Old vs new bridges

So, when bringing a freeway to interstate standards, this plan shows that the bridges that the main freeway bridge over will be replaced. They look fine to me... I don't see why they need to be replaced.

All of the southbound bridges were built in 1976, so they will be pushing 50 years old when they get around to doing construction.

The northbound bridges were built in 1999.  Less sure why they would want to replace those at the outset unless they don't meet interstate standard in some way.

Which is funny cause the US-264 bridges east of Wilson are older and it's already up to interstate standards and yet they didn't replace the bridges. I'm referring to the the Farmville bypass (US-258) and the VOA Site C rd bridges.

Seems like MSE walls are the new standard bridges for construction.

I didn't know they still build bridges like this.

I thought they stopped with this design...

I normally see double rails as the standard.

The Greenville Southwest Bypass (NC 11 bypass) bridges (which is kind of rare for freeways to have here in North Carolina except for older ones built back in the 60s and 70s) has the double railings over NC 903 and Abbott Farm Road.
