Project Description

Client: The Port of New Orleans

Location: New Orleans, LA

Date of Completion: Dec 2014

When a routine inspection of the Seabrook Railroad Bridge in eastern New Orleans revealed that deterioration of metalwork on the bascule span’s long abandoned vehicular roadway might have posed a public hazard, Boh Bros. was awarded an emergency contract to make the repairs. The bridge spans the Inner Harbor Navigation Canal where it meets the southern edge of Lake Pontchartrain. The job called for the removal of about 100 tons of old roadway components and the addition of 22 different members—steel ballast beams and plates of varying sizes and shapes—totaling 100 tons. Boh had to eye the bridge, measure out the rivet patterns and fabricate custom brackets for each location it had to match, each one slightly different.

Challenges: The balance of the bridge had to be maintained throughout construction prior to the waterway closure. The team had to weigh each piece that was removed and make sure they didn’t add more weight than was originally on the structure. An equal condition had to be maintained from beginning to end.

Project Description

Client: New Orleans Public Belt Railroad & Louisiana Department of Transportation

Location: New Orleans, LA

Date of Completion: June 2008

Boh Bros. constructed Phase II of the Huey P. Long Bridge project. Under Phase II, two areas of the bridge were relocated and modified to allow for future roadways for the new bridge approaches. On the East Bank of the Mississippi River, Boh Bros. constructed three new bridge piers to support the longer girder spans. The construction consisted of H-piles, temporary steel sheeting, concrete footings and caps. In order to ensure rail traffic throughout the project, Boh built temporary shoring to support the large structures. Boh removed three 78 foot and two 45 foot superstructure sections, as well as two existing towers. West Bank modifications required construction of two new concrete footings and columns to accommodate a steel cross girder. This cross girder will serve as the pier caps for future traffic.

Challenges: Some aspects of the project required closure of the railroad, impacting the east-west transit across the Mississippi. Precise coordination with the railroad led to a successful closure and erection of the members.

Project Description

Client: Louisiana Department of Transportation and Development (LA DOTD)

Location: Orleans and St. Tammany Parishes, LA

Date of Completion: Jan 2006

Boh Bros. was awarded the project by LA DOTD to serve as the prime contractor for the Emergency Repair of the I-10 Twin Spans (approximately 5.5 miles) over Lake Pontchartrain damaged by Hurricane Katrina.

Damage included 58 spans missing or partially submerged, 437 spans out of alignment, and numerous damaged pilings and concrete spalls. This project demonstrated our ability to manage and construct an extremely large, fast-paced critical project. Boh Bros. completed the critical east bound bridge repairs in only 29 days.

Major features: 90% self-performed, recipient of AGC Build America Award, delivered on-time and on-budget, and earned an early completion bonus allowed for Phase I by opening the eastbound span in 29 days.
