County transportation officials announced they will soon be activating flashing yellow turn signals at multiple intersections in the Crystal Lake and McHenry area.

The McHenry County Division of Transportation (MCDOT) said Friday they are activating flashing yellow arrow traffic signals at six intersections along both Walkup Road and Crystal Lake Road in Nunda Township.

The intersection of Crystal Lake Road and Bull Valley Road has already been activated.

The activation process for the other five intersections starts Monday and is expected to be completed by the end of May — weather permitting.

The five intersections on Crystal Lake Road and Walkup Road receiving traffic signal safety upgrades include Mason Hill Road, Crystal Springs Road, Edgewood Road, Pleasant Hill Road and Hillside Road.

MCDOT said that travelers approaching a flashing yellow arrow must first yield to oncoming vehicles, bicyclists and pedestrians before turning left with caution.

The intersections will temporarily turn into four-way stops while crews activate the new signal heads.

Travelers can expect delays during the signal upgrade process, MCDOT said.

Last year, work began to improve intersection safety along Crystal Lake Road and Walkup Road.

Work included crosswalk improvements at some locations, installation of flashing yellow arrow signals, various signal and safety improvements and traffic signal interconnect.
