For the third year in a row, road construction is creating obstacles for travel to Carman-Ainsworth High School. This year, the busy Linden Road bridge over the Flint River between Beecher and Flushing roads is closed for rehabilitation. Traffic is being detoured via Flushing, Mill and Beecher roads. One plus is that the road closure does not affect C-A bus routes, school administrators said. The anticipated bridge project completion date is Oct. 10.
