Hellgate Line Catenary Modifications
Bronx, N.Y. & Westchester, N.Y.
This project entailed rehabilitation of eight segments of catenary lines from New Rochelle to Sunnyside Yard. The existing systems, which were installed in the 1920s and 1930s, were due for rehabilitation because of age and as a preventative measure to help ensure that the catenary lines would hold in extreme weather events, such as a windstorm.

As the signature of Boston’s Big Dig project, the Leonard P. Zakim/Bunker Hill Bridge (Zakim Bridge), completed in 2002 and fully opened in 2004 is not only the world’s widest asymmetrical cable-stayed bridge, but it is also the first asymmetrical cable-stayed bridge in the nation.

Charlotte, N.C.
This bid-build project for the traction power electrification of Charlottte’s first light rail system included installation of 7 miles of at-grade and 3 miles of elevated track.
