Watch the construction of a new Norfolk Southern Corp. bridge over Sixth Street in Springfield, Illinois, progress in the video below.
This drone footage was captured in December during the nine-day closure of Sixth Street as the contractor worked day and night to erect 1.4 million pounds of structural steel and install 18,600 bolts for the new bridge. Structural steel plate girders that are 13 feet, 2 inches deep were held in place by cranes during the installation. The round-the-clock work led to the roadway reopening to traffic one-and-a-half days early.
The work is part of the Springfield Rail Improvements Project, for which Hanson is providing services, including design and construction engineering. The structural steel for a new underpass at Fifth Street is being installed this month.
