At Bloomsburg Pa, make a left off route 11 onto N Iron St. That turns into Millville Road. Take it till you pass Interstate 80, make your next right onto School House Rd. that comes to a Y intersection you want to stay straight with the river to your right. about 1/4 a mile from there you’ll see a pull over shoulder to your right. park there, you should be able to see the bridge from there. The trestle is roughly 25 ft. you jump off the end of it towards what looks like an old submerged box car. the whole area is great for swimming, camping, fishing or pulling off some flips. frequently visited as well.
