A national asphalt and polymer shortage may delay some highway projects in Colorado this summer.

Stacy Stegman with the Colorado Department of Transportation said in a news release to 7NEWS, CDOT is "reviewing its 2008 summer highway projects to identify those that may be impacted and what actions should be taken."

The asphalt shortage is expected to be short-term, but could affect 34 of CDOT’s projects this summer.

Stegman said "priority will be given to projects on more heavily traveled routes, areas with the most significant pavement damage or those in the middle of construction."

Among the options; delaying work until next year, extending project completion time, using a different pavement material/design or partially completing a project until additional asphalt can be secured.
