There is an eddy on the right, directly under Trestle Bridge. If you go there, you can work your way under the bridge stress free, without worrying about mashing into the underside. The water is slow and manageable there. Once past the bridge you can work your way left to avoid the wall on the right.
I once saw a guy in the main current get sketched and bring his hands down. That brought the oars up into the bridge structure. It was not pretty!
