Sewer problems disrupted traffic on several streets in downtown Raleigh on Friday, and extensive repairs could make for a chaotic weekend.
A sewer main broke on West Martin Street, shutting down both lanes near South Dawson Street, and reducing lanes in the 300 block of South Dawson, near Nash Square.
The repair work on the road was expected to continue until 8 p.m. Saturday.
The closures on Saturday could worsen the traffic impact of concerts at Red Hat Amphitheater and events that will shut down both Fayetteville Street and Glenwood Avenue downtown.
A break in the line apparently formed after its last inspection. Dirt poured into the pipe, hollowing out a space beneath the street, which could have turned into a sinkhole.
The city noticed the problem because the sewer line had started to back up, according to T.J. Lynch, assistant director of public utilities.
