6851-18 - Lower Fourmile Canyon Drive - Boulder Canyon Drive to Salina Junction

The Lower Fourmile Road project is part of the permanent repairs and improvements for flood damage work being performed by Boulder County.  The Lower Fourmile Road project is divided into two segments, south and north portion.  The south portion starts at Poorman Road and goes downhill approximately 5/7 of mile. And the north portion starts below the Salina Junction and goes downhill about ¾ of mile. The proposed  improvements on Fourmile Canyon Drive include a 27 foot wide typical roadway section consisting of paved roadway with two 11 foot lanes and two 1 foot downhill and 4 foot uphill shoulders. Roadside drainage is incorporated to convey runoff from roadway and ditches to culverts that outfall to Fourmile Creek.  The project includes the construction of retaining walls on the creek side of the road to support the road and roadway embankment.
