Metro’s Yellow Line, which runs through Crystal City and Pentagon City, could see major disruption next year due to needed repairs.
The proposed Yellow Line Bridge and tunnel rehabilitation project will include repairs to the bridge and the tunnels between the Pentagon and L’Enfant Plaza stations.
WMATA’s project website said the bridge is now showing “excessive wear and corrosion,” while “decades of water infiltration and underground moisture have eroded the steel-lined tunnels.” Both the bridge and the tunnels “date to original construction [of the Metro system] more than 40 years ago.”
The transit agency warned that long-term repairs are necessary to avoid structural failure.
The project will also upgrade the fire suppression system on the bridge, which is currently past its useful life according to WMATA. Further remediation work in the tunnel will repair cracks.
The exact timeline for the project is still unclear. Andrew Off, Vice President of Project Implementation and Construction, said a shutdown of the bridge is expected sometime in fall 2022.
“We expect to start sometime at the end of the next calendar year,” Off said. “We’re still working through with our general contractor on the specific construction duration for the Yellow Line Bridge closure.”
Meanwhile, further south on the Yellow Line, Off said a two-week closure is likely as WMATA connects the new Potomac Yard Metro station.
“We’ll have a scheduled two-week or 16-day shutdown in late summer or early fall in support of connecting the new Potomac Yard infill station to our existing system,” Off said.
The station had been scheduled to open next spring but was pushed back to September 2022 after an error was found in the project’s design. Alexandria leaders are still hopeful the project could be moved up to earlier in the year.
