Of the six remaining options for the MidCounty Highway project, also known as M-83, the option preferred by county officials would widen the existing highway—Route 124—from four lanes to five lanes from Goshen Road to Montgomery Village Avenue, according to the report.
Additionally, new roads would be constructed behind Watkins Mill Elementary School and connect with the end of Middlebrook Road near Grassy Knoll Terrace, on the east side of Md. 355, according to The Gazette. Middlebrook Road would be widened to seven lanes between Route 355 and the extension.
