Louisiana’s New Bridge cable stay installation complete

---

The bridge project, expected to be complete later this year, is part of the Louisiana TIMED Program and is being constructed by Audubon Bridge Constructors.

Installation of the last two cable stays of “the longest cable-stayed bridge in the Western Hemisphere”, the John James Audubon Bridge, was completed on 3 January, just five days after the spans were connected.

The John James Audubon Bridge, Louisiana’s newest crossing over the Mississippi River, now has all of its 136 cable stays in place.

Each cable stay is anchored to a 500-ft (152.4 m) tower, which provides support to the bridge deck. Each stay contains 20 to 69 individual cables for a total of 4548 cables. If the cables were placed end to end, they would stretch approximately 1200 miles (1931 km). Each stay is protected by an orange sheath, which has a spiral bead extending its length to resist rain and wind vibration.

The bridge project, expected to be complete later this year, is part of the Louisiana TIMED Program and is being constructed by Audubon Bridge Constructors (ABC), a joint venture of Flatiron Corporation, Granite Construction, and Parsons Transportation Group.

The TIMED Program is the single largest transportation program in Louisiana history. It is designed to enhance economic development in Louisiana through an investment in transportation projects and is funded by a dedicated $0.04 per gallon gasoline and motor fuels tax. ( KHL)
