Motorists stuck in Colorado highway traffic during ski season are getting a new option this winter to bypass traffic – for a price. Colorado is converting a highway shoulder lane on I-70 into an express lane. The 13-mile toll lane will have flexible pricing, as high as $30. Interstate 70 is a major corridor to Colorado’s ski resorts. On winter weekends, skiers can face long delays driving back home. Colorado’s toll idea is unusual because it would apply mostly to recreational travelers. Other places have pricey express lanes that cater more to workday commuters. Colorado highway officials point out that the toll wouldn’t go to $30 except in the worst traffic. The agency is planning public hearings this week to get feedback.
