CHARLESTON, W.Va. -- West Virginia officials on Thursday urged motorists to use caution in work zones because two Division of Highways workers recently have been hit by vehicles.

Department of Transportation spokeswoman Carrie Bly said both workers were struck while clearing roadside debris resulting from superstorm Sandy.

One worker is in critical condition after being hit Wednesday in Nicholas County. The other worker suffered minor injuries when he was hit Saturday in Randolph.

Bly said all roads that were closed because of Sandy have been reopened. Now, DOH crews are collecting debris left along roadsides.

Transportation Secretary Paul Mattox said motorists should slow down and stay alert in work zones.
