![Page 8: Widening of the Huey P. Long Bridge](https://reader034.vdocument.in/reader034/viewer/2022052602/55a226291a28ab92168b4788/html5/thumbnails/8.jpg)
Background – Huey P. Long Bridge
• Very heavily built
• Carries largest modern RR load without distress
• Many years of service life remaining

Project Background
• By widening the existing structure rather than constructing a new river crossing:
– Reduce environmental impact, property takings.
– Reduce project cost.
– Reuse existing right-of-way and traffic corridors.
• Final report published April 1988.
