(NAPERVILLE) Roadwork on Illinois Route 59 will require a major traffic pattern shift in the west suburbs starting Wednesday and lasting through September.

The new traffic pattern will be installed on northbound Route 59 in Naperville and Aurora, reducing the road to a single lane between Jefferson Avenue/Liberty Street and North Aurora Road, according to a statement form the Illinois Department of Transportation.

Southbound lanes will remain unchanged, IDOT said.

The work is intended to increase the road’s capacity, reduce the potential for crashes and relieve traffic congestion, according to IDOT. Drivers are advised to allow extra travel time for the duration of the project, which should be finished by the end of September.
