US 50 Widening - Phase IV (SHA)
The project proposed construction of a series of improvements along the US 50 corridor between the US 301 Interchange and the MD 404 intersection. These improvements included roadway widening of US 50 from four lanes to six lanes, construction of interchanges and overpasses at selected locations, and construction of service roads to access local residences and businesses.
AMT'S ROLE: AMT prepared P.I. (Preliminary Investigation) plans for a 2-lane service road connection north of and adjacent to US 50 extending from just east of MD 213, off of Grange Hall Road, west to Rustic Acres Lane and Scottown Road. P.I. plans were also prepared for a new grade-separated interchange at US 50 and MD 213 and final right-of-way needs. Additionally, P.I. plans were created for a Park-and-Ride facility adjacent to MD 213 that will accommodate 25 cars. It will have access to MD 213 and to an adjacent service road that runs parallel to US 50 from MD 213 to Rustic Acres Lane. AMT provided PI plans for drainage design and stormwater management which would be used for right-of-way determinations for the widening of US 50 from Bloomingdale Road to east of the MD 213 Interchange (approximately 16,800 feet in length for both the eastbound and westbound lanes), the US 50/MD 213 Interchange, the Service Road, and the Park-and-Ride lot. Maintenance of traffic concept plans for the phasing of the US 50 / MD 213 Interchange work was also prepared.
What Makes this Project Unique? This is a highly visible project to Maryland residents as well as within SHA. The location of the interchange requires a creative approach to developing the Maintenance of Traffic plan so that the traffic flow is not severely impeded, vehicles have a safe traveling route, and the maintenance of traffic cost is minimized. In addition, the interchange has the unique design of having roundabouts placed at the ramp terminals.
