CHICAGO — Construction workers will soon start work on railroad tracks, station platforms, and the new north and south terminal buildings at Chicago Transit Authority’s 95th Street terminal. The work is part of the next major construction phase on the terminal's improvement project.

The work will require the agency to reroute certain Red Line trains for during off-peak ridership times on weekdays. Red Line trains south of Roosevelt Road will be rerouted onto the Green Line via the Ashland/63rd station. The agency plans to detour fewer than 10 percent of all Red Line trains during the construction work.

The $280 million project will transform the entire terminal area with upgrades to the interior of the facility and bolder architecture. The renovated station is on schedule to open later this year.

Construction workers are expected to start the next phase on April 2.
