Where is interstate 39?

Interstate 39 is a long, east-west highway that runs through the state of Illinois from Normal, to the Wisconsin-Illinois state line near Stevens Point. The highway is known for its beautiful rural landscape and many fun things to do along the way, such as museums and skiing.

I-39 is not the longest interstate in the country, but it is certainly one of the most interesting. It starts out in very flat land, and gradually the landscape changes to more gently rolling hills and forests as it progresses north through Rockford, Illinois and the cities of Janesville and Madison, Wisconsin.

This is a great highway to travel through for a weekend trip. There are so many fun things to see and do along the route, from museums and skiing to botanical gardens.

Truck Accidents

If you’re traveling on the interstate, it is important to be aware of the dangers associated with fully-loaded commercial tractor-trailers. According to the National Highway Traffic Safety Administration, thousands of people are injured and killed each year in accidents involving trucks.

Earlier this week, a semi hauling flammable liquid was involved in a crash on I-39/90 near the Beltline exit that shut down the road for hours. The wreck was caused when the driver rolled over on his passenger side, spilling flammable liquid onto the roadway and causing a fuel leak.

All lanes have since reopened. The highway is still being repaired, but it looks as if the situation will be resolved soon.
