What about the Other Tunnel?
The good people at tysonstunnel.org are making one last push for a tunnel for the Silver Line through Tysons Corner. They argue that the tunnel would be affordable and offer to perform some engineering studies to back-up their position.
They should also examine the costs for digging a second tunnel under the Potomac River to accommodate the added trains. The existing tunnel, which carries both Orange and Blue Lines, is essentially at capacity today. Even with the rerouting of some Blue Line trains across the Yellow Line bridge (which, of course, degrades Blue Line service for many Virginians who will need to cross over to D.C., rather than simply travel through Rosslyn), the tunnel will not likely be able to handle the added traffic. A second Potomac River crossing will soon be needed. What will it cost? Who will pay?
Don't expect any answers -- until it's too late.

And I suppose we should have the discussion as to wheter the crossing should be built under the river or above ground, too.
Is it that the Rosslyn station is buried too deep to make that possible?
