Chicago to Launch Dedicated Northbound Bus Lane on Michigan Avenue

Chicago is launching a dedicated northbound bus lane spanning 1.5 miles on Michigan Avenue between Roosevelt Road and Wacker Drive, a move designed to reduce delays for the approximately 22,000 daily transit riders who use the corridor.

The new transit corridor addresses a severe mismatch in street space usage during morning rush hours. While Chicago Transit Authority (CTA) buses carry roughly 35% of all passenger trips along Michigan Avenue, they account for only 3% of the total vehicles on the road, the city reported.

Painting work for the red-marked lane was delayed by rain, but the Chicago Department of Transportation (CDOT) expects installation of new pavement markings and signs to finish within seven to ten days.

How Chicago Puts Buses First on Michigan Avenue

The dedicated lane will operate exclusively on the northbound side of Michigan Avenue. Southbound lanes present too many logistical hurdles for rapid transit installation, as CDOT spokesperson Erica Schroeder explained that southbound stretches contain more curb cuts, loading zones, and competing curbside uses.

Assistant CDOT Commissioner David Powe noted that the lane will be modeled after the Loop Link system near City Hall, though it will omit cement bus platforms. While reserved for buses, the lane will still accommodate vehicles needing to make right turns.

To keep unauthorized drivers out of the path, the city plans to rely on its Smart Streets automated ticketing program. Powe stated that motorists blocking transit lanes in the downtown area receive an initial warning followed by fines on subsequent offenses.

“We believe smart streets will deter people from parking in these bus lanes along Michigan Avenue,” Powe said.

Why City Officials Back the Transit Priority Project

City leadership framed the new corridor as an essential upgrade for daily commuters who rely on public transit for work and school. Mayor Brandon Johnson said in a statement that the investment ensures residents can reach destinations reliably.

“Chicagoans depend on our buses every day to get to work, attend school, access essential services and connect with their communities,” Johnson said.

Acting CTA President Nora Leerhsen also championed the infrastructure upgrade, noting that Chicago has lagged behind some other major cities in total bus lane mileage. Leerhsen pointed out during a board meeting that New York maintains over 140 bus lanes, Los Angeles operates 100, and San Francisco features 40.

The project required coordination across multiple government bodies because Michigan Avenue falls under the jurisdiction of the Illinois Department of Transportation (IDOT). State transportation secretary Gia Biagi, CDOT commissioner William Cheaks Jr., and Northern Illinois Transit Authority interim executive director Jamie Rhee all praised the cross-agency collaboration.

What Transit Authorities Will Monitor Next

CDOT and the CTA will treat the northbound lane as a six-month pilot program. Authorities will track passenger usage, travel times, and overall operational impact to decide whether adjustments are necessary.

For regular commuters frustrated by parked cars obstructing transit stops, the project is a welcome intervention. Suragi Ragmi, a transit rider, described how blocked lanes previously forced passengers to run into active traffic to board buses.

“It is difficult. We need to go there just to get on the bus. So, we need to run there,” Ragmi said.

Whether the six-month evaluation period will prompt the city to expand dedicated transit corridors to the southbound side of Michigan Avenue—or across other congested city arteries—remains unaddressed by transit officials.
