Centennial Trail Culvert Repairs

Wade Road to Hilltop Road:

The Wade and Hilltop Road section of the Centennial Trail will reopen October 2, 2020 after summer construction to fix two sinkholes. We thank you for your patience as we completed this project and hope you can enjoy the trail this fall! 

 

The Centennial Trail between Wade Road and Hilltop Road had to close for several weeks during a portion of the construction in summer 2020 when 14 to 22-foot deep excavations (openings in the trail) were scheduled. These deep excavations were for the purpose of replacing a failed 12-inch culvert with a new 18-inch culvert and a 36-inch culvert with a required 9-foot diameter fish passable culvert. Additional culvert repairs during that time required partial closures (one lane and equestrian trail) with flaggers and signage. The project also included repaving the trail section and replanting along the trail.

 

Background:

In January 2017 a culvert conveying a small unnamed creek under the Centennial Trail collapsed causing a sinkhole extending from the trail surface down to the pipe. The hole was temporarily filled with gravel and the area secured with fencing closing one lane of the trail along with the equestrian trail section. Several other culverts between Wade Road and Hilltop Road were identified during design as failed (collapsed or condition meriting more than maintenance) or in need of repair and maintenance. The County anticipated construction in summer 2019 but design, permit delays and the fish window necessitate pushing the project out to 2020.
