CDOT to test using lights to control I-70 traffic
DENVER – CDOT is going to try using traffic control lights to regulate the flow of traffic on Interstate 70 at the Eisenhower tunnel this winter.
The lights will be familiar to any metro area commuter who tries to get onto I-25 during rush hour.
The lights will be placed on the west side of the tunnel. They will cycle every four to eight seconds so that vehicles will only have to stop briefly before being allowed to enter the tunnel.
CDOT will use flags for the first test on Dec. 8. If the program works well, they will install permanent lights.
