Drivers navigating I-70 near Floyd Hill should expect ongoing disruptions through the end of this week as construction crews shift into a new stage of the project focused on building a major concrete segmental bridge.
The most immediate impact is an overnight full closure of eastbound I-70 at the bottom of Floyd Hill, between the US 6 interchange (Exit 244) and County Road 65 (Exit 248), running again tonight from 10pm to 4:30am. According to the Colorado Department of Transportation, crews are erecting a temporary framework system that will support construction of the future concrete cast-in-place segmental bridge, marking a visible new milestone in the multi-year project. Drivers will be detoured off at Exit 244 onto US 40 eastbound, rejoining I-70 at Exit 248.
A second round of overnight closures in mid-to-late April is also on the horizon, when crews will shift to the westbound side to remove a pier table in preparation for the next phase of bridge work.
Closer to Idaho Springs, rock scaling and blasting operations continue today through Thursday between the Veterans Memorial Tunnels and Homestead Road from 9am to 3pm There is no detour for this section. Plan for delays of up to 45 minutes as traffic queues clear after each hold, and CDOT recommends shutting off your engine during stops to help with air quality.
Daytime single-lane closures in both directions between Exit 248 and Hidden Valley (Exit 243) are also running through Friday for related construction and utility work. If weather interferes with any of this work, CDOT has flagged April 7 and 8 as backup dates. Drivers can monitor conditions at COtrip.org or text “floydhill” to 21000 for alerts before heading out.
The Floyd Hill project is overhauling eight miles of the I-70 mountain corridor between Evergreen and eastern Idaho Springs. Construction began in July 2023 and the full project is not expected to wrap until 2029.
