(December 26, 2017) – The Maryland Department of Transportation State Highway Administration (MDOT SHA) has opened the MD 147 (Harford Road)/Glen Arm Road/Mt. Vista Road roundabout in northeastern Baltimore County. Crews will return spring 2018 when temperatures are warmer to complete final paving, which will take approximately one week.
The roundabout will significantly improve safety by slowing travel speeds and reducing potential left turn crashes at the intersection, as well as improve traffic flow by providing a continuous flow of traffic. MDOT SHA appreciates the patience of residents and motorists who reside in the project area and those who use Mt. Vista and Glen Arms Roads in Baltimore County.
The $3.7 million roundabout project, which began fall 2016, necessitated temporary phased closures and detours of Mt. Vista Road and Glen Arm Road throughout the duration of the project. Harford Road, which has an average daily traffic volume of 6,000 vehicles, was not closed during construction. MDOT SHA has built dozens of roundabouts at intersections across Maryland over the last 25 years, eliminating intersection-related fatal crashes.
