Washington Bridge was another bridge I was pretty sure I'd been to, but I couldn't prove it. (Eventually, I did dig up an Instagram post proving I was there three years ago.) And I knew for sure that the 145th St. Bridge was the final Manhattan-Bronx bridge I hadn't yet visited. So I headed uptown to see them both.
Washington Bridge is more interesting from below than from on it; it needs some TLC. You can get some nice views from it, particularly to the north.
145th St. Bridge is kind of cute.
