Downtown Tunnel/Midtown Tunnel/MLK Extension

Location: Hampton Roads, Virginia Client: Virginia Department of Transportation

JMT is providing quality assurance for a $2.1 billion design-build tunnel and highway expansion project in Virginia.

As part of the Elizabeth River Crossings team with Skanska/Kiewit/Weeks Marine, JMT is providing quality assurance for the construction of the Downtown Tunnel/Midtown Tunnel/Martin Luther King Expressway extension project in Hampton Roads, Virginia. The $2.1 billion Design-Build Public Private Partnership project for the Virginia Department of Transportation (VDOT) will entail building a new Midtown Tunnel under the Elizabeth River, rehabilitation of the existing Midtown Tunnel as well as the Downtown Tunnel, and extension of the Martin Luther King Freeway from London Boulevard to I-264 with an interchange at High Street and other roadway modifications on local roadways.

The tunnel sections - each more than 300 feet in length and weighing 16,000 tons - are being precast at a Sparrows Point, Maryland berthing dock and will be transported by water approximately 200 miles to the project site in Hampton Roads. The first section of tunnel was moved to Virginia in June 2014.

JMT is leading the quality assurance and inspection/testing work for this complex project over the next several years.
