The roadways at the diverging-diamond interchange in Sartell should be totally open Oct. 21, according to Sartell City Engineer Mike Nielson.
In recent months, that area (Hwy. 15 and CR 120) has been a maze of detours because of construction of the complex $9-million project, the first of its kind in Minnesota.
The concept of the diverging diamond is that left-turning vehicles will never meet head-on with vehicles coming from the opposite direction. Hwy. 15 had to be lowered nearly 20 feet for the project, which is just west of the Epic Center development.
