The westbound Blanchette Memorial Bridge in MO on I-70 was built in 1957, torn down in 2012, and replaced with an almost identical replacement, maybe a bit wider? it has a different beam type, solid metal vs holy metal.
Sometimes, it's historic preservation at work, as with the earthquake-damaged Paihi Bridge on the county-owned part of Maui's Hana Highway. The replacement was built to the same appearance and specs, down to the deck width under 14 ft. (one-lane bridge carrying both directions of traffic).
The Tacoma Narrows Bridge that collapsed was replaced with a very similar one: 4-lane, long-span suspension. Just a bit more bracing.

Actually the replacement is similar in just two ways 1: it reuses the piers and a few of the approach piers 2: it is a suspension bridge.
Entirely different design in all respects.
The Delaware Memorial Bridge twin span, made to look like the original, built in 1968 almost ten years after.

That's a twinning, not an outright teardown and replacement.

U.S. 89A at marble canyon in AZ, almost identical, the old bridge was kept around so people could walk on it and take pictures. https://maps.google.com/maps?hl=en&ie=UTF8&ll=36.816504,-111.632359&spn=0.004033,0.008256&t=h&z=18&vpsrc=6&layer=c&cbll=36.816553,-111.632312&panoid=xxy_DvJtaguJFVGsD-cc4w&cbp=12,27.67,,0,-46.14 (https://maps.google.com/maps?hl=en&ie=UTF8&ll=36.816504,-111.632359&spn=0.004033,0.008256&t=h&z=18&vpsrc=6&layer=c&cbll=36.816553,-111.632312&panoid=xxy_DvJtaguJFVGsD-cc4w&cbp=12,27.67,,0,-46.14)
Here is another thought.
Has there ever been a washed out truss bridge, for example the delaware river flood of 1955 took out a few bridges, most were 50ish years old at the time, some even older still cross it, that had the missing spans perfectly replaced, versus a newer style of truss? For example a Pin connected Wrought iron truss being replaced with another Pin Connected wrought iron truss?
The Mullholland Drive bridge over I-405 in the Sepulveda Pass, the one that brought two "Carmageddon" closures, looks nearly identical to the original, just wider at the bottom.
Upstream span of I-29 crossing Big Sioux River was taken out by flood less than a year after opening. It was replaced with a nearly identical span except for deeper piers and piling.
