The Chicago Transit Authority is looking at a plan to add more service to some of its routes, while completely cutting others.

The proposal aims to reduce crowding and meet the demands of growing ridership.

CTA spokesman Brian Steele says 12 bus routes are marked for elimination. He says the possible cuts are based on very low ridership numbers.

“Fewer than 100 the entire day,” Steele said. “And there are actually some routes, portions of routes that we’re looking at discontinuing that have fewer than 25 people on an average weekday. So really the whole goal is to ensure that supply is meeting demand,” he continued.

Steele says most of those bus lines have another transit option along the same route.

The CTA will hold a public hearing at its headquarters September 4 to discuss the proposal.

The agency wants to make the changes by December 16.
