I-20 Augusta Rehabilitation

Augusta, Ga.

Completed nearly one year ahead of schedule, the $28 million I-20 Lane Replacement project involved replacing 13 miles of east and westbound Interstate 20. Additional work included roadway demolition and shoulder widening while maintaining traffic through this heavily traveled corridor.

Leonard P. Zakim Bunker Hill Bridge

Boston, Mass.

Constructed by a Kiewit-led joint venture, this $100 million, 10-lane Leonard P. Zakim Bunker Hill Bridge is the world's widest cable-stayed structure. The new bridge opened to traffic in March 2003 and is the highlight of Boston's multi-billion dollar “Big Dig” Central Artery/Tunnel project.

The BART Warm Springs Extension DB project consists of furnishing all management, coordination, professional services, labor, equipment, materials and other services to perform the design and construction of the line, track, station and systems required to extend the BART System further into southern Alameda County from the existing Fremont BART Station to the new Warm Springs Station.

I-26 Mars Hill

Madison County, N.C.

The Interstate 26 Mars Hill project was designated North Carolina's first interstate scenic byway. This 6-mile project involved extending I-26 through the Appalachian Mountains and performing 24 million cubic yards of excavation. At the time of its completion in April 2002, this 64-month project was the largest ever undertaken by the North Carolina Department of Transportation.

Metro Gold Line Foothill Extension

Pasadena to Azusa, Calif.

This $503 million design-build project was awarded to Foothill Transit Constructors, a joint venture between Kiewit and Parsons. The project includes final design and construction of 11.5-miles of double light rail main track, 14 new bridges, eight modifications to existing bridges, six stations, three center platforms, three side platforms and a maintenance and operations facility.

Netnak Bridge

Cross Lake, Man.

The $17 million Netnak Bridge project included the construction of a five-span, 262-metre-long by 11.2-metre-wide bridge over the Nelson River in northern Manitoba. Three river piers were also constructed in cofferdams up to 17-metres deep.

I-40/Coors Interchange

Albuquerque, N.M.

With Albuquerque's population growing, the I-40/Coors Interchange could no longer accommodate the daily traffic volume. The design-build project to rebuild the heavily traveled roadway included the interchange reconstruction, eight new bridges, pedestrian and bicycle paths, retaining walls, utility relocations, drainage improvements, signage and lighting.

Bay Bridge SAS E2-T1 Foundations

Oakland, Calif.

A Kiewit-led joint venture constructed the Bay Bridge SAS E2/T1 project. The scope of work involved building the foundation of the self-anchored-suspension 530-foot-tall tower, known as the T1 footing, and constructing the eastern-most support structure, or E2, for the Skyway Segment. The three-part E2 structure is 220 feet long by 80 feet wide and the footing structure is 85 feet long, 73 feet wide and 21 feet thick.

Laval Metro Rail Installation

Montreal, Qué.

As part of the extension of the Montreal metro to Laval, the Agence Métropolitaine de Transport awarded a $35.5 million contract for track and switchgear installation to a Kiewit-led partnership. Crews completed the work in 16 months, two months ahead of schedule.

I-5 and Highway 217 Reconstruction

Tigard, Ore.

Using an A+B contract, the Oregon Department of Transportation selected Kiewit to reconstruct the intersection of Interstate 5 and Highway 217. This $38 million project relieved traffic congestion as exiting northbound I-5 traffic attempted to merge with the heavily traveled Highway 217, which provided the only freeway access into western Portland. The reconstruction work involved merging northbound I-5 with westbound Highway 217 via a fly-over ramp.
