Rock and Rolling on the road

Another landside occurred on the Glenwood Canyon in Colorado yesterday. By a stoke of luck, the section affected by the landslide was already closed off due to an accident a few miles away. This incident isn't uncommon. In the 12 years that I-70 has been in existence, there have many accidents with falling rocks, some of which have been fatal. However, this isn't the only section of highway in Colorado that is affected by landslides. Almost all of the mountains roads show scars on the road where falling boulders have hit the road. The Colorado Department of Transportation has invested millions of dollars into landslide prevention with the use of barriers and intentional landslides to release loose debris. Unfortunately, some of CDOT budget must be used for crumbling roads and avalanche prevention, so a 100% committment is impossible.
So when you see the sign, "watch for falling rocks," you should really listen.
