83 is shortened to only operate on short trips between Rhode Island Avenue station and Mount Rainier during early mornings on the weekends.

83 & 86 mainly operate on the U.S. Route 1 corridor between Rhode Island Avenue in Northeast Washington, D.C. & College Park, Maryland.

The 83 is shortened to operate daily between Rhode Island Avenue station and Mount Rainier terminal only during early mornings on the weekends.

Select Route 83 trips operate between Rhode Island and College Park during Friday and Saturday late nights only.

Additionally, route 86 would remain straight along Rhode Island Avenue with no service to Hyattsville Crossing station.

84 eventually stopped operating as part of the Maryland Line on December 3, 1978, when it got split off into its own separate Metrobus Route named the, "Rhode Island Avenue - New Carrollton Line", due to being rerouted to operate between the Rhode Island Avenue and New Carrollton Metro Stations.

On February 19, 1978, 83 was created as a brand new Metrobus Route to operate parallel to 82 between Potomac Park and Hollywood, only with exception of making limited stops to provide a speedier trip during weekday rush hour/peak period times.

During the time that this particular rerouting change took place, 82 and 83's former Hollywood Loop north of Rhode Island Avenue and Edgewood Road in College Park was eliminated.

On December 11, 1993, when the Green Line extension Greenbelt opened, Route 82 was truncated to only operate on short trips between the Rhode Island Avenue station and Mount Rainier during early morning, late night, and PM rush hours only eliminating service to Cherry Hill.

[10] Route 86 was also rerouted off Belcrest Road in order to serve the newly opened Prince George's Plaza (now Hyattsville Crossing) station.

[12] On May 15, 2003, the original bus bays at Prince George's Plaza Shopping Center were closed to build a new Target store.

[14][15] Due to the construction of a new curb next to the new Mosaic Apartments built right next to Prince George's Plaza (now Hyattsville Crossing) station around May/June, 2007, all Metrobus Routes that have previously exited Prince George's Plaza (now Hyattsville Crossing) station from the northbound side, had to do so by exiting the Prince George's Plaza (now Hyattsville Crossing) station via a right turn onto East-West Highway and left onto Belcrest Road.

On August 25, 2011, WMATA added a new route to the College Park Line called "83X" as a pilot route during the summer in order to provide additional direct service from Cherry Hill Campground to College Park–U of MD station operating four weekdays trips only from 8:30 am to 10:00 am only from the third Monday in June through the second Friday through August.

All existing service would still be covered but passengers will have to transfer at College Park station in order to continue their trips.

[21] Short trips between Rhode Island Avenue station and Mount Rainier were made 83 routes instead during late nights and early mornings.

Also, due to Metro closing at midnight during that time period because of SafeTrack maintenance, select Route 83 trips were introduced to operate between Rhode Island Avenue–Brentwood and College Park–U of MD station on Friday and Saturday late nights only.

[28] In May 2020, WMATA announced that route 83X will not operate during for the 2020 summer season due to the ongoing COVID-19 pandemic and Metro's reduced service since March 16, 2020.
