The Wisconsin Department of Transportation (WisDOT) is requesting public feedback on proposed improvements at the US 18/151 and County F intersection near the Village of Blue Mounds in Dane County.

WisDOT is proposing to improve intersection safety and operations with a Restricted Crossing U-Turn, or RCUT. There are two RCUT designs under consideration – a J-Turn and a Median U-Turn.

  • The J-turn design allows County F traffic to turn right-in and right-out at the intersection. To turn left onto US 18/151, or continue across on County F, vehicles will turn right onto US 12/18 and use a U-Turn. US 18/151 traffic can make left turns onto County F.
  • The Median U-Turn does not allow US 18/151 traffic to make left turns onto County F. To turn left onto County F, drivers will continue through the U-Turn, then use the right turn lane on the opposite side of the road.

Both designs accomplish the desired safety improvements. The advantage of the J-turn is left turn lanes for US 18/151 traffic, while the Median U-Turn has a slightly smaller footprint and a lower cost. Construction at the intersection is currently scheduled for 2025.

Information regarding the US 18/151 and County F intersection project, including the proposed configuration, can be found at The public is encouraged to watch the narrated presentation explaining the project and submit feedback. Comments will be received through January 7, 2022.
