First Girder Placement over Metro-North Tracks

Last night (October 23) the first girder assembly was pushed over the Hudson Line train tracks to the first set of piers; Metro-North adjusted its schedule to accommodate the maneuvers.

Additional schedule changes are planned for one Friday night each in November and December. Those dates haven’t been announced yet; alert for those who are heading into the city.

The beams are connected into a three-girder assembly on land, rolled on a track system designed for this purpose. They reach the land-based first pier and are pushed across the Hudson Line train tracks to the first in-river pier with added girders connected to the assembly and pushed west.

Smaller girder sections lifted from the Rockland trestle are bolted with cross beams that will support the concrete road deck, and each week two larger girders (average) are placed. The twin spans will have 31 miles of steel girders weighing in at more than 100,000 tons.

I’d like to know what you think.
