The 17th at Painswick plays - in the driving zone, no less - over a four way intersection, with the golfer unable to see if there is traffic coming from at least one of the roads!
Plus a cemetery on the left in the driving zone! It's a busy tee shot. There's also a set of stairs up to a viewing platform.
Dont forget that at Painswick one of those roads on the 17th is also driven across on 16. There is also the road that crosses where the 4th and 13th tees have their little face off.
A little known Alister MacKenzie course in Devon, Teignmouth has a road that crosses the 12th and 15th holes. Not usually a problem as its pretty wide open up there but it became obvious to me one day how dangerous it could be when I was driving through a thick fog and suddenly realised that I was on one of the roads crossing the golf course, but luckily there weren't many nutters out that day!
These are both pretty quiet country roads.
As already mentioned there are lots of examples of courses where the driveway, or a smaller access road to nearby houses or to the beach, pass over some holes like at St Enodoc, Ganton and Hunstanton.
There are also course which historically had holes crossing a road but had to be redesigned as the car became more popular. I'm thinking of Lindrick, site of the 1957 GB&I Ryder Cup Victory, when prior to the 1930s a couple of holes played across a road.
Lastly, and I'm sure there are tons of examples of this, but you have courses where you have to cross road between holes, where once it would have been not very busy and now one has to do their best chicken impersonation
Of specific interest on this front are Sutton Coldfield where the clubhouse has no view over the course as its on the other side of a busy suburban road. The other is Walton Heath, where the clubhouse and first hole are on one side of the road, while the rest of the old course and the whole of the new are on the other. I can't say for certain, but I'm sure at one point the roads in both these cases were not that busy, and the trees along them young, so there may have once been very little impact from the road?
Doug, as you are asking for examples, is it the safety aspect of cars and pedestrians crossing a golf hole or is it the incorporation of the tarmac surface that is the issue?
