These so called clip bonds were a completely different type of bridge. Instead of the steel lattic of a truss, they're hollow steel boxes reinforced with internal rib known as orthotropic decks. Supported from the piers bel by giant steel wings. If you look at each wing,

So, the engineers went for something much more radical.

00:00:05.072 --> 00:00:08.645

[narrator] The plan was to attach two new bridges

00:00:08.687 --> 00:00:11.765

to the old bridge, one on each side,

00:00:11.084 --> 00:00:16.245

doubling its capacity from four to eight lanes.

00:00:16.247 --> 00:00:20.845

These so called clip bonds were a completely different type of bridge.

00:00:20.847 --> 00:00:23.565

Instead of the steel lattic of a truss,

00:00:23.567 --> 00:00:27.965

they're hollow steel boxes reinforced with internal rib

00:00:27.967 --> 00:00:30.885

known as orthotropic decks.

00:00:30.887 --> 00:00:35.605

Supported from the piers bel by giant steel wings.

00:00:35.068 --> 00:00:38.001

If you look at each wing, you can actually see

00:00:38.127 --> 00:00:39.845

two vertical columns coming up.
