Located beneath the Bosporus in one of the world’s most seismically active areas, the first-ever roadway tunnel connecting Asia and Europe is set to open in late December—nearly a year ahead of the original schedule.
Under the design-build contract for the 5,700-ft-long Thimble Shoals tunnel parallel to the existing crossing in Virginia, construction would start in 2017.
Originally scheduled for completion late this year, the new 4,300-ft-long Midtown Tunnel between Norfolk and Portsmouth, Va., is now on track for completion by the end of the summer.
