Does anyone know how the full width of the carriageway gets surfaced in this setup? Perhaps lane closures on the left/right side (sequentially) after the centre portion has been resurfaced?
The bridge itself is wide enough to resurface one lane. But its wheels can move in any direction. So instead of driving forward to do the next section you can also drive three meters to the left or right to do another lane instead.
In general the entire bridge is as maneuverable as a 230m structure can be. The individual segments are designed to articulate. So once it's set up you can move it around to any other patch of road surface in the area.
