Median removal work on the southern portion of the Route 59 construction zone in Naperville is set to begin Monday, causing the city to warn drivers of lane closures and more traffic delays during the second month of the two-year project.
Overnight work between North Aurora Road and Aurora Avenue/New York Street is expected to take place the next few weeks as contractors from Martam Construction, Inc., of Elgin and K-Five Construction Corporation of Lemont remove the median and replace it with temporary concrete during the day.

Further north along the 3.5-mile stretch, crews are expected on Tuesday to close the connection to Route 59 from Dearborn Court. Naperville officials say the access point is one of a handful to be closed during the expansion project and not reopened once work is complete.
The construction efforts are part of a nearly $90 million project that will reconstruct and widen Route 59 in Naperville and Aurora to three lanes between Ferry Road and Aurora Avenue/New York Street. The project will improve traffic signal coordination and create extra left-turn lanes at Diehl Road, North Aurora Road, Jefferson Avenue/Liberty Street and Aurora Avenue/New York Street. One of the first "diverging diamond" interchanges in the state will be built where Route 59 meets I-88 to eliminate most left turns across opposing traffic and keep cars flowing more steadily.
A stormwater pumping station south of the Burlington Northern Santa Fe railroad tracks is being upgraded in conjunction with the road work, according to Naperville's transportation, engineering and development department. In October, once temporary medians have been installed in the southern portion of the road work zone, regular southbound outside lane closures will begin to allow work on the pump station to continue.
In another Naperville construction project, traffic will be reduced Monday to one lane in each direction on Washington Street between Osler Drive and School Street as crews grind and repave the road between 7 a.m. and 5 p.m. The 1.2-mile $800,000 project is expected to be complete by mid-October, but until then, parking on Washington Street in downtown Naperville is prohibited and drivers are encouraged to leave extra time or find alternate routes.
