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.

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.
