This six block section of Central Avenue is located on the north side of the central business district. The largely linear district includes a jog at 18th Street. Below the jog the street was originally named Clay Street and above it Couler Avenue. It was also the dividing line where all commerce used the German language exclusively to the north. At one time the street featured a streetcar route and it was a significant farm-to-market route and a gateway into the city from the north. ()
