Fewer vehicles used Interstate 70 through the Eisenhower Tunnel last year than in 2009, the second time traffic through the tunnels has declined in the past three years, according to the Colorado Department of Transportation.
The count for 2010 was 11,391,704 vehicles, down from 2009 by 343,658 vehicles or a 2.9 percent decrease.
In 2008, traffic dropped from 2007 by nearly 225,000 vehicles.
In 2009, tunnel traffic increased by 184,761 trips, to 11,735,362, CDOT said.
Tunnel supervisor Mike Salamon said some of the decreased traffic might be due to carpooling.
“The park-n-Ride lots, like those at the Hogback (I-70 and Morrison Road), are very full on weekends,” he said. “It’s not scientific by any means, just an observation.” Howard Pankratz, The Denver Post
