Work began on the overlay project in late July 30. It was a two-phase project.
Here's some background on the project. Obviously, ignore the information about the lane-closings since the construction is over:

Traffic will be restricted to two 11-foot lanes with a posted speed limit of 45 mph through the project work zone. As well, the ramps from Washington Boulevard eastbound I-70 and from Fairfax Avenue to eastbound I-70 will be closed will be closed during phase one work. A marked detour will be provided. Traffic will detour via Minnesota Avenue to eastbound I-70.
For phase two of the project, eastbound I-70 will be closed at 3rd Street, 24/7 round the clock, for the duration of the project. A marked detour will be provided. Traffic will detour via 3rd Street to Minnesota Avenue then back to eastbound I-70. Traffic will remain in two open lanes (two lanes closed) across the Lewis and Clark Viaduct. Traffic will continue to be restricted to two 11-foot lanes with a posted speed limit of 45 mph through the project work zone. The ramp from Washington Boulevard to eastbound I-70 will remain closed. Advance notification will be sent under separate cover when phase two of the project begins.
