Area 3 - Difficult Run and Colvin Run

 Area 3, from Colvin Forest Drive to Faulkner Drive, includes the Difficult Run bridge, Colvin Run stream relocation, and a box culvert under Carpers Farm Way.

Area 3

Utility relocations will be ongoing throughout the corridor through mid-2023. Additional upcoming work includes:

Early 2021: The box culvert under Carpers Farm Way is scheduled to be completed. Colvin Run will be diverted to the new permanent stream channel between Carpers Farm Way and the Difficult Run bridge. Small weirs placed in a staggered pattern along the stream bed will encourage a meandering flow pattern and the growth of vegetation within the stream channel. Construction of the south half of the pedestrian underpass under Route 7 is scheduled to start. Crews will begin partial demolition of the existing bridge over Difficult Run.

Spring 2021: Construction of the retaining wall along Colvin Run and the eastbound Route 7 bridge over Difficult Run will start, with completion expected later in 2021.

Winter 2021/2022: Crews are expected to complete the eastbound side of the Difficult Run bridge, and all eastbound and westbound traffic Route 7 traffic will be placed on the new eastbound bridge while construction of the new westbound bridge is ongoing.

2022:  Construction of the new westbound bridge over Difficult Run will take place throughout 2022.
