ASBI Awards Three Top Honors to T.Y. Lin International
T.Y. Lin International (TYLI), a globally recognized full-service infrastructure consulting firm, has received three awards from the American Segmental Bridge Institute (ASBI). The Mike O’Callaghan-Pat Tillman Memorial Bridge/Hoover Dam Bypass; the I-64 Kanawha River Bridge; and the Jiayue Bridge all received ASBI’s “Bridge Award of Excellence.” The "Bridge Awards of Excellence" were presented at the ASBI 23rd Annual Convention 2011 held on November 7-8 in Washington, DC.
The ASBI Bridge Awards of Excellence recognizes the Owners of bridges that exemplify concrete segmental bridge design and construction excellence. Judging criteria included innovation of design and construction; aesthetics and harmony with the environment; cost competitiveness; and minimization of construction impact to the traveling public.
“These awards reflect the kind of ingenuity and determination in pushing the design envelope that TYLI is known for,” said David Goodyear, Senior Vice President and Chief Bridge Engineer. “We are very pleased that our progressive clients have been honored by ASBI in recognition of their achievements with these outstanding bridge projects.”
About the Award-Winning Projects:
I-64 Kanawha River Bridge, Kanawha County, West Virginia
The Kanawha River Bridge is a record-setting, low cost, and aesthetically pleasing structure built as part of the I 64 Widening Project. The overall bridge length is 2,975 ft, including a record 760 ft main span. The segmental box girder structure crosses over railroad tracks, Dunbar Avenue, the Kanawha River back channel, Wilson Island, the Kanawha River main channel, Riverside Drive, and MacCorkle Avenue. TYLI was the prime consultant providing design and construction support services for the West Virginia Department of Transportation, Division of Highways. The superstructure was built using the balanced cantilever construction method with cast-in-place segments supported by form travelers. Bridge construction was completed on schedule and the structure was opened to traffic on July 31, 2010.
Jiayue Bridge, Chongqing, China
The new Jiayue Bridge crosses the Jialing River near the town of Yuelai, Chongqing in China. It is a signature “Y-shaped,” partially cable-supported girder bridge carrying six lanes of traffic on its upper deck and two pedestrian/bicycle paths beneath the roadway wing slab. With a main span of 820 ft, the aesthetically unique and economically constructed bridge represents a new landmark and is the latest in urban development efforts for Chongqing’s northern area. It completes the City’s road network, ensuring smoother, safer passage for all travelers, and complementing the surrounding landscape. The Owner of the Jiayue Bridge is the Chongqing Land Properties Group. TYLI was responsible for all design components of the bridge. The completed bridge was opened to traffic to great applause on February 11, 2010.
Mike O’Callaghan – Pat Tillman Memorial Bridge/Hoover Dam Bypass, Clark County, Nevada and Mohave County, Arizona
A dramatic new concrete arch joins the setting of the historic Hoover Dam, spanning the Black Canyon between the States of Arizona and Nevada. The 1,900-ft-long Colorado River crossing is the centerpiece of the $240 million, four-lane Hoover Dam Bypass Project. The project includes 3.5 miles of new approaches on both sides of the river and seven other bridges. The Program Manager for the project was the Central Federal Lands Division of the U.S. Federal Highway Administration (CFLHD). The project design team was comprised of HDR, Jacobs Engineering, and TYLI. TYLI led the design of the landmark Colorado River span which is the highest and longest, single-span concrete arch bridge in the Western Hemisphere and features the tallest precast segmental columns in the world. The innovative hybrid structure is designed to complement the dam with a high-performance concrete arch while limiting the load demands with a modern steel superstructure. It is the first steel-concrete hybrid arch bridge in the U.S. The bridge officially opened to traffic on October 19, 2010.
