Clark Ave. reopened on Nov. 20 on schedule and ahead of the holiday weekend. Any final construction items for the project after this weekend will be completed outside of the right-of-way and will not impact traffic.
For this project, the contractor:
- Stabilized the construction area;
- Safely removed the aging stormwater pipe while installing the new pipes;
- Completed work on the water line that is in the project area; and,
- Repaired and repaved the road.
A sink hole formed on the downstream side of the sidewalk along Clark Avenue in mid-August 2018. It was determined that the sink hole was caused by cracks around the structure and deterioration of the stormwater pipe/culvert under the road. The condition of the pipe, which is 70 years old, continued to decline following a series of heavy rain storms.
The Stormwater Management Division, in coordination with the Transportation Department, took precautionary measures to close Clark Avenue on Sept. 11 leading up to Hurricane Florence given the unstable condition of this culvert and the potential risk to the area following initial forecasts of the storm.
The intent of the project is to replace the six-foot by nine-foot corrugated metal pipe that runs under Clark Avenue. This will significantly improve the stormwater system in this area.

|Late Fall 2018||Project construction complete|
The stormwater pipe under this portion of Clark Avenue is approximately 70 years old. Given the condition of the pipe and its continued deterioration, the pipe will be replaced sooner than expected to ensure the ongoing safety of Raleigh residents.
