Team offers to build Dulles rail for $2.23B

A team of contractors is offering to build the first half of Rail to Dulles with a tunnel under Tysons Corner and a price tag about $400 million cheaper than the existing plan.

The defiant and likely doomed $2.23 billion proposal comes on the eve of major decisions for the transit project and represents the latest move in a complex, protracted battle to resurrect the Tysons tunnel idea.
