To preserve the surface of county roads, Public Works performs ongoing road surface preservation treatments. The county uses several different methods to preserve roads and to protect the public’s investment in its transportation infrastructure.

2025 Preservation Treatment Locations
Clark County provides an online interactive map so residents can get a general idea for where the 2025 Preservation Treatment locations are.
Public Works will notify neighborhoods affected by the 2025 Summer Road Preservation project prior to construction. Affected neighbors will receive a Public Works “Heads Up” notice in the mail.
In some cases, federal regulations require Clark County to build or upgrade sidewalk curb ramps so they are accessible to wheelchair users and other people with disabilities.
