Transportation planners want to use continuous flow metering at the tunnel, which will allow vehicles to keep moving through it gradually when there is a traffic slowdown. Traffic signals will be installed above eastbound I-70 on the west side of the tunnel and cycle every 4-to-8 seconds so that vehicles will only have to stop briefly before being allowed to enter the tunnel.
A first test of continuous flow metering will be conducted Dec. 8. If all goes well, the Colorado Department of Transportation wants to start it full-time for the holidays.
It would replace the current metering system of stopping all inbound vehicles from entering the tunnel until traffic back-ups clear, said Tony DeVito, CDOT's Region 1 transportation director.
"When continuous flow metering is used elsewhere there is a decline in the number of accidents," said DeVito.
