A partial road closure of a stretch of Route 41 in Gurnee went into effect Wednesday, a week after it was delayed, as crews work to repair a bridge damaged by a truck.

The Gurnee Police Department said the closure went into effect around 9 a.m. Wednesday.

The northbound and southbound lanes of Route 41 have been reduced to one lane in both directions from Kilbourne Road to Depot Road.

Traffic has been redirected using barricades and signs as crews work to repair the railroad bridge near Route 41 and Kilbourne Road.

A semi-truck struck the bridge last Wednesday and caused significant damage to it.

The lanes are tentatively scheduled to reopen by Friday evening.

Police said motorists are urged to use caution if traveling through the area and consider finding alternate routes to avoid delays.

Traffic congestion delays are expected during repair hours.

Officials initially said a larger road closure involving the southbound lanes of Route 41 from Route 21 to Grand Avenue would go into effect last Thursday morning.

That closure was not needed as crews were able to evaluate the bridge without a shutdown being needed.

The evaluation confirmed repairs would be needed to the bridge.
