A press release from the McHenry County Board:

Illinois Route 31 @ Virginia Road/Klasen Road Widening and Reconstruction Improvement; Completion of the final Stage III has occurred and the roadway is ready to be open to traffic.

[November 28, 2012 Algonquin, Lake in the Hills, Cary, IL] The McHenry County Division of Transportation is announcing that the roadway construction on Illinois Route 31 at Virginia Road/Klasen Road has been completed and that all lanes of traffic will be open on Thursday, November 29th.

Motorists should expect a slight delay the day of the opening as the traffic signals get turned on.

There is a small amount of remaining work to be done after the 29th which will be done using daily lane closures. The lane closures are expected to last until the middle of December.

Construction on Route 31 and Klasen Road on the Saturday of Algonquin’s Founders Days Parade.

Upon completion, the Illinois Route 31 @ Virginia Road/Klasen Road Widening and Reconstruction Improvements will tie into the Western Algonquin Bypass Project, connecting a key corridor for the area.

The project along IL 31 has seen many improvements take place because of the construction this year.

Those include over a mile of new reconstructed concrete pavement with four lanes of traffic and dual left turn lanes at Virginia Road.

The realignment of Virginia Road also was completed with efforts to increase safety at the intersection of IL 31.

The Klasen Road and Virginia Road intersections at Illinois Route 31 received modernized traffic signals.

A new bike path was paved along the entire length of the east side of IL 31.

Over two and a half miles of new storm sewer has been installed to go together with the open-ditch storm water system.

The final landscaping for Illinois Route 31 will be completed in the Spring of 2013. This work will take place under daily lane closures and may also include some small punch-list items.

The McHenry County Division of Transportation would like to thank you for your patience this past year while the project was being constructed.
