Quincy Bayview Bridge

Posted April 16, 2008, by Ralph Mayse (ralphinator916 [at] juno [dot] com)

I find it interesting this bridge, barely over 20 years old, is rated as structurally deficient, yet the other bridge, nearly 80 years old, is rated as not deficient. I'm curious to know why this much younger bridge is deficient. Thank you, and I enjoy this website immensely.
