A heavily-traveled tunnel on eastbound Interstate 70 in western Colorado is expected to reopen Wednesday after a six-month shutdown to repair a crack.
The two-lane bore was closed in late March because of the 70-foot-long crack in the ceiling.
The two-lane westbound bore has been handling traffic in both directions ever since.
After excavating about 30 feet of dirt from on top of the tunnel, crews added layers of concrete above and below the cracked slab.
The Colorado Department of Transportation says the final cost of the project could be about 6 million dollars.
The 4,000-foot-long Hanging Lake Tunnel was completed in 1992.
It's located about eight miles east of Glenwood Springs and 110 miles west of Denver.
On average, the two bores carry a combined 16,500 vehicles a day.
