The I-5 overpass over WA-20 in Burlington, WA.

It started out being built in 1955 as twin 2-lane overpasses, then widened into one bridge in the mid-70's to accommodate on- and off-ramp lanes.

The long bridge over the potomac river in DC was built in 1903 with girders from the lower trenton bridge (now the trenton makes bridge) with a center swing truss span. In 1943 they removed the trenton bridge side spans and replaced them with new girders.

I found the original plans for the old US 71 Ouachita River bridge.

Here is the link to a PDF file with the plans for the bridge. It proves that the bridge was built as-is and wasn't pieced together at a later time. It's just an unusual and possibly unique bridge.

Interstate 75, Clay's Ferry bridge

"Built 1946 as part of US 25; twin span added 1963 as part of I-75; both spans widened in 1998 to form a single six-lane bridge"

I know this post is old, but I had no idea the bridge was cobbled together. The piers look pretty cool:

I had no idea US 71 even came close to the Ouachita River unless it was over a tiny tributary in a culvert.

Sadly the story is kind of not as cool as it looks on the surface. The only parts of the original spans in use in the 21st century are the piers.
