In the mid-1960’s, master builder Robert Moses proposed construction of an additional $120 million tube for the tunnel, part of a master plan to revive the Mid-Manhattan Expressway and better handle traffic, reports NYCRoads.com.

The total cost of building the tunnel, had the additional tube been constructed, was projected to be $475 million. But due to the rising sentiments against new highways, the proposal was ultimately scrapped. Also, read about a few of Moses’ other proposals that were never built.
