1, 2, Shift

Heads up motorists! On July 18, motorists will notice the first shift which will move all three lanes of eastbound I-70, between Brighton and Colorado boulevards, south into their new and permanent alignment. These new lanes will run underneath the newly constructed portion of the eastbound half of the cover park. 

At this time, after four years of construction, the Project will reach substantial completion as all lanes along the 10-mile stretch will be in final alignment. Express Lane testing will continue, and this additional lane (one in each direction) will continue to open in phases along the corridor.

Frequently Asked Questions (FAQ)

The Express Lanes between Washington Street and Colorado Boulevards will open in phases for testing throughout the next few months.

All on- and off-ramps to eastbound I-70 between the closure points will be closed 10 p.m., Friday, July 15, to 5 a.m., Monday, July 18.

Motorists should be prepared for the potential of slower traffic while entering the lowered section as folks become adjusted to the new environment. The lowered section, and tunnel in particular, is intentionally designed to allow for normal flow of traffic without encouraging slower traffic. CDOT strongly suggests motorists to continue flowing at a normal speed through the lowered section to prevent crashes or unnecessary congestion.

Westbound I-70 traffic will stay in its temporary alignment as crews work to remove the barrier that once separated east and westbound traffic in the future westbound lanes. Once the barrier is removed along I-70 this fall, crews will place final pavement and will move traffic into its final alignment on westbound I-70 between Brighton and Colorado boulevards.

The speed limit on I-70 between Brighton Boulevard and Chambers road will remain at 55 mph.
