London Bridge Staircase - weekend installation of another flight...

2nd half-landing up to London Bridge

Another flight of our stair was craned into position over the side of London Bridge today. Fortunately, yesterday's high winds dropped to nothing, and in an exercise of extreme delicacy, the stair passed London Bridge with millimetres of clearance. As planned, the weight of the new component caused the new footbridge to deflect another few millimetres - on target, (by the time the final components are put in place), to precisely alter the pre-camber of the new footbridge, so that the top landing meets London Bridge at the correct level.
