Interactive Table:

Summary of Chicago bike lanes by type & length


  • This table shows bike lane miles have increased from 272mi to 341mi over the past four years.

  • Those 69 miles of additional bike lanes equal 17.25 miles added per year.

  • Most of this increase comes from additional painted bike lanes ("Bike lane" in the table) and new neighborhood greenways, which are traffic-calmed residential streets.

  • Additionally, 12.9mi of protected bike lanes were added.

  • It's important to point out, painted bike lanes offer little protection for cyclists, both neighborhood greenways, off-street trails, and protected bike lanes help keep cyclists safe.

Interactive Table:
Bike lane information for each Chicago ward

Sort the table above by its various columns to learn more about the wards.

  • For example, North Side wards 46-49 and 44 have the most bike lane miles compared to street miles with approximately 16-22% of their streets having bike lanes.

  • A subset of these, wards 49, 44, and 48, have the most miles of protected lanes and neighborhood greenways compared to street miles.

  • Meanwhile, 17 wards (more than a third) have no protected lanes or greenways.

  • In a majority of wards (56%), fewer than 1% of street miles have safe space for cyclists—a protected bike lane or a greenway.

  • The wards with the most logged bike lane obstructions are centrally located—for example wards 27, 42, 25, 4, and 2.

  • These five wards (27, 42, 25, 4, and 2) also had the most obstructions per bike lane mile.
