I live near this great bridge. Lots to say and I do love McCulloughs bridges all over the state. I have a few copies of pictures when he visited the site and of opening day. Dont know if anyone interested in me emailing these photos.

A great little bridge that's so cool to walk and gaze over at the dam and fish ladder with its low railing. A challenge to bike over with the narrow lane, but there's small enclaves along the side to let others pass.

I am so glad to see that they rehabilitated this bridge. It truly is beautiful and a treasure, albeit a bit scary to drive with the narrow lanes and the curve at the north end of the bridge.
