Line Section 1 is the first Light Rail Transit system in Arizona. Though delivered by the traditional hard-bid method, Kiewit had a large hand in redesigning the project and resequencing tasks after encountering more than 600 unknown obstructions in approximately 14 months of work.
The single largest contract in Caltrans history, the “Skyway Segment” replaced over 1.2 miles of the bridge's eastern span. Composed of precast sections, the new span rests atop some of the longest and largest diameter bridge piles ever driven in the Bay Area. The work, performed by a Kiewit-led joint venture, is a key part of a major seismic retrofit program.
This design-build project included widening 10 miles of two-lane roadway to a four-lane divided highway; six AASHTO girder wildlife bridges; and new construction or extension of 16 box culverts. The work included 1.7 million cubic yards of excavation; more than 200,000 tons of asphalt paving; 8,500 feet of culvert piping; and constructing a 2,000-foot-long runaway truck escape ramp.
The Central Mesa Light Rail Extension Project is a Federally-funded project consisting of approximately 3.1 miles double track alignment extending from the Central Phoenix/East Valley LRT project’s eastern limits to an end of line station on Main Street between Olive and Ashland, Mesa.
In November 2007, Kiewit completed structural improvements to the Verrazano-Narrows Bridge, located at the mouth of Upper New York Bay. The $68 million project included removing aluminum anchorage access plates at the lower-level roadway and sealing the openings with concrete; installing steel maintenance doors; and installing shielding panels at the underside of the deck and on the main cable strands inside the anchorage walls.
Nearly 2 miles of Interstate 25 and Interstate 40 interchange were reconstructed and expanded under this $237 million contract. As part of the project, 55 bridges were built including eight new precast segmental fly-over bridges, 33 new concrete girder bridges and four structural steel girder bridges. Ten bridges were rehabilitated.
For more than three decades, Kiewit has been constructing projects for the Vancouver Skytrain light rail system. Most recently, crews constructed several portions of guideway and elevated guidway on the Lougheed, Front Street and Grandview segments.
While working in a narrow corridor in downtown Dallas next to pedestrian and vehicular traffic, Kiewit finished this $58.6 million, 7,000-foot light rail project through downtown Dallas in November 1996. The project involved utility relocation; street and sidewalk reconstruction; installation of light-rail track; and construction of passenger stations.
Kiewit exceeded expectations by completing this fast-track project in just 10 months. By working simultaneously on three sections of the road, crews were able to maximize productivity and complete the project early. The reconstructed stretch of U.S. 11 provides a safer route for motorists with more lanes, expanded shoulders and extended merge lanes.
This $347 million replaced and widened portions of the 7,900-foot long Hood Canal Bridge — the world’s longest saltwater bridge. Kiewit-General, a joint venture, widened the bridge’s superstructure and replaced the concrete approach structures, steel transition spans, drawspan and east-half pontoons.
