Detour

I take Jacob to school down College Street. The city is doing road work on Lincoln Ave (a cross street), and so sometimes the road is closed and I have to find another route to get to Douglass Middle School. Last week I was going down College Street and there was a detour sign sending me to the left to go down Bush Street. I turned left and was shocked to see another detour sign on the next block sending me back the way I came! What the heck! Then today, I was sent right on Main Street and then I turned left down Elm...to another detour sign sending me back the way I came. Can't the crews communicate!
