Martin Luther King Jr. Expressway (Portsmouth)

The freeway effectively begins at the Pinners Point Interchange where the West Norfolk Bridge carries the Western Freeway across the Western Branch of the Elizabeth River, and where US 58 emerges from the Midtown Tunnel. It then continues south, connecting to London Boulevard in a full interchange, where it loses its US Route 58 designation as that route exits as part of London Boulevard. Continuing as SR 337, there is a partial interchange at High Street before the terminus with a full interchange at I-264/Alternate US Route 460.

As part of the long-term plan to improve the Midtown Tunnel connection, regional leaders and VDOT looked to extend the freeway from its terminus at High Street to I-264, creating a highway-speed alternate that connected not only I-264 to the Midtown Tunnel, but to the newly built Western Freeway as well. 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. The project again went through an environmental assessment in 1999, which was also the same time that VDOT began effectively pursuing the parallel Midtown Tunnel.

The extension became part of the Elizabeth River Tunnels Project when VDOT offered it as part of the public-private partnership solicitation in 2008. 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.[4]

The Martin Luther King Freeway portion of the project consists of extending the freeway from the end of the U.S. 58 concurrency terminus at London Boulevard to an interchange with I-264 with an interchange at High Street. Construction on the extension began in November 2014, with a completion date of March 28, 2017. In order to be built to freeway standards, it will eliminate all cross street traffic, including that at High Street, which will instead become a limited interchange. The other streets that were closed as a part of the project were either rerouted or turned into cul-de-sacs. The project also required the permanent closure of two I-264 ramps: I-264 East exit to Des Moines Ave, and I-264 entrance ramp from South Street.

After the extension is completed, the entire route will also then become the designated VA 164 Freeway. Although the freeway will run north and south nominally, the freeway will be signed as east and west, to continue the concurrency of VA 164.

The entire route is in Portsmouth.
