People against a further increase in Humber Bridge tolls can have their say at a public inquiry on Tuesday.
The charge for cars is likely to rise by 20p to £2.70 in April and buses will also see a 90p increase.
The Humber Bridge Board is holding the inquiry on the bridge to allow objectors to voice their concerns.
However, many haulage firms and bus companies say they already feel the charge is too high.
More than six million vehicles cross the bridge every year, bringing in approximately £18m.
The Humber Bridge Board pays out £15m every year in repayments and it is estimated the construction loan will be paid off in 2032.
