Crews cutting Argyll Lane access to Route 59 in Naperville

Access from Route 59 to Argyll Lane in an unincorporated area near Naperville is scheduled to be cut off Monday as construction crews continue working to widen the congested state road.

Argyll, which is north of Bruce Lane on the west side of Route 59, is one of several small side streets and driveways that will be disconnected from the state road during a two-year $90 million widening and repaving project largely funded by the Illinois Department of Transportation.

Restricting access from streets such as Argyll aims to reduce congestion and improve safety along the 3.5-mile stretch of Route 59 being improved from Ferry Road to Aurora Avenue/New York Street along the Naperville/Aurora border.

Drivers should expect lane closures beginning Tuesday near the Burlington Northern Santa Fe railroad overpass as work to replace a stormwater pumping station continues. The outside southbound lane will be closed just south of North Aurora Road for an estimated two weeks, and the closure is expected to cause long delays.

Naperville city officials on Friday said work largely is complete on the replacement of a large, underground drainage pipe near LaSalle Avenue that caused lane closures and delays.

But removal of medians throughout the roadwork zone continues.

The project, expected to be complete by fall 2015, will widen Route 59 to three lanes in each direction, improve traffic signal coordination and create extra left-turn lanes at four major intersections: 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.
