 | | Interstate 664 is the 20.7-mile-long freeway that connects I-64 in Hampton to I-64/I-264 in Chesapeake, completed in April 1992. |
 | | The tunnel is 4,800 feet long from portal to portal, and it was built by the immersed sunken tube method, comprised of 15 prefabricated segments each 300 feet long and with two 2-lane bores, placed by lay-barges and joined together in a trench dredged in the bottom of the harbor, and backfilled over with earth. |
 | | The final section of I-664 to open to traffic was the 6.2-mile-long section across Hampton Roads, which included the 4.6-mile Monitor-Merrimac Memorial Bridge-Tunnel, and it opened on April 30, 1992. |
