Time-Lapse Video Shows Bridge Built in 2 Days

December 8, 2015

Using the sliding technique to replace side-by-side bridges, HNTB cut a projected two years of construction detours and delays into two nights, reports the Miami Herald.

The time-lapse video shows a new bridge being installed on an interstate in New York using a technique called "slide-in" in which a new bridge is built right next to an old one, and then slid in and hooked up, with a road closure of only a few hours rather than months.
