Officials with the Wisconsin Department of Transportation are asking July Fourth holiday travelers to buckle up, stay alert, and expect slower traffic in work zones and along major travel corridors. Peak travel times are expected between noon and 8 p.m. on Wednesday (July 3) and Sunday (July 7). Construction in most highway work zones will stop by noon on Wednesday (July 3) and will not resume until 6 a.m. on Monday, July 8.

While workers will open as many highway lanes as possible, motorists still need to be patient, alert and watch their speed. The Wisconsin State Patrol and local law enforcement agencies will be keeping an eye on traffic and assisting stranded motorists. Important safety tips for travelers:

  • Slow down. Excessive speed is a major factor in traffic crashes. Last year in Wisconsin, there were nearly 20,000 speed-related crashes resulting in 7,957 injuries and 173 fatalities.
  • Eliminate distractions and focus on the road ahead. Texting while driving is prohibited and very dangerous. Drivers in Wisconsin are also prohibited from using a handheld mobile device in work zones (except in an emergency).
  • Move Over or slow down when approaching emergency responders such as police and fire vehicles, ambulances, tow trucks and highway maintenance vehicles that are stopped along a highway with their warning lights flashing.
  • Properly secure trailers and cargo. If your vehicle breaks down, try to get safely off the highway. Remain buckled up inside your vehicle and wait for help to arrive.
