I-39/90 Expansion Project

Illinois state line to Madison, Dane and Rock counties

Speed limit reduction to 55 mph on Interstate 39/90, Beloit to Madison

Posted: June 1, 2018

A speed limit reduction to 55 mph will be implemented for the Interstate 39/90 work zone from just south of the US 12/18 (Beltline) Interchange near Madison to about three miles north of the Wisconsin-Illinois border. Two lanes of Interstate traffic are maintained in each direction during daytime hours and weekends. Motorists are advised to obey the posted speed limit. The new signs will be posted by early Saturday morning, June 2.

The Wisconsin State Patrol will be increasing efforts of surveillance along this corridor. This will include additional troopers patrolling the corridor and conducting aerial enforcements to enforce speed limits and other traffic laws.

Work zone safety is one of WisDOT’s top priorities and the penalties for careless driving are steep.

  • In work zones, penalties are doubled. Penalties for speeding may range up to $600. For motorists, a second violation within a year may carry a penalty of up to $1,200.
  • Careless drivers may face fines of up to $700 and a possible 3 ½ years in prison if they injure someone in a work zone. The fines for vehicular manslaughter are even higher, as are the prison terms – as many as 10 years. These punishments may increase if the driver was intoxicated or a repeat offender.
  • It is illegal to talk on a handheld mobile device while driving in a Wisconsin work zone. Drivers caught in violation face fines of up to $40 on first offense and $100 for subsequent offenses.

Remember, when you enter a work zone, be patient. Instead, slow down and pay attention to your surroundings.

  • Dont fool around. Eliminate distractions like eating, drinking, talking on the phone, or fiddling with electronic devices.
  • Expect the unexpected. Speed limits may be reduced, traffic lanes may be changed, and people and vehicles may be working on or near the road.
  • Slow down. A car traveling 60 mph travels 88 feet per second, and the faster you go the longer it takes to stop.
  • Give yourself room. Rear-end collisions are the most common work zone crashes, so don’t tailgate.
  • Allow about three seconds of braking distance. Look for signs. Orange, diamond-shaped signs usually give you ample warning of lane closings, construction areas, and flaggers and other workers ahead.
  • Be patient. If you don’t see workers, that doesn’t mean they’re not there. Observe the signs until you see one that says you’ve left the work zone.
  • Plan ahead. Leave early or map out an alternate route. Find the latest road conditions and work zone news at 511 Wisconsin.
  • Follow the law. Slow down and move over, if possible, when you see flashing lights.
