Township roads and bridges proving expensive

SIOUX FALLS, S.DL. (KELO AM) - There are over a hundred township bridges spread across Minnehaha County and many have low traffic counts. 

County Highway Superintendent D.J. Buthe says roads and bridges must be maintained.  But Buthe says some gravel roads away from Sioux Falls see only 5 to 10 cars a day.  He says there's more activity during harvest.

Buthe says improving or replacing bridges usually increases traffic counts

Commissioner Gerald Beninga questioned where funding for future projects will come from.  The commission says that depend on the state legislature.
