August 31, 2012 - Central Eastern Colorado/CDOT Region 1 - SUMMIT COUNTY – Rock mitigation work gets underway along Interstate 70 next week, about three miles east of Silverthorne at mile 208, requiring daytime traffic stops for several days.

On Wednesday, September 5, the Colorado Department of Transportation (CDOT) will be stopping traffic once an hour for approximately 20 minutes on eastbound and westbound I-70.  The stops begin at 9 a.m. and continue until about 6 p.m.  Eastbound traffic stops at mile 207; westbound traffic at the Eisenhower Tunnel.

Traffic stops continue on Thursday, September 6, and Friday, September 7, on westbound I-70 only.  Drivers should anticipate 10 minute traffic stops throughout the day, from 7 a.m. until 6 p.m. Thursday, and 7 a.m. until noon on Friday.

The westbound traffic stops resume on Monday, September 10, during the same hours, and continue each day through Friday, September 14.
