MIDTOWN TUNNEL PROJECT - Norfolk and Portsmouth, Va.
The Elizabeth River Tunnels Public-Private Partnership (P3) project is underway in the cities of Norfolk and Portsmouth, Virginia. MEC’s work includes construction and pre-construction services for electrical systems for the new Midtown Tunnel and Martin Luther King Expressway, and rehabilitation of the existing Downtown and Midtown Tunnels. Through 2018, MEC will be working with SKW Constructors, a Skanska, Kiewit, Weeks Marine Joint Venture.
The project contract was executed the first week of March 2013, and MEC’s work began in August with the rehabilitation of the Downtown Tunnel Westbound. Work consists of the replacement of the power systems, installation of a new fire alarm, security and air monitoring systems, and the start of an integrated Intelligent Transportation System (ITS), which will be connected throughout the entire project. A new conduit rack system is being installed, and will provide easy access for future owner maintenance. Existing tunnel lighting is being replaced with an efficient LED Tunnel Lighting System, and MEC is providing power and control feeds for new jet fans, which are equipped to withstand a 10MW fire event. Construction for the Downtown Tunnel Eastbound could begin as early as spring 2014.
In late 2014, construction of the new Midtown Tunnel will begin, with MEC providing all electrical systems for the new tunnel and the new support buildings. A new expressway will be constructed to create a direct freeway-to-freeway connection between the Midtown Tunnels and I-264, a major interstate that runs through the middle of the Norfolk and Portsmouth area. MEC will install and provide power to all the ITS devices that are to be placed in the new expressway, as well as the new fiber optic cable which will provide communication between all the Tunnels and the Martin Luther King Expressway.
