Coal Creek Road is the main arterial connecting the Coal Creek and Eufaula Heights communities with the City of Longview. Castle Rock Residents also travel up Coal Creek Road each day for a more direct route home. The unimproved road was narrow and windy. Intersections with Harmony Drive and Bergly Lane had excessive skew and poor sight distance. Vehicles could not turn right onto these roads without crossing into opposing traffic. The Coal Creek Road Reconstruction Project provided 6-foot wide paved shoulders and realigned the intersections, for a great safety improvement.
Widening Coal Creek Road was a difficult task. Several houses are close to the road. Coal Creek parallels the road at the bottom of a steep slope. On the other side of the road, the slope continues uphill for hundreds of feet. The final alignment threaded the needle, minimizing impacts to private property and the environment.
Several geotechnical issues were addressed by the project. A buttress landslide repair was reconstructed as part of the project. Slide movement occurred at the Coal Creek Road/Harmony Drive intersection during the heavy rain event of January 2009. As a preventative for future major sliding, horizontal drains were installed to stabilize the slope. This extra work was funded through the FHWA ER program.
