Commuters who travel north on Illinois 158 and then turn east on Illinois 13-15 will have to take an alternate route starting Monday.

According to the Illinois Department of Transportation, the eastbound ramp to Illinois 15 will be closed as part of the construction of a pair of roundabouts at the intersection of the two roads.

Drivers who need to head east on Illinois 13-15 can continue north to South Belt West and head east to Illinois 159 where they will be able to get on Illinois 13-15 to head toward Freeburg.
