A representative from the U.S. Department of Transportation (DOT) was in Westport Tuesday explaining to local officials how "congestion pricing" could ease traffic on I-95.

The U.S. DOT is offering a grant for any metropolitan area interested in trying the experimental method of managing congestion. The plan calls for state officials to charge people to use I-95 during the most congested times in certain areas.

A DOT representative says between 5 to 10 percent of the cars need to be removed from the road during congested times to keep the highway free-flowing. Revenue would then be used to invest in transit and other methods to reduce the number of cars.

Concerns include the impact the plan would have on local roads, like Route 1, and the impact to people with lower incomes.
