ALGONQUIN – Construction on Route 31 at Virginia Road/Klasen Road is complete and all lanes of traffic will be open today, the McHenry County Division of Transportation said.
Motorists should expect a slight delay today as traffic signals are turned on, officials said.
A small amount of work remains and will be accomplished in daily lane closures that are expected to last until the middle of December, officials said.
The Route 31 improvements will tie into the eventual Western Algonquin Bypass Project.
Improvements along Route 31 this year include more than a mile of reconstructed concrete pavement, with four lanes of traffic and dual left-turn lanes at Virginia Road. Virginia Road also was realigned to increase safety.
The Klasen Road and Virginia Road intersections received modernized traffic signals, and a paved bike path was put in along the entire length of the east side of Route 31. More than 2.5 miles of new storm sewer also was installed.
Final landscaping for Route 31 will be completed in spring and involve daily lane closures.
