Pipe replacement on Cary Parkway Expected to take about Three Weeks

RALEIGH - NCDOT engineers have determined the damage caused by a culvert fire under Cary Parkway Thursday night, March 21, between Two Creeks Road and Lake Pine Drive will require the replacement of 100 feet of pipe. That will keep at least the westbound side of the road at that location closed for about three weeks.

The fire caused extensive damage to a 12-by-8-foot culvert under the road (see attached picture). The cause of the fire is being investigated by the Cary Police Department.

Engineers considered inserting a "slip line", which is essentially a smaller pipe, into the culvert to provide support to the damaged sections, but they determined that was not a viable option. The damaged pipe must be removed, which will require tearing up the pavement, with the road then re-paved once the new pipe is in place. The estimated cost of the repair is at least $400,000.

Because this is considered an emergency repair, the usual bidding process is not required. A contractor should be hired by the end of next week. The replacement pipe must be custom made and that is expected to take about a week as well.

Cary officials were able to open the eastbound lanes to traffic in time for Friday morning rush hour traffic, and those lanes are expected to remain open for now. However, the westbound lanes will remain closed, and the entire road will have to be shut down once construction begins. Access to the residential communities along the road will remain open during construction.

Westbound traffic is currently being diverted to Tryon Road, then right onto Lake Pines Drive. Motorists are also encouraged to seek other alternate routes.

The section of Cary Parkway in this area carries as many as 30,000 vehicles a day.

NCDOT reminds motorists to watch signs for construction information, stay alert and obey the posted speed limit. Updated travel information is also available by calling 511 or online at In addition, NCDOT now offers travel information on Twitter.
