RALEIGH, N.C. (WNCN) – A water main break closed Western Boulevard near I-440 on Wednesday.

Officials said Western Blvd. is still closed between Blue Ridge Road and Chaney Road for the repairs which were expected to be completed around 8 p.m. on Thursday.

However, traffic won’t be able to access the roadway until Wednesday Jan. 11, officials said.

They originally planned to reopen the road on Monday, however, they pushed the repaving and restriping work because of Sunday’s rain forecast.

The originally-extended road closure is not from problems with the busted pipe, Raleigh Water Public Information Officer Ed Buchan said. He told CBS 17 crews found three feet of asphalt plus concrete slabs under Western Boulevard.

“It’s very difficult to break through. You have to have heavy equipment on there with big hammers to bust through it so that’s just taken more time,” Buchan said.

The reason for the pipe break may be a combination of weather and old age.

“Wild swings in temperature that we sometimes get in North Carolina but also this is fairly old pipe. It’s probably from the 50s, maybe 60s era,” Buchan said.

While the repairs to the pipe are scheduled to be complete late Thursday. Crews then have to repave and stripe the road. That process will take longer than the repairs themselves.

“It’s a fairly major road. It’s a DOT road so they have certain specifications you have to meet. So, just a little more time consuming, but we’re gonna get it done,” said Buchan.

In the meantime, he asks drivers to follow the signs and stay out of the work zone.

“We’ve had some drivers go through those and that’s a danger to our crews so we want to make sure they’re safe,” Buchan said.

While Western Boulevard is closed, drivers will be detoured onto I-440 in both directions.

System Pressure Advisory

On Thursday, Raleigh Water issued a System Pressure Advisory for customers who lost water service because of the break.

The advisory is in effect until Friday morning, the department said.

The advisory is a public statement advising customers to boil tap water before consuming it, Raleigh Water’s website states.

Advisories are issued when an event has occurred allowing the possibility for the water distribution system to become contaminated. 

An advisory does not mean that the water is contaminated, but rather that it could be contaminated; because the water quality is unknown, customers should assume the water is unsafe to drink and take the appropriate precautions, the site stated.

This differs from a boil water notice which is issued when contamination is confirmed in the water system. During a notice, all customers must boil their water before consuming it or use bottled water, the department stated.
