Work is underway as part of Phase 2 for the Central Waterfront Transmission Line Relocation Project (TLR). Crews are pulling and splicing from the existing vaults at Columbia Street to the existing vaults under the viaduct near South King Street. This work must be accomplished while the lines are de-energized. As part of this work, the pedestrian path at Columbia Street will be temporarily closed and pedestrians will be routed to the sidewalk along Colman Dock. Please follow all posted signs.

Night work at South King Street to relocate an existing duct bank and install a drainage manhole is scheduled to begin in November.

What to expect at Columbia Street:

  • Temporarily closure of pedestrian path at Columbia Street. Please follow the direction of signage to access your destination.
  • Work hours are from 7 a.m. to 5:30 p.m., Monday through Thursday.
