The Martin Luther King Freeway is a five-mile-long (8.0 km) stretch of U.S. Route 58 (US 58) in the state of Virginia that connects State Route 164 (SR 164, Western Freeway) and the Midtown Tunnel complex with midtown Portsmouth at London Boulevard (which continues on and carries the US 58 designation to points west), continuing past High Street near US 17 and ending at Interstate 264 (I-264) in a full interchange that opened on March 28, 2017.

Efforts to extend the MLK Freeway have been in the works with VDOT as far back as the early 1990s, when the agency completed its initial environmental assessment.

After the lengthy review process required under the PPTA, then-Governor Bob McDonnell and VDOT executed the Comprehensive Agreement with ERC on December 5, 2011.

[3] Under the agreement, VDOT retains ownership and oversight of the tunnels and the MLK Freeway, while ERC finances, builds, operates and maintains the facilities for a 58-year concession period.

[2] However, Virginia Governor Terry McAuliffe announced on July 10, 2015, that $78 million of construction money originally designated for the now defunct Route 460 project (which was another PPP approved by his predecessor, Bob McDonnell) would be reallocated to buy out the MLK Freeway tolls for the remainder of the concession period.
