4. But the new station passage also needs to go under the northern side of the A10. How is that possible without opening up the A10?
In the place where the northern exit of the Brittenpassage will be, on Eduard van Beinumstraat, the old Atrium car park is underneath the A10. We intend to make use of that structure to create a northern exit for the Brittenpassage. This will prevent the need to close the A10 inner ring road for an eighth roof section.
5. Why not put the roof sections in place all in one go when the A10 has been dug up anyway?
Some of you were watching on the webcam and thinking ‘there must be a more efficient way of doing this’. If the A10 has been dug up anyway, you might as well put all of the roof sections into position at the same time. This would indeed save time and effort, but would not reduce the disruption. Because of the major disruption to traffic, we do not want to make a habit of closing the A10 and the railway on working days. Between 22.00 on Friday and 05.00 on Sunday, there are 52 workable hours in which everything needs to happen: dig up the A10, move railway tracks, cut piles to correct length, position supports, insert, replace the A10 and the track, resurface the road and deal with any setbacks that happen along the way. There is simply not enough time or space for three roof sections at the same time.
