Until
November 1998, economic development of some of the best
land in West Virginia was hindered by the lack of a Kanawha
River crossing
within 32 miles of Buffalo.
Providing a direct connection from a new US 35 upgrade to
I-64, the Lower Buffalo Bridge is a testimony to West Virginia’s
ability to meet the challenge of conceptualizing, clearing major
environmental hurdles, designing, permitting and constructing a
major river structure in only 30 months--in time for a new
Toyota manufacturing facility to begin shipping state-of-the-art
engines.
Necessary clearances, handled in record time by the
Division of Highways’ own environmental section with aid from
its consultant, involved spanning areas of known archaeological
deposits and assuring that remaining foundation locations would
not disturb others. In similar time, Highways’ bridge staff and
its consultant, with assistance from FHWA and others, designed
and prepared construction documents.
Cooperation from steel fabricators and shippers allowed
successful delivery of large and unwieldy box girders containing
3,500 tons of steel to the bridge site by summer 1998 to
contractor National Engineering and Contracting Company of
Strongsville, Ohio, which had piers and foundations ready for
the structure. With cooperation of the Coast Guard, all river
traffic was halted for two eight-hour periods so that the
segments assembled on barges-each 475 tons, 435 feet long, 13.5
feet deep and 10 feet wide-could be hoisted 70 feet to mate with
superstructure ends cantilevered 45 feet out from the river
piers.
With a twin haunched steel box girder superstructure supporting
two 12-foot lanes and six-foot shoulders and a total length of
1,850 feet, the Lower Buffalo Bridge is one of the longest
continuous steel box girder bridges in the United States, and
its 525-foot center span ranks third for its type nationwide.
The bridge also boasts electric lighting inside the box
girders to aid bridge inspection teams. |
