In many cities, the interstate highways are being added and have been
added. The original guidelines no longer stand, and the fact is that
city bridges have been re-purposed to use for interstate traffic that
they were never intended nor designed to hold.

Shame on you. We know you're asking for a 'cite'.

I was trying to be original.

I don't know much about building bridges or "re-purposing" them, but
it seems to me that any existing highway or bridge that is taken over
by the state and made part of the federal interstate highway system
would have to meet current construction requirements and criteria
established by the Federal Highway Administration (under the
Department of Transportation).

I also suspect that the design criteria and requirements today are
superior to those used in the 1950s.
