Best of 2005 Awards
World War II Veterans Memorial Highway
- Bennington-Hoosick Bypass
Award of Merit: Highway and Roadway
In limbo for more than 40 years due to political and budgetary
difficulties, the World War II Veterans Memorial Highway,
also known as Vermont Rt. 279, finally opened to traffic in
July.
The 5-mi.-long road has a 1.4-mi. section in New York and
proceeds northeasterly through pristine Vermont wilderness
to just north of downtown Bennington. Almost a third of the
work took place in New York.
The Vermont Agency of Transportation awarded Clough Harbour
& Associates of Albany, N.Y., an initial design contract
in 1993, launching a 12-year project that aimed to preserve
the area's aesthetics and limit harm to wildlife. The design
took up most of the early years because of the need to address
various ecological concerns, while the construction portion
took place over the last five years.
The project cost $56 million, including a core construction
budget of $33.4 million, and involved:
- displacement of more than 500,000 cu. yd. of soil and
rock
- construction of six new bridges, including a 860-ft.,
five-span, curved-girder bridge over the Walloomsac River
- rehabilitation of six existing bridges
- and construction of a multidirectional interchange at
the eastern terminus.
The remainder of the project budget included costs for wetland
mitigation, site construction, consultant fees, and agency
expenses.
"It was well orchestrated, well done," said one
of the Best of 2005 judges.
Another added, "It was a lot of work for the money."
Environmental concerns and the location of historic bridges
and monuments in the area strongly influenced the project's
sequencing. To showcase the area's natural beauty, engineers
designed the road to provide motorists with stunning views
of the rolling terrain.
The project required a broad cooperative partnership with
all stakeholders. At times, the project's consultants had
to foster compromise between various reviewing agencies with
competing goals. For instance, the project had to meet the
standards and environmental-protection rules for both New
York and Vermont.
"It's a community involvement job," one of the
judges added. "You've got a lot of Sierra Club types
up there."
The engineering team designed the road to avoid significant
excavation and instead have flat horizontal curves on tall
embankments. The design called for the embankments to blend
into the terrain by extending earthen slopes and taking advantage
of the densely wooded area. The team created before-and-after
artistic renderings to demonstrate that the alignment would
also shield nearby residences from looking onto traffic.
The design of the bridge crossing the Walloomsac River required
extensive flood-plan features and accommodations for variable
river channel conditions. The team designed rounded pier configurations
and skewed pier alignments to optimize channel and floodway
performance.
During construction of the bridge deck, contractors ran four
concrete pumps simultaneously to limit the number of joints
in the structure. The team installed a textured, high-performance
bare concrete surface on the deck's 5 percent vertical grade.
The engineers also identified a deer wintering habitat in
the vicinity. To decrease the likelihood of animal incursions,
the team designed two other bridges and a culvert near the
middle of the highway to allow deer and other woodland creatures
to pass under the structure. That strategy, which required
building longer structures than otherwise necessary, also
made the stream banks more hospitable to amphibian life.
Crews also used onsite natural resources whenever possible.
They crushed bedrock from a 2,000-ft.-long, 70-ft. high-excavation
and used it for the road sub-base, stone fill, and underdrain
stone.
All heavy equipment, along with steel and cement deliveries,
came onto the site from either end of the project, where the
bypass connects to highways. The contractors established well-defined
heavy vehicle routes outside of populated areas to minimize
traffic congestion and damage to streets. The strategy avoided
the need for heavy equipment and deliveries to maneuver through
tight spaces on local roads and on covered bridges, while
also working around weight limits on nearby bridges.
