5 Most Congested States in the US

4. Delaware 

Vehicles Per Mile: 149.47 

Despite its small size, Delaware grapples with significant traffic infrastructure challenges. Commuters spend 75.29 hours annually in congestion, ranking poorly compared to Connecticut and New Hampshire. High administrative spending is a notable issue, with Delaware spending $148,736 per mile of highway. Although rural arterial pavement condition and bridge rankings are favorable, administrative disbursements and urban congestion present challenges. Delaware has implemented the “Toward Zero Deaths” plan to address these issues.
