# Hale Boggs Memorial Bridge – St. Charles Parish, Louisiana

**The Hale Boggs Memorial Bridge, which crosses the Mississippi River at Luling in St. Charles Parish, Louisiana, opened in 1983 as part of I-310 and was the first major cable-stayed bridge built in the United States.**

The main structure is 2,745 ft (837 m) long with a main span of 1,222 ft (372
m), providing a navigation channel of1,187 ft x 133 ft (362 m x 41 m). The
bridge deck is 82 ft (25 m) wide and carries four lanes of traffic with a full
shoulder on each side. During several inspections, corrosion was discovered in
the original stay cable system composed of parallel ¼” wires (up to 307 wires
per cable).

SYSTRA IBT developed a cable replacement strategy that minimizes impact on
traffic and modifications to the existing structure. The stays have been
replaced with a modern parallel strand system with superior durability and
maintenance characteristics. A system of temporary cables and saddles on top of
the pylons enables the bridge to remain in service throughout the stay
replacement procedure without the need for load restrictions.
