A culvert replacement project in Butler County will require the closure of Iowa Highway 14 for up to three weeks.

Weather permitting, the Iowa Department of Transportation plans to barricade Iowa 14 south of Greene at 8 a.m. on Thursday (Sept. 28, 2017). The highway is supposed to reopen in early October, following completion of the project.

During the closure, signs will guide motorists onto an alternate route around the construction zone. The marked detour will follow Butler County roads C-23, T-24, and C-13. Permitted oversize loads will be prohibited on the detour route.
