Three giant trusses forming the northern section of the Emirates stadium’s new roof were lifted into position at the weekend.

Arsenal FC’s new Emirates stadium took a step nearer completion at the weekend when three massive roof trusses were craned into position.

The north section of the roof took three days to crane into place and consists of two northern halves of the primary roof truss and a secondary northern roof truss.

They were lifted by two Crawler cranes, which took ten hours to lift each of the three trusses into place.

The truss sections were brought to London from Watson Steel Structures yard in Bolton, and were assembled on-site, a process that took 13 weeks.

The 102m primary trusses weigh 370 tonnes each have a depth varying from 2m to 15m and a width stretching from 9m to 1.5m, The secondary section weighs 156 tonnes and is 9m deep and 6m wide.

The HOK-designed stadium in Ashburton Grove, North London is part of the regeneration of the Borough of Islington. Construction of the final south section of the stand by main contractor Sir Robert McAlpine will be completed in March 2005.
