Are they able to raise clearances much? I mean you'd have to redo long approaches. I guess they could use some really wide flange stringers to give a few extra inches of clearance or maybe cut down on some of that built up track bed.
Usually it's easier to pay the city to drop the road level...sewers and all...especially when there's an existing drainage problem and a major solution is needed.
Strike beams are usually installed when there's absolutely no other alternative...but they've done such an overhaul here, this is really quite surprising.
14'6" is non-restricted clearance. Can't quite tell if the bridge is even close to that. Looks like ~12'6"
