BALTIMORE (WJZ) — Crews continue to work to repair a broken water line below Ft. McHenry tunnel.

Maryland Transportation Authority crews will work on the broken lines during off-peak hours. They will also continue to monitor repairs made last week to an underground sump pump.

The issues were caused by cold temperatures.

“This week, MDTA crews will continue repairs to the broken water line beneath both the northbound and southbound Fort McHenry Tunnel bores,” said MDTA Executive Director Bruce W. Gartner. “As a proactive measure, crews also will be inspecting water lines beneath the Baltimore Harbor Tunnel. To minimize the impact to traffic, we’re coordinating this work with our regular overnight maintenance activities already scheduled in both tunnels.”

Traffic will be directed through the northbound and southbound tubes that remain opening.

Motorists should follow overhead and portable electronic signs.

Closures are as follows:

  • Monday through Thursday, March 2 – 5, from 7:30 p.m. to 4:30 a.m. the following morning – one southbound bore will close at 7:30 p.m., followed by one northbound bore at 9 p.m.
  • Friday and Saturday, March 6 – 7, from 9 p.m. to 8 a.m. the following morning
  • Sunday, March 8, from 7:30 p.m. to 4:30 a.m. the following morning.
