As winter approaches, drivers on eastbound I-70 at Floyd Hill should prepare for seasonal detours caused by blinding sun glare during morning hours. These yearly safety detours will start in November, with closures likely to occur from sunrise to mid-morning, potentially adding an hour to travel time. In addition to the sun glare-related detours, full overnight closures are planned this month for ongoing construction projects at Floyd Hill, which are part of efforts to address $2.25 billion in congestion costs.
