Bridges. They can be grand and majestic, awe-inspiring symbols of engineering ingenuity, city-defining pieces of infrastructure, and, as you may have heard by now, at serious risk of collapsing. To stop that from happening, engineers basically have two options: repair or replace. Both of those strategies are currently pursued in the New York City region.

As the New York Times explains in a new video, the Tappan Zee Bridge was in such bad shape that it made more sense to just build a new bridge right next to it at the cost $3.9 billion. When complete, the new structure will have express bus lanes, and a bike and pedestrian pathway. Now, obviously, the Brooklyn Bridge isn’t going anywhere, but the aging icon does need to have some work done. Instead of replacing the structure, the bridge has remained open while construction crews have been reconstructing its ramps and approaches, replacing 600 bridge bearings, and removing lead paint.
