Last week, reported in the Burlington Hawk Eye.
With the completion of the Fort Madison bypass and rerouting onto interstates in the Quad Cities, the only two-lane stretches of US 61 in the state are the 32-mile segment between Burlington and the Muscatine/Louisa county line, and the three miles west of Keokuk. (Note that the Dubuque and Burlington pieces still are surface roads in some areas, though.)
