via Brightseat Road and Ardwick Industrial Park and discontinuing service to Capital Plaza and Landover station primarily running along Martin Luther King Jr. Highway. A new Route L12 will operate the A12 routing between Capital Plaza and Largo Town Center (now ) station via Landover station and Woodmore Town Center primarily running on Landover Road via Palmer Park and Hawthorne Street running along the old A12 routing. Stops between Martin Luther King Jr. Highway and Brightseat Road will be replaced by a rerouted route F14 which will discontinue service along a portion of Brightseat Road being replaced by Route A12.
The reason for the changes was that WMATA wanted to have one route running primarily along Martin Luther King Jr. Highway (A12) and another route running primarily on Landover Road (L12). However public feedback was opposed to the route change, which led WMATA to shelve the plans.
Later during WMATA's 2024 Fiscal Year Budget in March 2023, WMATA brought back the A12 and L12 proposal from 2014, which was almost identical to the original proposal. However one difference was route F14 would not be rerouted along Landover Road and instead remain on Brightest Road. Subsequently, the FY2024 budget was approved in April 2023, which included a new Route L12.
In June 2023, WMATA announced the new L12 will begin service on June 25, 2023. The line would be named under the Landover Road Line and will operate every 20 minutes between
