Sprinkler system for I-70 expansion project could cost $5 million

DENVER — The Colorado Department of Transportation plans to put a sprinkler system under the cap of the Interstate 70 widening project.

The cap is a 1,000-foot section of I-70 between Columbine and Clayton streets that will be about 30 feet underground covered by a steel and concrete cover that will have a park on top of it.

CDOT said the sprinkler system will include heat detectors and cameras that would trigger the sprinklers when there are signs of a fire.

It’s the same kind of system recently installed in the Eisenhower and Johnson tunnels.

The $5 million was already included in the project’s $1.2 billion budget, according to CDOT.

Construction on the project, which will remove the dilapidated viaduct east of Interstate 25, is set to begin in 2018. ¬†Project leaders say it’s easier to install the system during construction instead of retrofitting the tunnel later.
