Idaho State Police say a semi-truck turning right from the Interstate 15 exit onto U.S. Highway 20 led to a concrete wall breaking free from the load, according to an ISP news release.

Troopers say that Allan Wiberg, 54, of Murray, UT was driving the 2004 Peterbilt pulling the large concrete wall on a flatbed truck.

When the wall fell from the trailer, it landed in the median of Highway 20, blocking lanes for about three hours. Crews were eventually able to remove the wall from the road.

ISP says the Idaho Transportation Department and the Idaho Falls Police Department helped out.


Idaho State Police reported around 3 p.m. the slab of concrete had been cleared from the road leaving just the construction lane closures in place.


IDAHO FALLS — Idaho State Police say to expect delays Thursday afternoon at the Interstate 15/U.S. Highway 20 interchange in Idaho Falls after a large slab of concrete fell off of a semi-truck.

Construction crews in the area are currently working on interchange improvements, which is already reducing lanes and creating congestion. The slab of concrete only further blocks traffic in the area.

It is not yet clear how long it will take crews to remove the debris from the road and ISP officials says it would be best for drivers to find an alternative route. will provide updates when they become available.
