Former routes
Chittenden County routes
On June 17, 2019, GMT converted all the previously-numbered routes to colored through-routed (via the DTC) services. A short time thereafter, due to passenger feedback, GMT added the route numbers back in with the color scheme. The Red Line was composed of the 7 and 1 routes, the Blue Line with the 6 and 2, the Green Line with the 5 and 9 and the Orange Line with the 10 (and the later addition of the 4, which was originally the Silver Loop after conversion). The 8 became the Gold Loop. On June 14, 2021, due to more customer feedback, the GMT eliminated the color designations in favor of the previous numerical ones.
