Temporary traffic wall

摘要

1-75 is a heavily travelled corridor in central Michigan. It carries heavy weekend tourist traffic to and from northern Michigan and Frankenmuth. In the spring of 2015, the Michigan Department of Transportation (MDOT) began reconstruction of a 3.8-mile section of the 1-75 corridor in Saginaw County. This $46 million project could easily have brought tourist traffic to a standstill and seriously affected Michigan's tourism industry. Using temporary concrete barrier to separate directional traffic would have restricted traffic to a 3/2 pattern through the duration of the project. Instead, MDOT chose to use the Road Zipper. This moveable barrier system kept three lanes open in the peak direction at all times, shifting the lane pattern under traffic in about 30 minutes while still providing positive barrier protection between opposing traffic lanes. The barrier provided three lanes north Wednesday through Saturday and three lanes south Sunday through Tuesday.
