I-464 begins in the city of Chesapeake at the northern end of the directional interchange between US 17 (Dominion Boulevard) and SR 168 (Oak Grove Connector). US 17 heads south toward the Inner Banks community of Elizabeth City. SR 168 heads south toward the Outer Banks, including Nags Head and Manteo. Just north of I-464's terminus is a cloverleaf interchange with I-64 (Hampton Roads Beltway), between which US 17 and SR 168 run concurrently with northbound and southbound I-464, respectively. US 17 and SR 168 join I-64 for their own short concurrencies, with US 17 heading west toward Suffolk and SR 168 heading east toward Virginia Beach. I-464 heads north as a six-lane freeway that meets US 13 (Military Highway) at a diamond interchange and crosses over Norfolk Southern Railway's Norfolk District.[1][2]
I-464 passes over US 460 and SR 166 (Bainbridge Boulevard) with no access; the connection is made indirectly through a diamond interchange with Freeman Avenue, which serves one of the industrial areas along the Southern Branch Elizabeth River. The Interstate parallels Bainbridge Boulevard north to a cloverleaf interchange with SR 337 (Poindexter Street), which leads to the recently-replaced South Norfolk Jordan Bridge which provides alternate access to Portsmouth. I-464 crosses over another Norfolk Southern rail line at the boundary between Chesapeake and Norfolk and has a partial interchange with South Main Street before reaching its northern terminus at a directional interchange with I-264 in the Berkley neighborhood of Norfolk. The ramp from northbound I-464 to westbound I-264, which passes through a trench, also provides access to State Street and Berkley Avenue. Eastbound I-264 crosses the Eastern Branch Elizabeth River on the Berkley Bridge into Downtown Norfolk. Westbound I-264 passes under the Southern Branch via the Downtown Tunnel into the city of Portsmouth.[1][2]
History
Under the Fixing America's Surface Transportation Act (FAST Act), the US 17 corridor past the southern terminus is now designated part of the route of a Future I-87, which will eventually continue the freeway south into North Carolina, then follow the route of US 64 west to connect to I-95 in Rocky Mount and eventually to I-40 in Raleigh. This project will provide a critical southern freeway link between the Hampton Roads metropolitan area and North Carolina's Research Triangle.
