COPENHAGEN — Picture 11 miles of smoothly paved bike path meandering through the countryside. Largely uninterrupted by roads or intersections, it passes fields, backyards, chirping birds, a lake, some ducks and, at every mile, an air pump.

For some Danes, this is the morning commute.

Susan Nielsen, a 59-year-old schoolteacher, was one of a handful of people taking advantage of Denmark’s first “superhighway” for bicycles on a recent morning, about halfway between Copenhagen and Albertslund, a suburb, which is the highway’s endpoint. “I’m very glad because of the better pavement,” said Ms. Nielsen, who wore a rain jacket and carried a pair of pants in a backpack to put on after her 40-minute commute.

The cycle superhighway, which opened in April, is the first of 26 routes scheduled to be built to encourage more people to commute to and from Copenhagen by bicycle. More bike path than the Interstate its name suggests, it is the brainchild of city planners who were looking for ways to increase bicycle use in a place where half of the residents already bike to work or to school every day.

“We are very good, but we want to be better,” said Brian Hansen, the head of Copenhagen’s traffic planning section.
