I'm pretty sure that is the Hubbard Rd. bridge. Which, I believe, is currently impassable. But you can park in front of the blockade on the Hwy. 99 side.
Edit: on the other side of 99, at that bridge, is Dawson Road.
The only other lower river bridges (South of Monroe) are at Stow Pit Road (upstream / south) from Hubbard. And at Old River Rd. before it empties into the Willy.
@PKYi Maybe PK will chime in, and narrow it down.
P.S. You've got me wanting to look for bank access, this spring! My dad, and I, used to have private bank access just above the Hubbard Street bridge. Got lots of Crappie, just like the slabs in PK's vide, back in the day! I'll ask for permission first, before fishing any private land.
