I saw a blog post someplace from someone who got past the fence and crossed the bridge. He said that it was a scary experience because all the decking is rotted and he never knew when his next step was going to send him into the river. I'll have to see if I can find it again.
I think that the west end caught on fire two summers ago when wildfire swept through that area. Same fire burned a lot of the small bridges in the Army section of the trail. The bridges have been rebuilt apparently, I've not been through that section for a few years myself. Hope to change that next summer with an end-to-end ride.
In today's litigious environment, there is no way that bridge is opening without a full rehab.
It would be so cool to be able to ride across it...
