To be programmed |
There are also some historic circular intersections in rural areas.
One of those is in Dallas County at the intersection of 335th Street
and X Avenue, encircling a pioneer cemetery. Age is unknown and considerable
modification would be needed to meet current design standards for a
modern roundabout. Another has been identified in the town of Spillville
in Winneshiek County, age unknown but not of modern design.
