Pace has added more buses to the popular bus-on-the-shoulder express service.
Special express buses travel on the shoulders of the Stevenson Expressway during designated times.
Beginning today, riders will have more options to use the rush-hour service from the Southwest suburbs to downtown Chicago and the Near West Side.
Pace officials began the service in 2011 and they have had such success they added additional trips.
A special later evening trip on Route 755 also will be added, serving Metra Heritage Corridor stations on an on-demand basis, Pace said.
Changes to stops during the evening rush are expected to reduce travel times as well.
Service changes for Route 755 include a doubling of the number of rush-hour trips from two to four in each direction.
The route runs from Plainfield and Bolingbrook to the Illinois Medical District and the University of Illinois at Chicago.
A new, midday round trip and a late evening trip have been added to shuttle passengers to the Pace Old Chicago Park-n-Ride in Bolingbrook.
Stops are made upon request at the Metra Heritage Corridor stations in Lemont and Lockport and at Joliet Union Station.
