In my career at a naval shipyard, equipment was taken apart, cleaned, examined, replaced or repaired if necessary, and either plated or primed-and-painted, before or after reassembly.
With the Johnson Street bridge being of riveted construction, this process could easily be used to restore the car and rail sections.
The rail span, now at Point Hope, should be examined as a basis for a repair to the current road bridge which could, still, be taken apart and restored as outlined.
These thoughts are based on a wish to see a wiser use of taxpayer money.
A bridge is not like a microwave oven or similar toss-and-replace items. Such wasteful thinking simply should not be allowed in this major project. This is a time to save, to fix, mend and brace.
We’d bet that the feds would applaud and support such innovation from a city that is willing to set an example by tightening its belt and having work done locally by its own citizens.
