Drivers planning to travel on Interstate 70 between Floyd Hill and Idaho Springs should prepare for significant delays as the Colorado Department of Transportation (CDOT) begins rock scaling and blasting operations starting today. This work is part of the ongoing Floyd Hill reconstruction project, which aims to enhance traffic safety by replacing bridges and realigning the highway for improved sightlines.
Over the next two years, motorists can expect traffic holds every 60 to 70 minutes during work hours, which are Monday through Thursday from 9 a.m. to 3 p.m. CDOT warns that these holds may last up to 20 minutes, but in some cases, delays could extend to 45 minutes as traffic clears.
During the rock scaling phase, westbound traffic will be held east of the Hidden Valley interchange (Exit 243), while eastbound traffic will be stopped west of the Veterans Memorial Tunnels. Following this phase, rock blasting will occur once daily, up to three times a week, with similar traffic holds in place.
County Road 314 and the Central City Parkway will remain open during the scaling operations, providing some alternative routes, although CDOT advises that there are no official detour routes for I-70 traffic.
Travelers are encouraged to plan their trips around the scheduled work to minimize delays. For the most up-to-date information, CDOT offers text alerts; drivers can sign up by texting ‘floydhill’ to 21000. Additional resources include the project information line at 720-994-2368 and the project website at codot.gov/projects/i70floydhill.
As construction progresses, CDOT emphasizes the importance of safety in work zones. Drivers are reminded to adhere to posted speed limits, stay alert, and avoid distractions while on the road. The agency also recommends allowing ample space between vehicles and being prepared for potential lane shifts.
In summary, with rock scaling and blasting activities set to continue through 2026, drivers on I-70 should stay informed and patient as these essential improvements are made to enhance travel safety in the area.
