Hey all

Fairly new hear - Im 21 from Westen Australia

Im looking for some info on bridge building, the local MTB club i am with just took me on a track.

Now there are two areas that could do with some form of bridge - too much sand in these parts

How do i go about doing this?

How big of a gap are you trying to cross? If it is under or around 10ft. I would get 2 or 3 4"x4"s and anchor them with large steel spikes on each end, then just use some 2"x4"s as on top to give a good riding surface.

1) Welcome to da .

2) Root around on IMBA's web site.

3)) If you're new to riding, be cautious about "improving" existing trails until you learn which end is up. If the locals are riding it as it is, and the riding isn't damaging anything, leave it alone. More experienced riders like their challenges.

you used to be able to get the whistler building manual online, but the link is down.

use screws, not nails, use deck type construction, use pressure treated wood not scrap
