Lane Closings Continue Day and Night as Paving, Stations Finish Work, Mark Silver Line Progress

View From The Top: Significant progress is taking place at the Tysons Corner Station along the northwest side of Route 123 at Tysons Boulevard. Crews continue to work on installation of elevators, the pedestrian bridges and access pavilions. Escalators are under construction; these are some of the highest escalators in Phase 1, according to construction officials. The barrel canopy, the concrete topping on the slab and skylights are almost done. Pedestrians will be able to access Tysons Corner Center via a bridge across busy Route 123.

With completion of the construction of Phase 1 of the Dulles Corridor Metrorail Project expected in September, some major milestones have been reached but lots of work is still taking place. Construction is
92 percent complete.
Utility work is virtually complete. Aerial guideway is complete. Heavy station construction is complete and pedestrian bridges have been installed. Inside those stations and bridges, systems and finishing work is taking place.
While traffic impacts are easing all along the alignment, lane closings continue during the day and overnight.
Roads/Infrastructure
As work on final touches for Routes 7 and 123 and nearby roads continues, the framework for the sidewalks along Route 7 is clearly visible. Other work includes:
- Pavement restoration on I-66, the Dulles Connector Road, the Dulles Toll Road and the Dulles Airport Road where crews are also removing traffic barriers and installing permanent guardrails.
- Lane closings continue on Routes 7 and 123, Tysons Boulevard and other adjacent streets because of paving and other work related to significant shifts to complete the final reconfiguration.
- Significant closings, especially overnight, are happening on the Toll and Airport Roads near Wiehle Avenue.</li><li>Installation of electrical work for new traffic signals.
- Installation of permanent sidewalks, curb and entrances ongoing.</li><li>Installation of light pole foundations (Dominion Virginia Power will install light poles).
Drivers and pedestrians must remain aware of substantial nighttime milling and paving on Route 7 and Route 123. Specific details are available daily at
www.dullesmetro.com.
Testing- Test trains are running all along the alignment, with a focus on safe braking.
- Testing continues at all Traction Power Substations.
Stations
Stations are at various levels of completion with Wiehle-Reston East and the McLean Station (at Route 123 and Scotts Run/Colshire Drive) being closest to completion. Work continues on pedestrian bridges and entrance pavilions. Work includes:
- Installation of ceiling panels and curtain walls.
- Installation of elevators and escalators, primarily in pedestrian bridge pavilions.
The Dulles Corridor Metrorail Project is a 23-mile expansion of the existing Metrorail system. Known as the Silver Line, the extension is being built in two phases by the Metropolitan Washington Airports Authority (MWAA). Phase 1 construction completion is anticipated in September. The project then will be turned over to the Washington Metropolitan Washington Area Transit Authority (WMATA) for additional testing and scheduling of opening day.

Expansion At West Falls Church Rail Yard: The basement floor slab for the Service and Inspection Building has been placed and the steel framing is underway. In addition the wall and pier foundation for the Long Track Sound Cover Box, designed to minimize noise, is done.

Airports Authority Awards Contract for Phase 2 of the Silver Line
The Metropolitan Washington Airports Authority has awarded the contract for the major design-build portion of Phase 2 of the Silver Line to Capital Rail Constructors, a joint venture consisting of Clark Construction Group and Kiewit Infrastructure South Co.
The contract, which was officially awarded on May 14, formally names the team to design and build the 11.4-mile segment of the Silver Line, consisting of six stations and running from Reston, Va., through Washington Dulles International Airport and into Ashburn in eastern Loudoun County.
"This is the first of many milestones to come for the second phase of the Silver Line," said Jack Potter, President and CEO of MWAA. "The Phase 2 contract, awarded through a competitive bid process, and with the coordination and collaboration of our project partners, is moving forward to construction. Its completion will improve the transportation options for those traveling through the region and serve as a major driver for the local economy."
This contract is the largest of several Phase 2 procurement packages and represents approximately 50 percent of Phase 2 work. The stations are at Reston Town Center, Herndon, Innovation Center, Washington Dulles International Airport, Route 606 and Route 772/Ashburn.
The next step will be the issuance of a Notice to Proceed which is expected in July.

Evidence Of Sidewalks: Dulles Rail crews are continuing to build sidewalks and create spaces for plantings and street lights along Route 7. The light poles will later be installed by Dominion Virginia Power.
