To reduce congestion, 10 of the 11 toll plazas on the roadway were converted into one-way plazas between September 2004 and February 2010, dubbed "one-way tolling". Under this program, the toll is doubled in one direction, and the other direction is toll-free. The Cape May (in Upper Township), Great Egg (in Somers Point), New Gretna (in Bass River Township), Barnegat (in Barnegat Township), Asbury Park (in Tinton Falls), Raritan (in Sayreville), Union (in Hillside), Essex (in Bloomfield), Bergen (in Saddle Brook), and Pascack Valley (in Washington Township) toll plazas had been converted to one-way toll plazas. The Toms River Toll Plaza (in Toms River) is the only location on the parkway mainline where a toll is collected in both directions.
