It runs east–west in suburban [Madison](/source/Madison%2C_Wisconsin) as a connector [freeway](/source/Freeway) between [Interstate 39](/source/Interstate_39), [Interstate 90](/source/Interstate_90), and [Interstate 94](/source/Interstate_94) at the Badger Interchange to [US 151](/source/U.S._Route_151) east of Downtown Madison. This section is all that remains of the highway that stood as of 1964 after [I-94](/source/Interstate_94) was commissioned.[1] This is the second alignment of the route number - the first beginning in [Platteville](/source/Platteville%2C_Wisconsin) and ending in [Readstown](/source/Readstown%2C_Wisconsin). ## Route description Western terminus (right) from US 151 WIS 30 is a freeway for its entire length and lies completely within the city of Madison. It junctions with [US 151](/source/U.S._Route_151) at a [folded diamond interchange](/source/Folded_diamond_interchange). West of the terminus, the road becomes Aberg Avenue which provides a shortcut to [WIS 113](/source/Wisconsin_Highway_113) north, providing a near-direct through route to [Dane County Regional Airport](/source/Dane_County_Regional_Airport) to the north via International Lane. WIS 30 has three interchanges between termini: one at Fair Oaks Avenue, one at Stoughton Road ([US 51](/source/U.S._Route_51_in_Wisconsin)) and a half-diamond at North Thompson Drive (CTH-T). The Thompson Drive interchange features [roundabouts](/source/Roundabout) at the ramp junctions with the crossing street. WIS 30 ends at its junction with Interstates [39](/source/Interstate_39), [90](/source/Interstate_90_in_Wisconsin) and [94](/source/Interstate_94_in_Wisconsin) at what is commonly known as the Badger Interchange. The roadway continues as Interstate 94 east, heading towards Milwaukee. The interchanges are numbered sequentially from west to east.[2] ## History From 1924 until the completion of [I-94](/source/Interstate_94_in_Wisconsin) between [Madison](/source/Madison%2C_Wisconsin) and [Milwaukee](/source/Milwaukee), WIS 30 ran from the [Wisconsin State Capitol](/source/Wisconsin_State_Capitol) from King Street east to Wisconsin Avenue in downtown [Milwaukee](/source/Milwaukee), along with [WIS 19](/source/Wisconsin_Highway_19). The route of WIS 30 had several different alignments during that time, all which generally parallel the current routing of I-94.[1] WIS 30 was the main route between the two largest cities in the state until I-94's completion in the late 1960s.[1] ## Exit list The entire highway is in [Madison](/source/Madison%2C_Wisconsin), [Dane County](/source/Dane_County%2C_Wisconsin). mi[3] km Exit Destinations Notes 0.00 0.00 1A US 151 (East Washington Avenue) Western terminus; road continues as Aberg Avenue 0.26 0.42 1B Fair Oaks Avenue 0.5 0.80 1C US 51 (Stoughton Road) 1.4 2.3 2 CTH-T (Thompson Drive) Eastbound exit and westbound entrance 2.1 3.4 3A I-39 south / I-90 east – Janesville, Chicago Left exit signed as exit 240A westbound, left entrance eastbound; I-90 west exits 138A-B 3B I-39 north / I-90 west / I-94 west – Wisconsin Dells Eastbound left exit and westbound entrance; I-90 east exit 138B 2.3 3.7 I-94 east – Milwaukee Eastern terminus; I-94 exit 240 1.000 mi = 1.609 km; 1.000 km = 0.621 mi Incomplete access ## See also - [U.S. Roads portal](https://en.wikipedia.org/wiki/Portal:U.S._Roads) ## References 1. ^ [***a***](#cite_ref-WIH_30_1-0) [***b***](#cite_ref-WIH_30_1-1) [***c***](#cite_ref-WIH_30_1-2) [***d***](#cite_ref-WIH_30_1-3) Bessert, Chris.
