Not easy to fall off accidentally, though, it has a good guard rail.
Thumbprinterr, I have to ask about Hwy 14, though. I've not ridden it and although I occasionally see bikes on it, it's quite narrow in many spots, often minimal shoulders, fast and moderately high traffic volume, and short sight lines. I gather your experience on it was OK? Any suggestions or advice about that part of the ride? Only one comment mentions it in http://www.rubbertotheroad.com/?p=57
and I have to wonder about write-up since it places the Chevron station on the wrong side of Bonneville Dam and doesn't mention the Skamania General Store at all.
the BoG is totally safe to ride over - i did it in a light rain and it was no problem at all. just follow normal precautions - keep a steady grip on the bars, look where you want to go, no sudden accelerations or braking. there is no way to fall off the side without getting off your bike and climbing over the rail, plus the 'roadway' is well separated from the guardrail. looking down while riding over the grating is very surreal, it becomes difficult to gauge the distance to the water in an interesting way.
as for the 14, it is true that there is very little shoulder on stretches of it, i have only done the ride leaving portland on a summer weekday morning and traffic was light to non-existent.
