One of the most critical parts of the project is the construction of a massive footbridge across the Moorgate railway line. The 105m long 20m wide structure at the south end of the stadium is one of two which will link it to local rail and underground stations.
It is now being fabricated on the south east corner of the site.
Another, smaller footbridge is being assembled at the north end of the stadium. This is 75m long and 14m wide.
The bigger footbridge will be assembled on a launch platform occupying the site of two of the shear cores. It will be jacked across the railway and off the shear core footprint during a possession in August. Its smaller sister is being assembled in two halves, which are due to be lifted into place over the East Coast Main Line during a possession this weekend.
Both footbridges are supported by huge, 6m deep, longitudinal steel trusses which give them the strength to clear the railway without forcing up the height of the deck. This is important as it will give emergency vehicles access to the new stadium.
The bridges are designed by consultant Buro Happold with fabricator Watson Steel providing the trusses. Contractor is Jackson Civil Engineering.
