The Belvidere Road Bridge, which carries traffic over I-90, is scheduled to close on Wednesday.
A detour will direct traffic to use Swanson Road and IL Route 251. Electronic message and constructions signs are in place to alert drivers of the closing. The construction is for bridge maintenance.
Up to 3,300 vehicles use the bridge daily.
Repair work is also scheduled to begin this week on ramps at the Rockton Road Interchange.
