can someone point me to a source that gives exact city block dimensions of the Chicago Loop?

Question

I'm modeling the loop on a computer and need specific measurement information

Answer 1

Look here:

Answer 2

I researched alittle, played a little... Each block is .8 (eight-tenths) of a mile corner to corner.

What I did: Using Google Earth (http://earth.google.com/download-earth.html), I zoomed in tight on downtown Chicago and used Tools > Measure. Since the Chicago images are from low-flying planes, you could also save several images to your computer, or print. The measure tool is very accurate, and the Chicago GE very detailed, so you should be able to not only get the measurements, but also the detail you need, especially if you zoom in tight. Play with the checkboxes for Roads or Buildings, as well as the navigation tools, and you'll be up all night (pan down and try to "fly" between the buildings)! Also, under Layers on GE, theres a section for Transportation, then under that there are boxes for local and commuter railroads, and stations that will help too.

If strange things show up on the GE layout, look to see if any checkboxes are filled that you don't need at the bottom and at the left.

Search Chicago on the GE window, or copy and paste this for the intersection of State and Madison: 41 52 55.38n 87 37 40.11w

For what you're doing, Google Earth is a GREAT tool!
