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.
The scope of work included demolition of the existing hopper bottom, metal roofed reservoir, the construction of a new 20 MG cast-in-place reservoir, installation of chemical feed piping, level sensors, transmitters and associated conduits and control wiring.
The 8-mile I-15 FasTrak™ program, located between Kearny Mesa and Rancho Penasquitos, allows single occupancy vehicles to pay a fee to use the high occupancy vehicle lanes. Since the program's inception, the average daily traffic on the carpool lanes has increased from 9,400 to 20,000 vehicles per day.
In less than 18 months, a Kiewit-led joint venture completed Phase I of the Greater Toronto Area's first bus rapid transit system. The team developed innovative design solutions to meet the project's technological challenges including real-time electronic bus arrival displays and a computer-aided dispatch transit control center with GPS.
The project team widened and reconstructed approximately 4.5 miles of the existing IH-30 from east of Loop 12 to Sylvan Avenue to four new lanes each direction. This $98 million project also involves reconstructing 11 bridges and constructing four types of retaining walls.
The $18-million Citizen and Immigration Services (CIS) Nebraska Service Center is a 144,000-square-foot, two-story office building completed under a design-build contract. CIS is LEED® Silver certified, and features a dual duct air distribution system which supplies fresh air continuously and separately from the conditioned air. The interior electrical system incorporates daylight harvesting along with motion and occupancy sensors to minimize consumption.
On January 1, 2011, Kiewit was awarded a contract to provide management services to mine and deliver lignite from the San Miguel Mine. Approximately 3.3 million tons of lignite coal is delivered to the adjacent 400-MW San Miguel Electric Cooperative, Inc. power plant, which is the owner of the mine. San Miguel Electric Cooperative, Inc. furnishes power and energy to Brazos Electric Cooperative, Inc. and the South Texas Electric Cooperative, Inc.
