The Colorado Department of Transportation (CDOT) announces extended closures of Interstate 70 Glenwood Canyon from 9 a.m. to 3:30 p.m. on Wednesday, Aug. 10 and Thursday, Aug. 11, for both eastbound and westbound traffic.
CDOT says the closure is necessary so it can use a helicopter at mile point 124.2, just west of Hanging Lake Tunnel for rockfall work.
According to a statement on the department’s website, “… the eastbound closure point is at Exit 116 (Glenwood Springs), and the westbound closure point is at Exit 133 (Dotsero). Colorado State Patrol will assist with traffic mitigation, and all vehicles must exit; queuing will not be allowed.”
The department urges travelers to drive through the Glenwood Canyon before 9 a.m., or wait until the canyon is reopened at 3:30 p.m., and anticipate heavy traffic at the beginning and end points an hour before and two hours after reopening due to vehicle congestion.
Commercial Vehicle Routes:
CMV parking will be available at Exit 133 (Dotsero). The following width restrictions are in place on several of the alternate routes:
- CO 131: 8-foot width restriction
- CO 9 north of I-70: 12-foot width restriction
- CO 13: 10-foot width restriction
CMV are restricted from using Independence Pass, which has a 35-foot length restriction in place. On the Exit 116 Glenwood Springs side of the closure, Colorado State Patrol will be working to stage CMV on I-70. Please pay close attention to all traffic control in place and follow flagger instructions.
Cottonwood Pass, Frying Pan Road and Hagerman Pass are not recommended alternate routes.
