Dane County sheriff’s deputies ramping up drinking and driving enforcement

A public hearing is scheduled to discuss proposed improvements to the Interstate 39/90 and Highway 43/81 interchange Wednesday.

The purpose of the proposed interchange improvements is to improve safety, meet current design standards, accommodate future traffic with acceptable level of service, replace aging pavement and structures, and enhance local mobility to the city of Beloit, officials said.

Officials hope the project will provide a safe and efficient transportation system between Illinois and Wisconsin to serve existing and future traffic demands while minimizing environmental disturbance, according to a release.


The project length totals 4.6 miles in the project area
The north-south leg of I-39/90 has a length of approximately 2.7 miles The east-west leg of WIS 81/Milwaukee Road and I-43 has a length of approximately 1.9 miles The alignment of I-39/90 will be shifted to the east such that the southbound lanes will be located on the existing location of the northbound lanes. It will also provide improved access to Gateway Business Park and maintains all other access to the Beloit urban area. The new I-39/90 and I-43/WIS 81 interchange will include posted 65 mph free flow movements from I-43 southbound to I-39/90 southbound and from I-39/90 northbound to I-43 northbound. It will also include posted 55 mph free flow movements from I-39/90 southbound to I-43 northbound and from I-43 southbound to I-39/90 northbound.

Officials anticipate that 82 acres of land will be needed to build the preferred alternative.
