The second bridge rapid comes shortly after crossing under the second bridge.  Eddy out on the right to scout.  The rapid is fairly straightforward, but there a couple channels that look very consequential if you found yourself accidentally getting pushed the wrong way.  At lower flows, there is an easy portage by catching a small eddy on river left near the entrance of the rapid.  At higher flows, the only portage is up and around the rim, which, although I haven't tried it, follows a trail and likely isn't too bad of a carry.
