Work on Interstate 70 for about 3.5 miles in the Glenwood Canyon that has caused westbound delays is about 40 percent done, the Colorado Department of Transportation and Truesdell Corp., the contractor on the $7 million job, report.
Crews will have finished paving on the left westbound lane and both lanes will be open for Labor Day weekend, though it will not be possible to pass or change lanes in the work zone.
The project consists of the rehabilitation of five bridge decks between mile marker 124.64 and mile marker 128.12.
Repairs include removal of existing asphalt and waterproofing membrane, which will be replaced by a thin-bonded polyester concrete overlay. Paving will extend into Hanging Lake Tunnel. Work is expected to conclude in late October 2014.
Westbound right lane paving will begin after Labor Day. Work on the eastbound lanes will start at the end of September. Deck repair work is done in conjunction with paving. Thirteen hundred feet of bridge rail replacement in the left westbound lane will be completed in October.
Very specific weather conditions are required to lay the concrete, including temperatures between 40 and 100 degrees and no moisture. Wet weather since beginning the project has hampered progress, but the contractor has added equipment and construction crews in order to finish work in October.
