The steeply sloping reef was covered in a jumble of steel hawser, deck plates, twisted girder and hand-rail. |
The girder is in a position parallel to the ledger and supports the opposite end of the joists. |
Do a similar layout on the girder, so that you know exactly where each joist crosses the girder. |
Pier blocks serve as a transition from the posts supporting the girder to the concrete foundation footings. |
The arch's 4-ft-wide box girder is 6 ft deep at mid-span and 20 ft deep at the ends. |
On approaching the road overbridge, they noticed that the girder had collapsed and immediately stopped the train. |
