This $3.7 million project provided emergency repair to the eastbound and westbound Interstate 20 bridges in just 56 days. Vast resources, proper staffing and equipment allowed Kiewit to repair the bridges 10 days ahead of schedule and restore traffic to this major trucking route.
The Second Avenue Bascule Bridge in downtown Miami is the third largest drawbridge in the U.S. and the fourth largest in the world. The project was constructed to alleviate traffic and expand the channel for ships. The $47 million, two-year project involved replacing both halves of the twin, 3,000-ton, 300-foot-span bascule bridge.
Using a 1,270-milimetre-thick ice bridge for access, Kiewit completed the final pier on this $3.2 million, four-span steel girder bridge in September 1993. The 280-metre-long by 11-metre-wide bridge provides a link from a newly constructed pulp mill to vital timber reserves in northern Alberta.
The $629 million Tacoma Narrows Bridge is the first long-span suspension bridge to be constructed in the United States since 1964. Completed in July 2007, the 5,413-foot-long bridge includes a high occupancy vehicle traffic lane; a separated bicycle/pedestrian walkway; an 8,000-square-foot toll plaza building; and configurations for a future secondary roadway or transit deck.
Age, heavy traffic and the effects of weather led to the New York City Department of Transportation's decision to replace the Willis Avenue Bridge with a new swing bridge. The $644 million project included construction of the new bridge and approaches and demolition of the existing bridge when the new bridge is open to traffic.
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.
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.
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.
