Effective Monday, June 22, 230th street, approximately two miles southeast of Panora will be closed at the junction of the Raccoon River Valley Trail. Guthrie County Conservation Director Joe Hanner says construction will take place on a paved secondary road crossing and will take about a week to complete. Cyclists using the trail will be able to walk their bikes around the construction area to use the trail. For more information, call Guthrie County Conservation at 641-755-3061.
