I'm sure Zorrex or any civils around here can chime in .. but certainly it has something to do with bridge weight or design.MA roads suck ... I don't get why they repave the road surface but not the bridge road surfaces![]()
In NH, if there's a big pothole on the highway, instead of just filling it in, they will carve a huge square out of the road and repave completely. I'm very impressed.
