Route X9 originally operated as part of the East Capitol Street Express Line which operated alongside the Benning Road Line with routes X1, X2, X3, X4, X5, X6, and X7.[1] Route X9 originally operated between Capitol Heights station and Federal Triangle but was discontinued in the late 1980s and replaced by the Benning Road Line.

In 2010, WMATA released a study along the H Street and Benning Road corridor. As ridership increases along the corridor and consistent delays on the DC Streetcar, WMATA proposed a brand new route X9 to operate between Capitol Heights station and Metro Center station. This was to reduce crowding during the weekday peak-hours and to replace route X3.[2][3][4]

On December 19, 2010, route X9 was introduce as a new express bus route to primarily operate along H Street, Benning Road and Nannie Helen Burroughs Avenue. This new route will operate during the weekday peak-hours between Capitol Heights station and Metro Center station. The new X9 will supplement route U2 between Capitol Heights and Minnesota Avenue station and route X2 between Minnesota Avenue and Metro Center.[5][6]

In June 2012, WMATA announced that the "express" brand for Metro will be renamed into the MetroExtra brand. Route X9 was slowly converted into the MetroExtra brand in the fall of 2012. There were no major changes to the routing.[7]

On September 26, 2017, as part of WMATA's FY2018 budget, WMATA proposed to add midday service to route X9. This proposed was in part to customer demand and requests and jurisdictional coordination and responds to requests by the District Department of Transportation. Route X9 will provides additional limited-stop capacity to accommodate new riders in the Benning Road-H Street corridor during the weekday midday to help route X2 and provide a weekday midday transfer-free ride throughout the entire corridor on proposed Route X9 between downtown DC and Capitol Heights station. This proposal was also recommended in the 2010 Benning Road-H Street Lines Service Evaluation Study.[8][9]

On June 24, 2018, route X9 was given new weekday midday service which will operate every 15 minutes between Minnesota Avenue station and Metro Center station. Differences in the routing was route X9 will enter the Minnesota Avenue bus bays during the midday hours while during weekday peak-hours, the route would serve the on-street bus stop at Minnesota Avenue.[10][11]

Route X9 was suspended during the COVID-19 pandemic on March 16, 2020.[12] However the route returned to service on August 24, 2020.[13]

In February 2021 during the FY2022 budget, WMATA proposed to eliminate the X9 portion between Minnesota Avenue and Capitol Heights station if WMATA does not get any federal funding.[14]

On December 11, 2022, all westbound X9 trips was shortened to terminate at Gallery Place station.[15]
