Here are two good videos of the building of the 675: https://www.youtube.com/watch?v=SnTA52Hy6xM&feature=related https://www.youtube.com/watch?v=o5E7fBrzA7A&feature=related Can anyone tell me what interstate in Northern California is being referred two at 1:59 in the first video?
Not sure about the interstate, but did work for the Engineering lab in Benton Harbor, Mi. on the 675 project and along with Simmons machinery out of Birmingham, Al. set one up at Drummond Coal in Jasper, Al.
These are great historical videos, I've watched them too many times and I've got them in a playlist haha. The 70's music is classic.
