A decision to raise toll prices on the Clifton Suspension Bridge in Bristol is to go to a public inquiry.
The suspension bridge in Bristol is run by an independent charity
The bridge trustees want to raise the crossing charge from 30p to 50p, claiming the extra cash is vital to maintain the historic structure.
Now, after a number of formal objections, the government has announced the decision should go to a public inquiry.
The bridge is run as a charity and receives no government funding.
John McGoldrick, of the National Alliance Against Tolls, has said: "There is no justification for tolls on any road including the Clifton Suspension Bridge.
"In the particular case of the bridge there appear to be large financial reserves, and the existing tolls seem to be adequate to meet essential maintenance costs."
About four million motorists cross the bridge annually. The toll rose by 10p to 30p in 2003.
