County Access / Driveway Permit (Public Works — Engineering) in Unincorporated Sweetwater County, Wyoming

New road access onto a county road, or any work/activity within a county road right-of-way not covered by a utility license, requires a County Access Permit from the Public Works Department's Engineering division. Utility lines crossing or paralleling a county road use a separate County Utility License (Type A for buried lines, Type B for overhead/short-parallel lines).

    Tips

    • Engineering (Public Works) regulates county-road utility crossings and vehicle access; this is separate from the Land Use zoning/construction permit and from utility Type A/B licenses.
    • The county's own page notes the County Address Permit application has moved to the Planning & Zoning (Land Use) Department's site, not Public Works.
