Tolls on the Humber Bridge will not increase for at least another 18 months after the government awarded a £6m grant to its operator.
Transport minister Sadiq Khan says the money will allow the Humber Bridge Board to install a dehumidification system that will prevent corrosion on the bridge's suspension cables.
Charges to use the bridge have already been frozen for the past three years, with two-,three-, and four-axle HGVs paying £10.90, £14.60 and £18.30 respectively.
The extra funds will also allow the board to continue to meet repayments on the bridge's £330m debt, without authorisation from the local authorities.
Meanwhile, Ian Gallagher, Freight Transport Association policy manager for Wales, says his members want the government to provide more financial support for the Severn Crossing.
He adds: "Many companies operating across the Anglo-Welsh border are racking up tens-of-thousands of pounds in tolls each year. The recession is not discriminating by region, and neither should the government."
All HGVs currently pay £16.30 to cross the Severn.
