E-ZPass motorists can pay tolls at higher speeds on their way to Pennsylvania's Pocono Mountains and Lehigh Valley.
The I-80 bridge carried an average of 53,900 vehicles per day last year. There were an average of 56,100 vehicles a day last year on the I-78 span.
Western New Jersey and eastern Pennsylvania are among the fastest-growing areas in the region. Traffic at the toll plazas can come to a standstill in the summer.
The express lanes are expected to be in place by Memorial Day next year.
