Try the map out!
A prototype of the map I have been working on (see previous post here) showing only data for Hennepin County is now available. I put this together quickly, so there is no functionality other than what is already built into Google Maps. You can click any of the highway lines for information on that historic corridor. I still need to nail down the data model, the visualization, and what pops up when you click on a line. I hope to add some customization to the view of the data (limiting by year in use, route, etc). This will all take time, but at least you can do a little exploring if you’re bored at work this week.
