Construction Activity Alerts

Overnight Construction of Pedestrian Bridge

A noise variance has been issued to Potomac Yard Constructors for overnight construction to erect the pedestrian bridge over CSX rail tracks. This work is required to take place at night due to CSX regulations regarding work over the active roadway. Note, the work may not be continuous due to weather and availability of CSX work windows.

Start Date: March 29, 2021
End Date: April 26, 2021
Work Hours: 6 PM - 7 AM (Sunday - Saturday)

What Residents Can Expect: Crane, light tower, and boom lift noise throughout the night. PYC will insure the light towers and boom lifts are in place during daytime hours to minimize the noise and equipment alarms during nighttime hours. Without compromising a safe working environment, the light towers will be pointed away from residents’ homes as much as practicable.

For more information, please see Potomac Yard Metrorail Station Noise Variances.

Overnight Communications and Signal Upgrades

A noise variance has been issued to Potomac Yard Constructors for overnight construction to make communications and signal upgrades on the WMATA roadway. This includes installation of cable trough, conduits, and ballast. Equipment will consist of excavators, train engines and trailers, welders, generators, light plants, and hand tools.

Start Date: April 16, 2021
End Date: April 19, 2021
Work Hours: 6 PM - 7 AM

What Residents Can Expect:

  • Site Wide: Excavator, train, light tower, and dump truck noise throughout the night. PYC will do it’s best to ensure the light towers are in place during daytime hours, but this work will move along the WMATA tracks, so relocation of equipment will be required throughout the night. Without compromising a safe working environment, the light towers will be pointed away from residents’ homes as much as practicable.
  • 2601 Main Line Yard: Employee parking, use of office facilities, generators, movement of equipment, loading/unloading trucks

Pile Driving to Begin at South Pavilion

Potomac Yard Constructors (PYC) will be driving piles for the Potomac Yard Metrorail Station South Pavilion east the E. Glebe Rd. and Potomac Ave. intersection.

Start Date: March 15, 2021
Duration: Through May, weather permitting
Work Hours: 9 AM - 6 PM (Monday - Friday); 10 AM - 4 PM (Saturday)
