OK, this kind of turn is extremely easy to execute if you know a few basics.
The basic objective is to make the turn at the maximum radius the road allows. You do this by thinking outside, inside, outside, starting to the far side, swinging just past the inside corner, then back to the outside to finish.
Coming of the bridge, you want to establish momentum to the left because the traction is better on the bridge than the gravel, so slow to turning speed, at about 3mph walking speed until you prove you can do it faster. Start to the right side and start the turn to just clear the railing as you come off the span, then complete the turn on the dirt steering so make it as wide as possible, leaving about a foot margin for error. As you do this, keep in mind that you'll be leaning left so your head and shoulders will be closer to the rail than the wheels.
Also, until you have it completely dialed in, execute the turn coasting with the inside pedal down and that foot ready to dab if needed. That will give you the right pedal in power position to push through the turn and have you ready to continue.
One exception to this is if it's been raining. Wet wood is extremely slippery, so you'll need to slow way down much earlier, and not try to execute too much of the turn while on the bridge.
One nice thing is that the path also continues straight. So on a rainy day, if you find the wood deck to be treacherous, you can release brakes, and roll off the bridge straight, saving you from getting too personal with the steel side rails.
Coming the opposite way it's all the same, but you want to complete as much of the turn before hitting the bridge so you'll be vertical and ready to power up the slope.
