Interstate 464 (I-464) is an Interstate Highway in the U.S. state of Virginia. The highway runs 5.67 miles (9.12 km) from U.S. Route 17 (US 17) and Virginia State Route 168 (SR 168) in Chesapeake north to I-264 in Norfolk. I-464 connects two major highway junctions in the South Hampton Roads region. At its southern end, the Interstate meets two major highways that head toward North Carolina, US 17 and SR 168, and I-64, which follows the southern side of the Hampton Roads Beltway. At its northern terminus, I-464 has connections with Downtown Norfolk and Portsmouth via I-264.

Route description

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

Interstate 464 opened between Interstate 64 and U.S. 13 (Military Highway) in May 1967. The freeway was extended north from Military Highway to Virginia 337 (Poindexter Street) in July 1987.¹

The northernmost portion of Interstate 464 was opened to northbound traffic as part of the Berkley interchange project along Interstate 264 in Norfolk. Work along I-264 doubled capacity at the adjacent Downtown Tunnel to the west while expanding the new interchange with I-464. A ceremony preceded the reopening of the 1952 tunnel, which was previously renovated for a year, on December 20, 1988.²

Work along the Berkeley Bridge, the movable span linking Chesapeake with Downtown Norfolk via Interstate 264, continued through to May 24, 1990. Opening at that time was the second span for eastbound traffic, which serves departing traffic from Interstate 464 north. The $41-million project also focused on refurbishing the original 1952-bridge, which was switched to westbound traffic for I-264.³ The westbound Berkley Bridge closed for a year starting on October 19, 1990.³ It reopened on June 27, 1991.⁴

Tying into the south end of Interstate 464 is the Oak Grove Connector, a limited access link between the Hampton Roads Beltway and the Great Bridge Bypass. Designated as Virginia 168, the $38-million Oak Grove Connector was opened northbound in May 1999 and southbound after a ribbon cutting ceremony held on July 22, 1999. Planned since the 1960s, construction on the connector commenced in August 1997.⁵

Further south, the 10.2-mile tolled Chesapeake Expressway extends the high speed route of VA 168 to North Carolina. Costing $116-million and built by the Public Private Transportation Act, construction on the limited access road broke ground on July 12, 1999.⁶ The expressway opened following a ceremony held on the morning of May 23, 2001.^[3]

Under the Fixing America's Surface Transportation Act (FAST Act), the U.S. 17 corridor past the southern terminus is now designated part of the route of a Future Interstate 87 which will eventually continue the freeway south into North Carolina, then follow the route of U.S. Route 64 west to connect to Interstate 95 in Rocky Mount and eventually to Interstate 40 in Raleigh. This project will provide a critical southern freeway link between the Hampton Roads metropolitan area and North Carolina's Research Triangle.
