1899+1939 US-12 Bridges over Snake River between Lewiston, ID, and Clarkston, WA

1899: (Archived Bridge Hunter, the description has a history)
1939: (no Bridge Hunter; no Historic Bridges; Satellite)

The first "Lewiston" was destroyed by fire along with the "Spokane" in 1922.

When I saw this levee, I thought Lewiston had some serious flooding issues. But when I saw the portal view from Clarkston at the top of these notes, I realized that the river is always higher than Lewiston. So the pool of the Lower Granite Dam would have inundated the town if they had not built the levee.

This view confirms that the river is always higher than the town.

The first vertical lift drawbridge in the inland Pacific Northwest, this drawbridge only lifted a few times before the riverboats operating in this section were made obsolete by dams and locks further upstream. A bridge first spanned this section of the Snake river in 1899, linking the two cities between WA and ID named after some of America's most intrepid explorers. A great shot of color against a mono-chrome brown landscape! More coming soon to the main site...stay tuned!

Lewiston is the origin for much of the grain export barge traffic on the Snake River. That traffic is the main argument for not removing the four locks and dams on the Snake River. But I see the grain terminals are along the Clearwater River rather than upstream of this bridge. I've read that Lewiston is a significant inland port in terms of tonnage. It looks like they handle logs, wind turbine parts and containers as well as grain.
