Avia is currently comprised of five colour coded routes. All terminate at Bristol Castle Park
Blue line services run from the centre of Bristol to Bradley Stoke and Cribbs Causeway, before doubling back and terminating at Temple Meads. The line operates at a ten minute frequency during daytime hours, meaning that there is a combined Blue line tram every 5 minutes along the core section between Temple Meads and Parkway.

Yellow line services run from Siston Hill on the eastern edge of the conurbation, via the former Midland Railway alignment through Staple Hill and Fishponds to Lawrence Hill and the City centre. During Peak hours, trams operate every 5 minutes along the route, with half terminating at Temple Meads
Maroon line services run from Parson Street station via Ashton Gate Park and Ride to the City centre via Cumberland Road and St Mary Redcliffe. The line is the shortest route of the five, although future plans could see the route extended out to Hengrove Park and Hartcliffe. Much of the Maroon route utilises the route of the Nineteenth centuryBristol Harbour Railway
Pink line services operate every 10 minutes during peak periods from Portishead to the city centre. Services to Portishead share the route between Ashton Avenue Bridge and Temple Circus with Maroon line trams.
