Millions of toll payments for crossing the new Mersey Gateway Bridge may have to be refunded, a lawyer has said following a legal test case. The Traffic Penalty Tribunal (TPT) found a driver was not liable to pay the £2 toll as Halton Council had not specified the fee correctly. It also failed to give correct notice of charges on the £600m Runcorn to Widnes crossing, the TPT said. Halton Council said it "strongly disputes" both points.
