POLITICIANS have pressed ministers to approve the delayed A303 Stonehenge tunnelling scheme.
The Highways Agency appointed a Balfour Beatty/ Costain joint venture to build a 2.1 km tunnel under the World Her itage site in 2002.
The scheme was put on hold by the Government last year pending a decision on whether to go ahead. Project costs rocketed from £300 million to £510 million due to unexpected ground conditions at the site.
Labour MP Gordon Marsden said in a parliamentary motion backed by 19 colleagues: 'This is the only option which fulfils the World Heritage site management plan and it is the only option deliverable by the Olympic year, 2012.'
