Thanks for the help.
Sorry, I segmented out the bridge this morning while straightening out the road. My thinking was that it would be easier to remove it completely if the bridge went away and private road it to avoid routing issues until it's status changes. Then I woke up and seeke'd guidance. It's not the only bridge to be closed recently in this area, so I want to know how to do it right.

As for the closure length: I can't find anything regarding a replacement plan... and doubt there is one due to County budget issues. I watched a presentation to the County Commissioners on bridge replacement, maintenance and inspection costs.. but nothing like a plan.
