Service on CTA Brown and Purple line trains returned to normal Monday morning after work crews rebuilding the Wells Street Bridge finished a major phase of construction.
Sometime around 4:30 a.m. the first CTA trains rolled across the bridge following a nine-day closure, the Chicago Department of Transportation announced.
Repairs on the 91-year-old bridge have caused headaches for commuters since March, when the first of two nine-day closures began. No more major CTA closures are expected as work proceeds on the $41 million project.
While much of the heavy lifting is out of the way, the lower level of the double-decker bridge will remain closed to motorists and pedestrians until November.
The bridge needed structural updates because of salt corrosion and weather-related wear and tear. It also received new electrical and mechanical components.
The affected CTA lines carry an estimated 77,000 commuters per day.
