Our current office hours are Monday through Friday, 8:00 am to 4:30 pm. Our staff will sometime work in the field, or in other offices, we recommend calling to schedule in person visits. Road Crew hours are Monday through Thursday 6:00 am to 4:30 pm

New & Improved Encroachment Permit Application!
We’re excited to announce the launch of our new, simpler, and consolidated Encroachment Permit Application for Jefferson County Road Department projects.
Designed with convenience in mind, this streamlined application combines all the necessary steps and information into one simple form—saving you time and reducing paperwork.
Whether you’re applying for driveway access, utility work, or other activities within the county right-of-way, this new form makes it easier than ever to get started.
Failure to obtain a permit prior to any work within a county right-of-way may result in a one hundred dollar ($100.00) per day fine from the time of notice until the encroachment is either removed, or a permit has been approved, as well as any cost to the county for repairs or removal of the right-of-way. (MCA 7-14-2136,2137)
All new driveway installations or modifications require a new permit.
