French contractor Freyssinet began lifting roof cables into place above the Welsh Rugby Union's 72,500 seater Millennium Stadium in Cardiff this week. The cables will support the WS Atkins designed 8,000t sliding steel roof from four 90m high masts. The roof was supported by four temporary steel towers during Wales' historic victory over South Africa at the stadium two weeks ago. Main contractor Laing now has eight weeks to increase the capacity from 27,163 to 50,000 for the next match against Canada on 21 August. Full opening is planned for the start of the Rugby World Cup in October.
