(1st/2nd Quarter 2004)
Vecellio & Grogan is making improvements to two
miles of roadway in New River National Park in Prince, WV, under a
contract with the Federal Highway Administration.
Crews are building five “pile lagging” walls
along the downhill side of the roadway to reinforce it. The walls are
constructed of steel “H” pilings driven vertically into the rock to a
depth of 10', with white oak timber laggings laid in place horizontally
to a height of 16'. Fill rock will be added behind the wall to complete
the reinforcement.
The project also includes drainage improvements.
An underdrain was laid beneath the swale on the uphill side, with
asphalt paving planned for sections of the swale with less than one
percent slope.
Crushed stone will be placed and compacted to
make the road’s surface.
The design-build project, performed in
conjunction with Engineering 2000, is due for completion in November.
