Metro Mayor Steve Rotherham has announced plans to cut the price of the fast tag toll to just £1 for all residents within the Liverpool City Region.
If approved, the 20p reduction will come into effect in April and could save drivers who use the tunnels daily up to £400 a year.
Drivers wanting to benefit from the cut in price will have to register for a personal use Mersey Tunnels Fast Tag.
Under the proposals submitted to the Liverpool City Region Combined Authority Transport Committee, the cash toll for cars will be frozen at £1.80, still 20p less per journey than the rise authorised by the Tunnels Act
The tolls for all other vehicles – including large vans, coaches and HGVs – will also be held at 2018 rates.
Metro Mayor Steve Rotheram said: “I’m pleased today to be able to submit a proposal for a new £1 Fast Tag toll, delivering on the commitment I made during my election.
“If approved, this will be the lowest tunnel toll in over 25 years, with the rate available to the people of the Liverpool City Region 24 hours a day, seven days a week, every day of the year.
“Nobody likes to have to pay to use the tunnels, but they are a critical element of the city region’s infrastructure and we do not receive any central government funding to effectively operate, maintain and upgrade them.
“During the 2015 general election the then Chancellor promised that we would receive national funding for the tunnels but this has not been forthcoming.
“Until this happens I will continue to work to keep the tolls as low as possible, especially for city region residents.”
