Four Ways

Trailblazers for four US routes in downtown Dubuque, Iowa

With four US highways going through and around downtown Dubuque, Iowa, there are plenty of places where trailblazers are needed. The sign assembly at this intersection on Main Street in Dubuque is notable because of the use of FHWA Series D numbering, standard in most states, but not always in Iowa.
