NEW CASTLE — On Monday, Delaware River & Bay Authority officials reported a record traffic volume for the month of June at the Delaware Memorial Bridge.

For the month, the bridge handled 1,627,547 vehicles, eclipsing the previous all-time record of 1,619,637 vehicles set in June 2019. The strength in commercial vehicles and passenger cars offset continued weakness in daily commuter numbers for the month.

DRBA Executive Director Thomas J. Cook said that the bistate agency had modeled a 10% decline in 2021 traffic compared to 2019 figures, which was a record year for traffic on the Delaware Memorial Bridge. During the first six months of 2021, bridge traffic has been slowly recovering, he said.

In 2020, Delaware Memorial Bridge traffic numbers were dramatically impacted due to the COVID-19 pandemic, the DRBA said. In March 2020, traffic volume plummeted more than 350,000 vehicles, with most of the decline during the last two weeks of that month.

Bridge transactions fell to 559,435 in April 2020, a decline of nearly 66%. May 2020 numbers declined by 50%, totaling 875,000 transactions for the month. Traffic numbers stabilized during the summer months but remained down by more than 20% compared to the previous year.

For 2020, the bridge handled 14,124,440 vehicles through the southbound toll plaza, a drop of nearly 23% compared to the 2019 figure of 18,288,314. Revenue at the Delaware Memorial Bridge was off more than $16 million in 2020.
