Traffic Advisory - Hauling More TBM Parts
May 18, 2021
(Washington, DC) – DC Water’s contractor continues to disassemble and haul away parts of Chris the tunnel boring machine (TBM). Three pieces of the TBM will be removed and hauled this week to the project construction site near RFK Stadium. The upcoming removals will occur on or about May 19, May 20, and May 21, 2021, between 10 pm and 1 am.
The parts will be hauled on flatbed trucks and escorted by vehicles and flaggers to help navigate turns, if necessary. Short-duration road closures will occur along the haul route and temporary detour routes will be in effect until the truck passes.
Approximately 20 pieces in total will be transported via flatbed trucks from the drop shaft at 6th and R Streets, NW to the RFK site. Three pieces were removed and hauled on May 13 and 14. The next haul is scheduled to occur on or about May 24.
• R Street, NW will remain closed between 6th Street and Rhode Island Avenue.
• 6th Street, NW will be closed between Q Street and Rhode Island Avenue.
• Rhode Island Avenue, NW will be closed between 7th Street and 6th Street.
Please follow the detour signage associated with each road closure. Once the transport truck has been loaded, the contractor will reopen the travel lanes along Rhode Island Avenue and 6th Street, NW. R Street, NW will remain closed, except for the bike lane.
The truck route begins at the R Street construction site at Rhode Island Avenue, NW near 6th Street, heads south on Florida Avenue, NW to New York Avenue, NE. The trucks will merge onto I-295, exit on East Capitol Street, SE, and stop at the project construction site near parking lot 8 of RFK Stadium.
The Northeast Boundary Tunnel (NEBT) is the largest component of the Clean Rivers Project. It begins south of RFK Stadium and extends north to Rhode Island Avenue NE and west to 6th Street NW. The tunnel was excavated by “Chris” the tunnel boring machine (TBM). Its five-mile journey began in 2018 at the CSO 019 construction site located south of the RFK Stadium. It reached its destination in the Shaw neighborhood in April 2021. Once the NEBT is connected to the other Clean Rivers tunnels, combined sewer overflows to the Anacostia River will be reduced by 98 percent. In addition to controlling combined sewer overflows, the construction of the Northeast Boundary Tunnel will reduce the chance of flooding in the areas it serves from approximately 50 to 7 percent in any given year.
