Three segments of Interstate 25 should be expanded to six lanes by June, project officials said during a Thursday news conference.
The stretch of highway from Woodmen Road to InterQuest Parkway is expected to be finished by June, with the short Woodmen to North Academy segment expected to be completed by May.
The other six-lane stretch that could be open by late June is from the bridge at Black Squirrel Creek — where the median widens — to just north of North Gate Boulevard. The bridge over Black Squirrel Creek, which is about 50 years old, is being replaced.
The other two segments will be widened between July and October, with the North Gate interchange to be reconfigured during mid-summer. Work will begin March 4, mainly on improving drainage near the roadway. Barriers to separate workers from motorists should appear by the third week of March.
The four existing lanes of I-25 will not be closed during peak travel times but intermittent closures may occur from 8:30 p.m. to 5:30 a.m., with reduced speeds to 45 mph.
The five segments are:
• Woodmen to Academy
• Academy to InterQuest
• InterQuest to north of Black Squirrel Creek
• North of Black Squirrel Creek to north of North Gate Boulevard
• North of North Gate interchange to Highway 105 in Monument
Segments 1, 2 and 4 will be widened toward the median, with the other two widened toward the highway’s outer edge.
Although Kiewit Infrastructure Co. said in its bid it would complete work by December, the mandatory completion date is a year later, by the end of 2014.
The job will cost $66.4 million. The Colorado Department of Transportation kicked in $50.4 million, with the Pikes Peak Area Council of Governments chipping in $8 million, and another $8 million coming from the Federal Highway Administration.
During peak construction times, Kiewit will employ 200 workers. An estimated 200,000 work hours are expected to finish the job.
Colorado Department of Transportation project manager Dan Hunt said the biggest goal is maintaining safety for workers and motorists.
“Construction is easy,” he said. “It’s not rocket science. It’s dirt and asphalt.”
McDonald cautioned drivers to stay focused while traveling through work zones, where speed limits will be reduced by 10 mph.
“Avoid texting, cell phones, eating and drinking,” he said. “People are driving through our office in those work zones and we want everyone to stay safe.”
