I was referring specifically to the road. The bridges in New York are marvels of engineering - and free as long as you’re walking or biking. The one that concerns me is the Manhattan Bridge and repeated torsion stress imposed by subways. Two trains on opposite sides of the bridge must cross at the same time to counterbalance the torsion, but the maximum stress when they first enter exacts a metal fatigue toll over time.
BTW, Happy 130th birthday today, Brooklyn Bridge!
