Cattaraugus County’s road-closures page states County Road No. 5 (Mosher Hollow Road) will be closed from 2026-10-19 through 2026-10-30 for culvert work; a detour will be posted during the closure.

A county public notice and a FEMA notice describe the project as replacing or upgrading three existing culverts to address insufficient capacity and note the work occurs within a mapped 100-year floodplain and wetlands; the FEMA record identifies the selected alternative.

WHY IT MATTERSErieBizToday analysis

A culvert is a pipe or small bridge that channels water under a road. When culverts are too small for the flow they must carry, water can back up and flood the road or nearby land; replacing undersized culverts aims to reduce that flood risk by allowing water to pass more easily.

For drivers and local businesses, the main immediate effect is the planned road closure and posted detour from Oct. 19–30, 2026. Motorists who normally use County Road 5 (Mosher Hollow Road) will need to follow the posted detour route while crews work; the county’s road-closures notice is the source for detour and timing information.

Because the project lies inside a mapped 100-year floodplain and wetlands, federal review under FEMA has been part of the public record; the county’s public notice and FEMA documentation describe anticipated impacts and the chosen mitigation approach. That review explains why upgrades are being made and what environmental safeguards the county and FEMA considered.

What to watch next: the county’s road-closures and project public-notice pages for any schedule changes, detour maps, and a completion or reopening announcement after Oct. 30, 2026.
