Transportation officials said that crews have begun work on $12.9 million in road construction projects in McHenry County that will be finished by early fall.

The projects include intersection safety improvements and roadway paving, according to McHenry County Division of Transportation Public Information Officer Christopher Grask.

Crews will be installing flashing yellow arrow signals, crosswalk improvements, traffic signal interconnect and other various signal and safety improvements in Algonquin, Lake in the Hills and Huntley.

Those improvements will be made to seven intersections along Algonquin Road and at the intersection of Wilmot Road and Main Street in Spring Grove.

Road paving also begins this month for eastbound Algonquin Road from Cedar Ridge Drive to Meyer Drive, and Randall Road from County Line Road to Harnish Drive.

Work along westbound Algonquin Road from Ruth Road to Harvest Gate is expected to start in August.
