That's what I thought, just wanted to make sure I'd put it in the right category.

I wouldn't have added the bridge if it was modern, but there are very few concrete highway bridges this old that you can still drive across.

By definition, derelict simply means no longer maintained, and abandoned means no longer in service. So yes, I would still consider it to be correct.

Is derelict/abandoned the correct option here? Based on photos I believe you can still get across it by car, but the 1928 bridge means it's no longer in use.

Photos etc are available at the link I provided.
