The Deanwood–Minnesota Avenue Line, designated Route U7, is a daily bus route operated by the Washington Metropolitan Area Transit Authority between Deanwood station and Minnesota Avenue station of the Orange Line of the Washington Metro.

During WMATA's Fiscal Year of 2015, they announced a series of proposals of simplification affecting the current routes U2, U4, U5, U6, U8, V7, V8, and V9.

[2] For route U4, it goes as the following:[2] This rerouting was to create a better balance of capacity and demand on lines serving the Minnesota Avenue station.

The changes were to retain direct connections between Mayfair and Parkside, Minnesota Ave station, and the Minnesota Avenue shopping corridor during the primary shopping hours and to improve productivity by rerouting and extending Route U7 to serve moderate to high density residential and commercial corridors as route U7 only have service along the Kenilworth Avenue service road.

[8] During the COVID-19 pandemic, Route U7 was reduced to operate on its Saturday supplemental schedule during the weekdays beginning on March 16, 2020.

[12] In February 2021, during the FY2022 budget, WMATA proposed to eliminate the U7 section between Deanwood station and Greenway due to low federal funding.
