From Portland go I-5 south. Exit 228 go west on Hi-way 34 as you near Corvallis OR. Follow sign to ocean beaches, you end up on Hi-way 20 west, heading west towards Newport Or. At the west entrance to Toledo Hi-way 229 is a right turn towards Siletz. Once in Siletz a right turn on Logsden Rd. will send you towards the Bridge it is a bit of a drive so be patient. Watch for a bridge on the right and you will know your there when you see the pillars from an old bridge next to the new one.(short cut) Before you reach Toledo watch for Sams creek Rd. on the right about 5 miles from the East entrance to Toledo. Its a dirt road and a bit windy, but it is fairly smooth. When it turns back into pavement your at the bridge. Another place to jump is just beyond Moonshine park. Stay on Logsden Rd. east from the bridge and turn left on moonshine Park Rd. go past Moonshine Park up the Dirt Rd a few miles. Stop where it looks like a rock quarry ( not the first one) a smaller one is after that. this link is from Tangent OR. After it says Hi-way 34 (which is exit 228 off of I-5. follow the rest. The bridge is 40 to 45 feet high. The channel under the bridge is 18 to 20 feet. In 20 years I have never hit the bottom.
