Alternate 7 (Enhanced)

The relocation of MD 28 begins at the MD 115 (Muncaster Mill Road) intersection, incorporates a horizontal reverse curve, to avoid impacts to the convenience center, crosses under MD 97 approximately 700’ north of existing MD 28, reconnects to existing Norbeck Road near Coolidge Avenue and ends just past Bradford Road. At the existing MD 28/MD 97 intersection, the median crossover and traffic signal would be eliminated. Access to and from MD 97 to Relocated MD 28 is accomplished via right-in/right-out connector ramps that utilize much of the existing MD 28 right-of-way.

At MD 28 west of MD 97, a split ‘T’ configuration is utilized. One ‘T’ intersection serves existing MD 115 and the other serves the west side connector ramps (See attached map). At MD 115, the existing concrete median would be removed and an additional northbound lane would be provided to accommodate the double right-turn. Following the public hearing, it was decided to leave the fourth leg open at MD 115 intersection providing access to the service road.

MD 97 would have three through lanes in each direction, and the median will be reserved for a future busway. The Thistlebridge Drive connection to MD 97 remains the same as today. A two-lane connector is also provided between Relocated MD 28 and Thistlebridge Drive, to improve access from the east. A right in connector has also been provided from Relocated MD 28 to the convenience center.

To accommodate bike commuter traffic, additional width would be included in the outermost thru lanes of Relocated MD 28 and MD 97. The existing bikeway on MD 655 north of Thistlebridge Drive would also be extended south to the hardware store parking lot.
