Gurnee, IL – Drivers in Lake County are facing delays this afternoon after a key roadway in Gurnee was shut down due to flooding concerns tied to the Des Plaines River.
According to the Gurnee Police Department, all westbound lanes of Grand Avenue (IL-132) at O’Plaine Road were closed as of 2:15 p.m. Saturday, April 18, 2026. Traffic is currently being rerouted to southbound O’Plaine Road while officials continue monitoring rising river levels that could further impact the area.
The closure affects a heavily traveled corridor near Gurnee, just north of the Chicago metro area, and could disrupt weekend traffic patterns for both local residents and commuters passing through Lake County.
Authorities warn that conditions remain fluid. If water levels continue to rise, additional closures—including a full shutdown of Grand Avenue—may be necessary. Police emphasized that safety remains the top priority as crews assess roadway conditions near the river.
Drivers are strongly advised not to bypass barricades or attempt to drive through standing water, which can be deeper and more dangerous than it appears. Law enforcement is actively directing traffic in the area, and motorists should expect delays while detours remain in place.
Officials are urging drivers to plan alternate routes and allow extra travel time throughout the afternoon and evening hours as monitoring continues.
