The second of two old railroad bridges dropped in the river below the existing railroad bridge is at river mile 84.5.  In low water this is a hazard and paddlers should proceed with caution.  If you see parts (pipe, iron, struts, etc.) sticking up through the water, avoid them.  Do not float close to them as they are attached to the old bridge and parts of it may be just below the water.  It would be very dangerous to entangle your boat or yourself in this structure.  Even if you see no obstructions, they may be just below the water.  Floating under this bridge on the right (south) bank is the best option.In this picture you can see posts sticking out of the water under the bridge.

 

Note the parts of the old bridge exposed above the water in the photo below taken from the south bank.
