The plan is to remove all of the bridge parts dropped into the lake. They are starting work on that now. the new bridge is scheduled to open in 2011.
I have heard a rumor that no traffic will be allowed under the construction area. So, plan your trip for north of the bridge or south of the bridge but not running under the bridge. Also the boat launch that was under the bridge will be closed until construction is complete. I would be surprised if it is actually finished on time. I am sure we will hear more as we get closer to open water fishing.
