ROCKFORD, Tenn. (AP) -- Rehabilitation of a bridge over the Little River near Rockford is more complicated than expected because of an endangered fish that likes to breed underneath.
Tennessee Department of Transportation spokesman Mark Nagi told The Associated Press that when the bridge needed work, an environmental consultant was brought in to make sure Duskytail Darters that live there are not harmed.
Darters are about 2 1/2 inches long and require clear water free of silt. Many have suffered from development practices that cause runoff into their waterways.
Darters are classified as endangered throughout their range in Tennessee and Virginia. They once lived in the middle Cumberland River and the upper Tennessee River as well.
Rehabilitation of the bridge on Old Knoxville Highway should be complete by Nov. 15.
