Not very long ago ---- unless time goes by faster than I realize --- there was a topic here featuring a superb model of the Mianus draw.  And, somewhree in that topic I think I asked what is the length of the bridge.  And,  I got an answer.  Now I can't find that topic for nuthin'     Help?

This drawing of the span may be of interest:

The original 19th century Mianus River Bridge at Cos Cob had a swing center span, similar to the Norwalk River Bridge, which was then replaced with a single two-track rolling bascule lift in 1904.  A second two-track span with lift section was added by 1906 as it presently exists.
