PHILADELPHIA (CBS) — Philadelphia’s bike share program known as “Indego” which launched last April is proving to be a popular mode of transportation particularly on weekends near the cities historic attractions.

The mayor’s office of transportation and utilities said the numbers show Indigo bike stations near Independence Mall are some of the busiest in the city. They are three racks or stations on federal property including a stretch along Market near 5th streets.

Jane Cowley is the public information officer at Independence National Historical park. She says the city was grated permission to operate the program on park property.

“And we were happy to work with them on that. They do have a permit that allows them to install these bike racks and maintain them, the national parks service very much supports this idea of encouraging people to ride bikes safely around the city,” Cowley said. “We love that the city is becoming more friendly.”

There are about 600 Indego bikes with more than 60 stations position throughout the city with more planned for the future.
