CITY OF WARRENVILLE: Traffic Signal Changes on Winfield Road at Warrenville Road
City of Warrenville issued the following announcement on Feb. 6.
On Tuesday, February 5, the DuPage County Division of Transportation modified the traffic signals on Winfield Road at Warrenville Road.
Left turns are now only permitted on a green arrow.
The change stems from the awkward alignment of Winfield Road through the intersection that makes it difficult to see oncoming traffic when attempting to make a left turn.
