BUILDING AMERICA'S INFRASTRUCTURE
Huey P. Long Bridge Widening, New Orleans, Louisiana The Huey P. Long US 90 Bridge over the Mississippi River is a key infrastructure component of the New Orleans and Louisiana economies, with 50,000 vehicles daily, along with passenger and freight train usage. Completed in 1935, the steel truss bridge supports 2 railroad tracks, and 4 narrow 9 feet wide traffic lanes. The project added trusses on each side and replaced the existing traffic lanes with 3 widened lanes and shoulders. The main span is 2,375 feet long in 4 spans. The widening scope included over 17,000 tons of structural steel, and extensive retrofitting of the existing trusses to accept connections to the new trusses. Extensive work procedures were also employed at the road deck level to maintain the normal 4 lanes of traffic and rail usage as much as possible. The retrofitting and connection work on the existing trusses was performed from fixed work platforms, and also moving platforms over the traffic lanes. .
BUILDING AMERICA'S INFRASTRUCTURE - BILOXI
U.S. Highway 90 Bridges across Biloxi Bay, Biloxi, Mississippi This project consisted of removing and replacing the U.S. Highway 90 Bridge across Biloxi Bay, which was destroyed by Hurricane Katrina. The project included the design and construction of a 1.6-mile long divided bridge, providing six lanes of traffic across the bay on a nearly parallel alignment to the old bridge. Work included the demolition and removal of the existing bridge and roadway debris. It also included the demolition and replacement of an 800-foot long bridge over the CSX Transportation Railroad and associated embankment, roadway and electrical items. In addition to the bridge scope, the project included reconstruction of the foreshore protection along the bay's shore. This project required the use of 20 floating cranes, six land based cranes and an average of 240 personnel working six days a week. This large equipment fleet was mobilized quickly because the majority of equipment was owned by the joint venture partners, with much of it in the gulf coast region. The work included driving 105,000 linear feet of concrete piling, installing 10 million pounds of reinforcing steel, erecting 90,000 linear feet of precast concrete girders and placing 72,000 cubic yards of structural concrete. Waterline footings required sealing of footing forms around driven pile and dewatering of the form to place footing concrete. Seventeen months after contract award, soil borings, geotechnical design, bridge design, all permitting, test pile program, access dredging and complete construction of one of the bridges across the bay was complete. The project team achieved a very aggressive schedule and completed the project 45 days early. Completion of the second bridge and all associated work for final acceptance was completed just 22 months after contract award. The utilization of resources by the joint venture partners and the partnering relationship with MDOT and FHWA made this possible. The efforts of the project team were recognized when they received AASHTO's 2008 America's Transportation Award in the category of Large Project - Innovative Management, and further honored by the FHWA with the Award of Excellence in 2008.
BUILDING AMERICA'S INFRASTRUCTURE
Steel Port Facility, Convent, Louisiana Massman completed the construction of the Nucor Steel Louisiana LLC ship unloading/barge loading dock facility on the Mississippi River near Convent, LA. The facility offloads ocean going ships loaded with iron ore. The iron ore is transferred to a processing plant on land by a conveyor system. After processing the ore, the reduced iron is returned to the dock facility for loading onto barges for shipment to other steel mills which produce steel plate and shapes. The project included the installation of the foundations for the offloading and loading structures, construction of reinforced concrete decks for conveyor transfer and hopper buildings, and installation of guidewalls and mooring dolphins for both ocean going ships and inland barges.
BUILDING AMERICA'S INFRASTRUCTURE - MRB
I-70 Stan Musial Veterans Memorial Bridge, St. Louis, Missouri A Massman led joint venture constructed this award-winning cable-stayed bridge across the Mississippi river in St. Louis, Missouri. This project was completed for Missouri Department of Transportation on budget and schedule. The cable-stayed portion of the project consists of a 1,500 foot long main span (the third longest in the US) with two 636 foot long end spans. Each of the two main (river) piers are founded on six 11’-6” diameter drilled shafts with 11’ diameter rock sockets. The 400 foot tall delta shaped piers support the superstructure with 34 pairs of stay cables. When completed, the new bridge will carry two lanes of Interstate 70 traffic each way between downtown St. Louis and the Metro-East. (Rendering courtesy of MoDOT)
