Ramp construction is scheduled to begin Monday at the Randall Road interchange on the Jane Addams Memorial Tollway in northwest suburban Elgin.

Weather permitting, ramp construction will begin Monday at all four I-90 interchange ramps, according to a statement from the Illinois Tollway. Electronic message signs will be in place to alert motorists of dates and times in which lanes will close.

Construction will begin by shifting traffic on the ramps to the left, so that work can be done on the right, the tollway said. Traffic will then be shifted to the right, so that work can be done on the left side of each ramp.

Lanes will also close on Randall Road next to the interchange ramps, “to provide a safe construction work zone for drivers and workers,” the tollway said. Northbound Randall Road lanes will close first for median pavement repairs, the tollway said. When those repairs are completed, the right lane on southbound Randall Road will close.

The construction, which is scheduled to be completed this fall, includes repairs and shoulder reconstruction on portions of the ramps and on the medians on Randall Road, the tollway said.
