Presentation given at 2010 Tulane Engineering Forum with Bruce Peterson. Presentation is a case study of the bridge widening design and construction.

1. Widening of the
Huey P. Long
Bridge
EXISTING
Tulane

Forum - 2010
PROPOSED WIDENING

2. Introduction
• Background
• 4 Construction Contracts
– Main Bridge – Substructure
– Main Bridge – Superstructure
Truss Widening
– Railroad Modifications
EXISTING
– Approaches and Main Bridge
Deck Widening
• Project Status
– Project Timeline
– Construction Photographs
PROPOSED WIDENING

3. Location
New Orleans Metro Area
French
Quarter
Huey P. Long Bridge

4. Before the Bridge

5. Construction of The Existing Bridge

6. Construction of The Existing Bridge

7. Background – Huey P. Long Bridge
• Combined
railroad –
highway
bridge
– 2 tracks
– 4 lanes – 9 ft.
width

8. Background – Huey P. Long Bridge
• Very heavily
built
• Carries largest
modern RR
load without
distress
• Many years of
service life
remaining

9. 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.

19. Cross Sections – Existing Bridge

20. Widened Main Bridge Features
• 2 new trusses added, parallel
to existing trusses.
• Roadways widened from 18
ft. to 43 ft.
• Currently: 2 – 9 ft. lanes
No offset
• Proposed: 3 – 11 ft.
lanes
8 ft. shoulder
2 ft. offset

21. Construction and Erection
• Sequence of
construction
– Widening Truss
• Imbalance
– Widened Floor
System

22. Maintenance of Traffic Through Construction
• Marine Traffic Maintained
– same vertical and horizontal
clearances
• Rail Traffic Maintained
• Vehicular Traffic Maintained
– by use of staged construction
