Hanover CC...owned by Dartmouth College.
Design had it origins with Ralph Barton and others....current course is a near-total redesign in 2002 by Ron Pritchard.
Holes 6 and 18 still cross though. 6 is a slight dogleg left par four of about 370, and 18 is a par 5 of 480. Both tees are separated from their respective fairways by the Vale of Tempe, a deep ravine that cuts the course in two. Those on the 18th tee have the right of way.
Brad,
This is a neat example, especially because when you stand on 6 tee it is visually difficult to realize that the holes cross. From Dan Wexler's book
Lost Links, there was originally a third nine (designed by Ralph Barton) that included a z-shaped par-five finisher through the ravine that currently divides the course.
As a side note, the course also includes back to back par threes, back to back short fours, a shared fairway between 8 and 9, and par fives in 3 of the last 4 holes (including 17 and 18). Hanover CC is quite the layout.
Recent lengthening of courses for major championships seems to create some crossover holes. I believe there was a cross in the course at Olympia Fields for the 2003 US Open. At this year's Walker Cup, 3 and 6 at Merion shared a back tee for the Saturday singles, which created a slight cross in the course.
