SANDY SPRINGS, Ga. -- The Chattahoochee River National Recreation Area is getting some unusual help with a bridge project near Bowman's Island.
Several pack mules have been enlisted to haul in materials for pre-engineered trail bridges.

Florida-based Hydra Engineering, which is heading up the project, determined that mules would be best for bringing heavy gear into remote areas of the park.
"Some advantages of 'mule power' include minimal impact to trails, limited use of gasoline or other non-renewable fuels and minimal disturbance of the natural quiet in these remote areas," Chattahoochee Chief of Resource Education Nancy Walther said in a statement.
In preparation for the project, the mules were put on a special diet to make sure they wouldn't introduce non-native plants to the area.
Their work is scheduled to wrap up on Friday.
