DES MOINES (AP) — A small endangered bat could delay work on an Interstate 80 interchange that business and civic leaders hope will bring more businesses and jobs to Waukee and West Des Moines.

The lone female Indiana bat was found in late February just over a half mile from the $31 million proposed Interstate 80 interchange south of Waukee, the Des Moines Register reported Tuesday.

The bat is considered endangered by state and federal agencies. Now federal officials have asked for a study to determine whether the Indiana bat population would be harmed by the interchange construction.
