Shortly after Governor Kaine's decision, the Greater McLean Chamber of Commerce formed a coalition of tunnel supporters, called Tysons Tunnel, Inc. and put forth a technical proposal to help revive consideration of building a tunnel through Tysons. The Virginia Department of Rail and Public Transportation hired an independent consultant to assess the coalition's proposal. However, the consultant's report – sent to Secretary Homer on March 7, 2007 stated that "here is a significant risk that the project cost of a Large Bore Tunnel would not meet the Federal Transit Administration's cost-effectiveness ratio criteria, which could compromise federal funding for the project".
