Illinois state line to Madison, Dane and Rock counties

I-39/90 traffic: be alert for crossovers in work zones

Crossovers are located in various locations along Interstate 39/90 between Beloit and Madison. Motorists heading north (or south) on the Interstate will encounter crossovers, directing them to shift onto the southbound (or northbound) side of I-39/90 as crews reconstruct the opposite side of the Interstate. Two lanes remain open to traffic on I-39/90 (in each direction) during daytime hours.

Watch the below video to learn more about traffic crossovers along the Interstate in Dane and Rock counties.


For everyone’s safety, please:

  • Pay attention. Keep your head up and phone down when driving. Avoid distractions when behind the wheel.
  • Give yourself room. Rear-end collisions are one of the most common work zone crashes, so do not tailgate!
  • Plan ahead. Leave early or map out an alternate route. Find the latest road conditions and work zone news at www.511wi.gov.
