Gateway Motorway Reader May Be Overcharging Motorists A toll point on the northbound Gateway Bridge appears to be faulty in one lane. Photo: Glenn Hunt The company managing the Gateway Motorway and Gateway Bridge last night conceded there may be a systematic fault in the Go Via e-tag reader on one lane of the Gateway Bridge. A spokeswoman made the comments on Tuesday in response to Fairfax Radio 4BC breakfast radio announcer Kim Mothershaw describing how his Go Via tag did not beep when he used the far left northbound lane on the Gateway Bridge. He said the problem had occurred periodically in the past six weeks when he crossed the Brisbane River, but only when he used that lane. Mr Mothershaw said after he checked his account he was charged his toll, plus an additional 43 cents for a video checking fee. Many listeners called 4BC after the segment to say their tags also did not work when they used Lane One. "Given that we have been advised that the customer's tag is correctly mounted, we are going to offer to test the customer's tag to check if it is working properly," the Go Via spokeswoman said. We are also looking at whether there are any tolling anomalies on that particular lane and this will take some time. We are not aware of any issues to date. More than 100,000 vehicles cross the Gateway Bridge each day using one of six lanes. Rough figures - based on one-sixth of the traffic using lane one and being charged an additional 43 cents - could mean $7000 being overcharged each day. Drivers are not advised if they are overcharged and have to manually check their account. Go Via is the company that manages tolls on the Gateway and Logan motorways and the Gateway Bridge for Queensland Motorways. Queensland Motorways runs 63 kilometres of tollways in Southeast Queensland. Tags may not read correctly if they are mounted in the wrong position on the car, if the windscreen is metallic or if the tag is old. Fairfax Media understands that refunds for overcharging can only be claimed in the same month that the incident occurs.
