NS/SOU Bridge over Wabash River in Mt. Carmel, IL

(Bridge Hunter, Satellite)
20170107 7568c, downstream elevation
It is strange that the swing span is so close to the bank. If this was on the outer edge of a curve, it would make sense because that is where the channel would be deepest. But I checked the map, and the river is straight through here. Is it because the Patoka River dumping its water into the Wabash just upstream would create tricky currents that they wanted to stay away from?

Here is a sequence of shots I took on the upstream side starting with the flood wall for Mt. Carmel and then turning towards the east.

Then I moved closer to the bank of the Wabash to try to get a better upstream elevation shot. Black trusses against black trees just doesn't work very well.

[I contributed the above photo with the comment: "Black trusses work better against green trees and with a strong sun. But I don't have that much control of when I'm in that area."]

The picture you see below was in Ties Magazine (Southern Railway System). Bridge construction on the Wabash Near Mt. Carmel in 1872. Note the 4-4-0 wood burning locomotive.
On an interesting note. The original bid for the entire line in Indiana was 3.8 million dollars in 1869. Which is about 90 million with inflation today.
Augusts Bradley was president when the Air Line was formed.
Isaac Munroe St. John was the civil engineer who decided the best route for the Air Line.
St. John originally planned the line to be 245 miles from St. Louis to New Albany. It ended up being 268 miles to New Albany.
He was off 23 miles. New Albany subscribed $300,000 and Louisville subscribed $500,000 in 1869. Dubois county pledged $53,000.
Why did Louisville and New Albany want this new railroad to be built? Answer: it was the coal in Dubois, Pike and Gibson County that had been discovered and explored.
