Metro’s Yellow Line, which runs through Arlington and Alexandria, could see some closures next year as the Washington Metropolitan Area Transit Authority (WMATA) works to repair the Yellow Line Bridge between Virginia and D.C. and bring the Potomac Yard Metro station online.
Yellow Line Bridge and tunnel rehabilitation project will include repairs to the bridge and fix water-caused erosion in the tunnels.
The bridge was built in the 1970s and WMATA’s project website said it’s now showing “excessive wear and corrosion” while the tunnel has been subject to “decades of water infiltration and underground moisture [which] have eroded the steel-lined tunnels.” WMATA 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, and remediation work in the tunnel to repair cracks.
The exact timeline for the project is still unclear. Andrew Off, Vice President of Project Implementation and Construction, said a shutdown is expected sometime in fall 2022. The shutdown would close the bridge between the Pentagon and L’Enfant stations.
“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 to the network.
“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.
