    The Major Thoroughfare Plan is undergoing an update in 2017.  Find out how you can become involved in the process.

    What is the Major Thoroughfare Plan? 

    • The Jefferson County Major Thoroughfare Plan (MTP) identifies all existing and future roads and streets that are classified as collector or higher within Jefferson County.
    • The classification of a roadway dictates the standard templateAdobe Reader is required for viewing this document used, and design criteria, such as number of lanes, speed, and access, used for the construction of roadway improvements.
    • The MTP does not include local streets or roads.
    • The MTP is used to guide the County’s Capital Improvement Program and regulates development requirements to build public transportation infrastructure. 
    • The last update to the MTP was in 2012.
