Lane closures on eastbound Route 50 in Annapolis that began Tuesday night for repairs to a partially-collapsed drain pipe beneath the roadway will continue Thursday, according to the State Highway Administration.
Planned closures on Wednesday night have been delayed due to expected thunderstorms in the area.
The collapse caused a sinkhole to form in the roadway in June, but was only addressed with a temporary fix at the time.
The work ahead will include full closures of the eastbound highway near the exit for Aris T. Allen Boulevard, the SHA said.
Two lanes will now be closed between 8 p.m. and 10 p.m. Thursday and Saturday. All lanes will be closed from 10 p.m. to 5 a.m. Thursday to Friday and Saturday into Sunday.
During the full closures, drivers will be directed onto Aris T. Allen, then back onto Route 50.
The weather-dependent work was delayed to not include a closure on peak travel times on Friday — which is expected to be a busy travel day, the SHA said.
Following the temporary fix to fill the sinkhole last month, construction this week will return the metal pipe to working condition as a stormwater drain.
The work will include ground-penetrating radar to inspect for any voids near the collapse, sending video cameras into the pipe to look for other damage, lining the pipe and then repairing the road above it.
