RALSTON VIADUCT
The Ralston viaduct replaced a 1,000-foot stretch of bridge and pavement along a four lane, divided arterial road connecting Ralston to Omaha at 84th Street. The project was scheduled in three phases between 2017-2019. The first half was completed ahead of schedule in 2017, and the final phase was completed in 2018.
10TH & SALT CREEK
We removed an existing bridge deck and replaced it with a new NU1600 super structure, which required the implementation of a temporary bridge spanning Salt Creek during construction. We also removed and replaced RCP pipes with new inlets and excavated into a levee critical area. Temporary measures such as crane mats and battered pile surveys […]
NEBRASKA HIGHWAY 133
Highway 133 between Omaha and Blair was a major roadway project that consisted of 900,000 cubic yards of earthwork, 310,000 square yards of pavement, and 15,000 linear feet of culvert and storm sewer. We completed the project in four phases to reduce impacts to travelers. Along with two additional improvement contracts, this project completed the […]
URBAN VILLAGE TRIANGLE
We completed the structural concrete work for a 106-space parking garage below three apartment buildings at the Urban Village Triangle. We also performed concrete work on the ground level commercial tenant space in one of the buildings. The structure consisted of cast-in-place foundation walls, precast columns, inverted T beams, hollow-core planks, and concrete toppings. The […]
UNION PACIFIC RAILROAD – GRAETTINGER & UNION/PLATTSMOUTH
In 2015, a Union Pacific Railroad bridge in Graettinger, Iowa, was failing due to limestone deterioration under 12 piers and needed repair. Using 50-ton hydraulic jacks and shore towers to jack up the steel spans, we removed the limestone piers and replaced them with new, precast sections. All repairs were performed between train traffic. In […]
WP-5 RESERVOIR (PRAIRIE QUEEN RECREATION AREA)
We created a new reservoir where farmland had previously existed to mitigate low land flooding that occurred downstream and caused damage to homes and businesses. The project consisted of a three-span bridge and an earthen dam, which created a 160-acre lake and recreation area. Project Quantities:• 500,000+ cu yards of dirt work• 8,000 linear feet […]
ANTELOPE VALLEY EAST LEG “BIG X”
“Big X” was a complex $24M bridge project over the mainline Burlington Northern Santa Fe railroad tracks. Located near the University of Nebraska, these tracks presented a very dangerous situation for students who crossed regularly for campus access. At 1,200 feet long and 100 feet wide, this massive steel girder bridge spans five sets of […]
WEST DODGE EXPRESSWAY
Vehicles traveling along W Dodge Road in Omaha, Neb., routinely faced significant delays due to heavy traffic. We constructed two-mile-long urban viaducts, carrying six lanes of traffic, 45 feet above “lower” W Dodge Road between 124th Street and the I-680 interchange. The project also included frontage roads to improve traffic flow. We initiated phasing changes […]
