CHEYENNE, Wyo. A problem with potholes has prompted officials to move toward banning heavy trucks from a road in far southeastern Wyoming, potentially hobbling a multi-million-dollar wind farm project launched by a Virginia company. The Laramie County Commission voted yesterday to ban certain vehicles from Laramie County Road 164. The ban could ultimately include heavy trucks, with exceptions for farm machinery and military trucks transporting ballistic missiles. Trucks had been using the road to haul gravel to the Cedar Creek Wind Project outside Grover, Colorado. When complete, the 480 (m) million dollar wind farm will have 274 turbines producing enough electricity for 120-thousand homes. The project was being developed by Greenlight Energy Incorporated of Charlottesville, Virginia. The company is linked to Houston-based B-P Alternative Energy North America.
