Drainage work set to begin on Casper Mountain Road

Date: 09/18/2009 


Crews with Hedquist Construction of Casper are set to begin drainage improvements along Casper Mountain Road (Wyoming 251) early next week (Sept. 28), weather permitting. The improvements may cause some traffic delays and bicyclists are urged to use caution or avoid the road during the expected two-week construction timetable.

Crews will dig a trench across Wyoming 251 just below the scenic overlook to install a drainage pipe. During this time, expected to last two to three days, the trench will be covered with gravel. As construction continues, large concrete sediment boxes (see below) will be installed at three different locations along the highway, requiring the use of a crane. The boxes will also be installed in the area below the overlook. Traffic will be delayed as the boxes are installed.
While crews will work to keep loose gravel from the highway, motorists and bicyclists using the road are cautioned that it’s likely that some gravel will remain on the roadway.
The drainage improvements are part of the American Recovery and Reinvestment Act (Federal Stimulus) at a cost of approximately $328,000.
Sediment Box – Sediment boxes feature a large chambers separated by barriers, or baffles, that trap sediments flowing with storm or spring runoff. The chambers are periodically cleaned out. They’re effective at reducing the amount of solids (sand, gravel) in the runoff. This area is prone to erosion and the collected sediment will be reused to maintain shoulders or on other projects. This is the first time sediment boxes will be used in WYDOT District 2.
