Additionally, delays on I-84 in the Danbury and Newtown areas, which had also been reported earlier, were cleared. This improvement allowed for smoother travel on that particular interstate. Commuters were advised to check traffic updates regularly for the latest information.
Factors Contributing to Traffic
Several factors can contribute to such widespread traffic delays. These often include the sheer volume of vehicles during peak hours, minor incidents, or construction work.
