Ski traffic jams on Interstate 70 are a perennial complaint from people in Denver. But the Colorado Department of Transportation says the ski jams are something of a myth - the highway's actually more congested in summer.
The department says that traffic data show the busiest month of the year at the Eisenhower & Johnson Tunnels for the past few years has been July.
In 2009, 39,536 drivers passed through the tunnels in July. August was the second busiest month with 37,577 drivers. March, January and February came next. October was the least busy month.
Summer holidays are worse, too. In 2009, the tunnel saw more vehicles on the Fourth of July weekend than during the Martin Luther King Junior holiday weekend.
