State trunk highways (US- and state-numbered routes) in Wisconsin are
usually not physically "state-maintained" through the built-up
areas of many incorporated communities, rather being maintained by
the local municipality. These portions of the state highway system are referred
to by WisDOT as "Connecting
Highways." These connecting highways must be kept up to a specific
level of maintenance and standards defined by WisDOT.
Lists of these "Connecting
Highways" by WisDOT Region
can be found via the links at right or by clicking on the map below.
The specific Wisconsin Statutes which define Connecting Highways are
84.02(11) Connecting highways. The state trunk highway system shall
not include the marked routes thereof over the streets or highways
in municipalities which the department has designated as being connecting
highways. Those municipal streets or highways so excluded as state
trunk highways but marked as such and designated as connecting highways
are further described and the aids determined therefor under s. 86.32.
86.32(1) The department may designate, or rescind the designation
of, certain marked routes of the state trunk highway system over
the streets or highways in any municipality for which the municipality
will be responsible for maintenance and traffic control and the maintenance
and operation of any swing or lift bridge. Such maintenance, operation
and traffic control of the connecting highways and swing and lift
bridges shall be subject to review and approval by the department.
Those marked routes of the state trunk highway system designated
as connecting streets prior to July 1, 1977, shall become the connecting
highways in municipalities which are eligible for aids payments under
this section. The character of travel service provided by a route,
uniformity of maintenance, the effect on the maintaining agency,
and the municipality's maintenance capability will be considerations
by the secretary, in cooperation with the municipalities and counties
in making changes in the connecting highways of the state trunk highway
system in municipalities. The decision of the secretary to designate
or rescind a designation may be appealed to the division of hearings
and appeals, which may affirm, reverse or modify the secretary's
