Drivers using the Severn bridges face an inflation-busting toll rise of 3.3%, the Government said.
Cars travelling from England to Wales on the M4 and M48 crossings will be charged £6.20 from January 1 - up from £6 this year.
Transport minister Stephen Hammond said the cost for vans and minibuses travelling west would rise from £12.10 to £12.40 (2.5%), and from £18.10 to £18.60 (2.8%) for lorries and coaches.
He said: "The toll levels will be confirmed in an order made by the Secretary of State in December."
The latest annual price hikes were revealed following a written Commons question from Labour MP Jessica Morden.
Motorists pay only to enter Wales. Driving into England is free, with no toll booths on the eastbound carriageways.
