The issuance of STH connection permits is part of the broader subject of
access management. For access management related information, including its importance/benefits, land divisions, guidance on the basic principles, and Wisconsin statutes and administrative rules, click on the link above.
A driveway, public/private road, or recreational trail is a
connection between property that abuts STH right of way and the highway itself. On highways under WisDOT jurisdiction, a
STH connection permit is required when property owners and local agencies want to:
- Construct a new connection
- Remove an existing connection
- Relocate an existing connection
- Validate an existing unpermitted connection (when legal)
- Alter an existing connection, which includes a change of use
"Alter" means any change done to a connection beyond routine maintenance such as widening, paving, replacing a culvert, and improvements to the highway.
"Change of use" means any modification to a property that results in a change in the number and/or types of vehicles using a property’s connection. Property modifications may include, but are not limited to:
- Changing from a residential to a commercial or industrial use
- Changing from single to multiple residential use
- Subdividing to accommodate additional residences or businesses
- Changing the type of business
A connection is classified by its use or how it serves a property. Types of use include:
Commercial/industrial: A driveway or private road that serves a business or non-profit organization.
Residential: A driveway or private road that serves single and multiple family homes, apartments, condominiums, townhouses, etc.
Agricultural: A field entrance and entrances to recreational or hunting lands. This use may also serve to provide an entrance to farm buildings but not residential buildings. It does not include commercial-type activities.
Public road: A road, street, highway, etc. connecting to a state trunk highway that is maintained by a local unit of government. A road not maintained by a unit of government is categorized under commercial/industrial or residential.
Trail or trail crossing: Any pedestrian, bicycle, snowmobile, ATV or equestrian trail that runs longitudinally along and/or crosses a state trunk highway.
Some properties have access restrictions. Examples of restrictions include:
- No direct access is allowed to a state trunk highway
- Only one connection is allowed to a state trunk highway
- A connection has a specific use (for example, agricultural – not residential or commercial)
- A connection has to be built at a specific location
- A connection has right-in, right-out turns only (no median opening allowed)
A property or group of properties may also have multiple access restrictions, which should be specified in the property deed(s).
If a property has access restrictions, WisDOT may not be able to issue a STH connection permit or may only be able to issue a permit that meets the restrictions. WisDOT may also issue a STH connection permit with certain restrictions in order to ensure the safety and operability of a state trunk highway, for example, limiting the connection to a certain type of use or a maximum number of vehicles per day.
Applying for a STH connection permit
Fill out form
DT1504, Application/permit for connection to state trunk highway, and follow the instructions.
In addition to the application form, you will need to provide:
- A location sketch. You may use form
STH Connection location sketch
- Design details: dimensions, type/size of culverts, materials, surface grades, etc.
- A copy of the property deed
- Zoning documentation for the property, if a change in zoning will be forthcoming
- A copy of a certified survey map, if applicable
- Evidence of a land division, if applicable
- A work zone traffic control plan (TCP). Typically, any work that will encroach/block a travel lane or occupy a shoulder for more than 30 minutes will require a TCP. Consult the
Work Zone Field Manual or Traffic Control
Standard Detail Drawings for assistance.
You may also be asked to provide some type of proof that you have the authority to apply for a permit if you are not the property owner. A copy of an "Offer to Purchase Property" is an example of such proof.
► Submit the completed form plus the documents listed above to the
transportation region office responsible for the county where the connection is or will be located.
For faster permit application processing, submit all materials electronically via email, or for larger files, a file transfer protocol (FTP) site. If you do not have access to a FTP site, WisDOT can provide one. Submit the permit form as a Word document with an electronic (typed) signature instead of scanning it. Supporting materials should be in PDF format. You may also submit the application and supporting materials by regular mail. If you do this, the application must be filled out in ink.
Existing connections without permits
If an existing connection on your property does not have a valid WisDOT STH connection permit, you may be able to obtain a permit if it meets current law, standards and policy or if the connection can be legally altered or relocated to do so. Contact the transportation region office responsible for the county where the connection is located and a staff person will evaluate your situation.
Property owners and local agencies are expected to perform routine maintenance on the portion of their connections within state trunk highway right of way whether or not the connections have a valid WisDOT permit or are nonconforming. Routine maintenance includes items like removing snow, sealing asphalt, reshaping or grading gravel, culvert lining and cleanout, and minor repairs. Most of this work can usually be done without a permit. But a permit is required for work that affects traffic in some manner, disturbs the ground, or interferes with a WisDOT highway improvement or maintenance project. Replacing or regrading the connection or replacing a culvert, for example, or any activity that involves digging in the right of way, requires a permit.
WisDOT’s legal authority to issue STH connection permits comes from Wis. Stat. s. 86.07(2)(a) and Administrative Code
Trans 231. In Trans 231, you will find the allowable widths for a connection. This distance is measured at the right-of-way line – not at the edge of pavement. Under Trans 231, connections are allowed radii (flares) to accommodate turning movements. Radii can be as much as 10 feet for a residential connection and up to 40 feet for a commercial connection.
