I commute 16 miles to work each day, covering the Officers Gulch area along I-70 from Copper Mountain to Frisco. The area is under the jurisdiction of CDOT snowplow Patrol 44 and Patrol 43. All winter, from October to April, the Recreation Path is closed due to snow cover and avalanche danger. Therefore, I ride the shoulder of the freeway. Generally, I leave work at 3:00 AM and ride down to work at 3:00 PM if on night shift and reverse that commute if assigned day shift.
Last week, CDOT snowplow driver 44-5, a recent hire, blocked the shoulder and attempted to pull me off the freeway and detain me to tell me that, "I shouldn't be on the freeway." After I passed him, he passed me, blasting his horn and swearing at me. I discussed the incident with the junior foreman for the area and explained that I do not have an alternative path to work.
I have seen several general references to the rights of bicyclists to the use of freeways where there is no alternative. Please provide me with specific citations or appropriate contacts to settle this issue. Thank you.
