Current Covid-19 Status:

As our state continues to experience effects of the COVID-19 outbreak, Grant County Public Works will be taking the necessary measures by following the recommendations from local, state, and federal officials in regards to social distancing.


All Grant County Public Works offices will be closed to public access effective Friday March 20, 2020 until further notice.





Employees will still be reporting to work and continuing their day-to-day job duties. We have installed a “Drive-Up Drop Box” located in front of our Public Works Administration building. This will allow the public to drop off permits, plans, and plats. 


To protect our community and staff we encourage communication by phone, email, and appointments.


*Effective immediately:  We will not be scheduling the Public Meeting room for use. Per Proclamation   20-14: Reduction of Statewide limits on Gatherings. If your agency or non-profit organization has the Public Meeting room scheduled, our office will be contacting you. We will revisit scheduling as new recommendations become available.  


Grant County Public Works thanks you for your understanding during these times.

The Public Works Department's primary responsibility is to maintain the County Road system by seal coating, asphalt overlays, snow removal, sign maintenance, bridge maintenance, road grading, etc. Public Works also performs small construction projects by County forces, and a variety of drainage projects throughout Grant County. Larger construction projects are open to the public for bid and contracted outside the department.


Public Works provides information on County roads and bridges, permits for access to County roads and culvert placement, oversize and overweight motor vehicle permits, work in the right-of-way and dust oil palliative permits. We also coordinate with other County departments on development review.
