The roadway will be a four lane divided highway. Design elements include:

  • Two 12′ lanes in each direction
  • 4′ inside and 10′ outside shoulders in each direction
  • Intersections designed to eliminate through movements and left turns from side streets, driveways, and access roads. J-Turns, which require vehicles to make a right turn onto MD 404 and then a U-turn at a median crossover, will be provided to improve roadway safety.
  • Partial acceleration/deceleration lanes are proposed at major intersections
  • Linear swales and stormwater ponds to address water quality and quantity requirements
  • One bridge over Norwich Creek and multiple culverts and small structures
  • The wider roadway will improve safety and operations and reduce traffic congestion caused by high seasonal peaks associated with summer resort traffic

Environmental Issues

As with all construction, protecting the environment is paramount. Along the MD 404 Corridor, wetlands and a federally endangered dwarf wedge mussel are top environmental preservation priorities. To protect the mussel, construction work cannot occur within at least 25 ft of the Norwich Creek and no “in stream” work is allowed. Strong sediment control measures will be critical to protecting the stream as well. The design will include a longer span bridge to avoid any impacts to the mussel.

  • Right-of-way segments will be required throughout the corridor.
  • Approximately 7.5 acres of wetlands, 4,500 linear feet of stream and 20 acres of forest are anticipated to be impacted. Off-site mitigation is planned.
  • Endangered dwarf wedge mussel is present in Norwich Creek. The new bridge will span Norwich Creek, with no work within the creek, to minimize impacts to the mussel.
  • The following utilities are present. Their relocations will occur prior to the roadway construction: Choptank Electric, Delmarva Power, Verizon, Comcast and Maryland Broadband Cooperative.
