March Update on the Dulles Corridor Metrorail

The March issue of the Dulles Corridor Metrorail project newsletter (PDF) is online. Among the articles, look back at the first year of Dulles Rail construction, Route 7 changes and more.

According to the update, more than 95 percent of the construction of manholes and duct banks necessary for relocating the 21 utilities in the Route 7 alignment area have been completed. Some overhead power lines have been permanently removed and utility crews are now working in those manholes underground to connect the new lines.

In addition, 214 caissons, underground supports for the aerial structures, have been built and more than 207 concrete sections of the aerial guideway that will support the rail track have been built at a staging area at Dulles Airport.
