Two super-sized steel girders are on the way to the new Tappan Zee Bridge.
They each weigh around 80 tons. The biggest one is 130-feet long, which is almost half the length of a football field.
The girders are headed by truck from Pennsylvania to Albany, and will then will be floated down the Hudson River on barges to the construction site.
Traffic could start rolling on part of the bridge later this year.
