & Ride) primarily along Pleasant Valley Road, supplementing Routes 7, 300 and 350 on portions of the route. Route 837 runs from Republic Square to Loyola & Decker (with a future expansion to
Travis County Expo Center) primarily along Manor Road and supplementing Routes 20 and 337 on most of the route. ==Operation and Headways==
