State Trunk Highway 30 (often called Highway 30, STH-30 or WIS 30) is a state highway in the U.S. state of Wisconsin. It runs east–west in suburban Madison as a connector freeway between Interstate 39, Interstate 90, and Interstate 94 at the Badger Interchange to US 151 east of Downtown Madison. This section is all that remains of the highway that stood as of 1964 after I-94 was commissioned.^[1] This is the second alignment of the route number - the first beginning in Platteville and ending in Readstown.
