I'm also interested in knowing what n7xsd and blars are up to since we have all been trying to clean up the TIGER data around the Vegas area. From my trip over there in July, I've got over six thousand miles of gps tracks and I'm slowly making my way along my routes.

Started at Vegas and am currently on the I70 going across Utah towards Denver. Then it's up to the Black hills, back across to Yellowstone, down to Crater lake then down to Reno and back through Death Valley to Las Vegas again.

This is going to take all year.

The TIGER data for interstates is very messy. Usually only one track, not a bridge or overpass in sight and everything from roads, long gone dirt tracks, power lines, railways, all with connecting nodes on the interstate.

On the I-15 I had both directions with gps traces since someone had drives the southbound track but on the I70 I've only got the eastbound trace.

I'm using the Yahoo imagery to map the westbound lane but I hope that someone else will drive this (and capture a public gps track) and then improve my edits.

Hi,
If you realy want to see a messy TIGER interchange, have a look at the I15/I515 one in Las Vegas. A lot of bits or road are missing and half of what is there is going the wrong way.

I'm going to over there in a couple of weeks to see if I can sort it out. I figure that I'll need 12 seperate passes and then a couple of good photos from the top of the Stratosphere.
