Motorists traveling eastbound on Interstate 70 near Floyd Hill may face periodic morning closures over the coming months due to increased risk from sun glare. 

Beginning in early November through February, the sun’s angle can create a blinding glare for drivers due to inclining hills along the highway in the early morning hours, according to the Colorado Department of Transportation.

To minimize risk, safety closures are possible for drivers heading eastbound up Floyd Hill east of Idaho Springs around mile points 244 to 248. Intense sun glare can occur as far east as Genesee. Closures in the area typically average around 45 minutes and can occur between 6:30 a.m. and 8:30 a.m., according to the agency. 

In the event of a closure, eastbound traffic will be rerouted at Exit 244 for U.S. Highway 6, which is at the bottom of Floyd Hill. Motorists can either stay the course on U.S. 6 through Clear Creek Canyon or take the eastbound I-70 frontage road (U.S. 40) to get back onto I-70 at Beaver Brook.

Safety tips for driving in the sun include: 

• Wiping the inside and outside of windshields to make sure it is clean 
• Having ample windshield wiper fluid
• Wearing sunglasses to provide shade
• Adjusting speed 
• Slowing down gradually instead of slamming on the brakes

Closure decisions from November through February are made on a case-by-case basis each morning with collaboration between Colorado State Patrol and CDOT personnel who are stationed near Floyd Hill.
