The tolls were reduced for all vehicles back in April 2012, with car tolls dropping from £3 to £1.50 per crossing.
Since then traffic across the bridge has risen by an average of 29%, with car and truck usage rising by 31.1% and 33.6% respectively.
Sean Chaytor, chairman of the Humber Bridge board, said: “Having low tolls has had a significant impact on both the region and on individual users.
“More and more businesses now operate on both sides of the estuary and more workers than ever are commuting across the water to work.
“The north and south banks of the Humber have never been more connected – and we remain committed to ensuring this trend continues.”
He added: “With affordable tolls and reduced journey times, the proposition of living on one side of the estuary and working on the other has never been stronger – meaning people looking for work now have a far greater choice and companies looking to recruit have a far greater pool of talent to draw from.”
Chairman of the Hull & Humber Chamber of Commerce’s shipping and transport committee, Graham Cross, told BQ: “The Humber economy is at a pivotal point in its development with the oil and gas, ports and food processing industries continuing to contribute significantly to the region.
“Investment from Siemens’ on the north bank, Dong Energy and Able Marine on the south bank along with other investments, also endorse the significance of this regions contribution to the UK’s energy requirements.
“The Humber Bridge is the vital link that draws both banks of the river together and the continued commitment to low tolls will ensure that the crossing of the river is not a barrier to the regions development.”
Toll charges remain the board’s sole source of income, with every penny spent on running costs, maintenance, and servicing the debt.
