Construction Notice: A culvert repair and replacement construction project is slated for the Centennial Trail between Wade Road and Hilltop Road during summer 2020. The project will require approximately 1-mile stretch of trail to be closed for several weeks.
Note: Wade Road is approximately 1/2-mile south of the Armar Trailhead and Hilltop Road is located 1 mile south of Wade Road.
The Centennial Trail between Wade Road and Hilltop Road will be closed for several weeks during a portion of the construction in summer 2020 when 14 to 22-foot deep excavations (openings in the trail) are scheduled. These deep excavations are 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 will require partial closures (one lane and equestrian trail) with flaggers and signage.
Additional updates will be posted nearer to construction.
In January 2017 a culvert conveying a small un-named creek under the Centennial Trail collapsed causing a sinkhole extending from the trail surface down to the pipe. The hole has been temporarily filled with gravel and the area secured with fencing closing one lane of the trail along with 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.
