Sorry, when I wrote '57 degrees' I was being lazy: I meant 57 degrees 18 minutes and 5 seconds. The thread linked above on the Help site (this is the 'out-od-band' discussion) includes a link to a JPEG of the survey in question, so it makes more sense if you look at that. The S57°18′05″E 40.00' reference is not to this new road, but to a segment of the existing road that it connects to.

Hope that helps.
