Map Notes

Historic information was taken from MnDOT construction logs, highway plans, right-of-way maps, official highway maps, historic aerial photos, and a few other sources.

Alignment lines were drawn using Google Earth. The map is powered by the Google Maps API.

All alignment lines are drawn to match up with the default aerial imagery used by Google Maps/Earth. Google updates the imagery from time to time - at which point I edit the alignment data if necessary (there may be a delay between when the imagery is updated and when the alignment data is updated).

I have tried to make the alignment lines as accurate as possible. This is done by overlaying old highway plans and aerial photos over the current imagery in Google Earth, and tracing the old roads on the plans. Any errors on the plans will therefore end up on the finished lines, so some of the alignments should be taken with a grain of salt, especially anything bypassed in the 1920's or 30's.
