The trestle is in a south backwater shallow 10-15 acre section of the lake that you can't even get your boat into. It's maybe 2-300 ft tall and several 100 yds long and hadn't been maintained for over 20 yrs. They have been reworking theentire rebuilding of the tracks for about a year as it's well used. So I am guessing they are going to work on the support structure and for how long the article didn't say. I would imagine the lake might be down for quite a while the way they have totally rebuilt the tracks and all the crossings.
