Completed in 2003 by the Turman Construction Company of
Barboursville, the $2.8 million West
Buckeye
Bridge is believed by WVU wood technology research personnel to
be the world’s longest three-hinge timber arch structure.
In addition to its fiber-reinforced glue-laminated timber arch
and use of HPS, the single-span 149-foot bridge carrying
Monongalia County 39 over Dunkard Creek west of WV 7 has a deck
of fiber-reinforced polymer. Designed in cooperation with WVU,
with innovative funding from the Federal Highway Administration
under a special program to encourage new technology, the project
includes a handicap-accessible parking lot nearby from which the unique structure
can be viewed.
Providing two 11-foot lanes with four-foot
shoulders and a five-foot upstream sidewalk, the single-span
structure has a deck developed by a
Kansas City manufacturer and an arch developed by an Oregon manufacturer.
It provides a
16-foot vertical clearance above the deck and has 15 cables on
each side and three steel hinges - two at the points where the
floor beams are attached and one at the apex because of the
arch’s length.
