The new Tappan Zee Bridge now has its first horizontal piece. The 400-foot-long, 1,100-ton assemblage included three curved steel girders that was placed between two concrete piers. With the help of four crane operators, eight ironworkers and a GPS, the horizontal piece was finally put into place after three and a half hours of positioning it.

In all, 31 miles of girders will be placed to support a 3.1-mile road deck that is scheduled to be completed by the end of 2016.
