The website spoke to transport expert Prof Stuart Cole, of the University of South Wales who said the traffic increase was more than you would expect, “This is quite a big shift in demand, because the price went down by 16% and we’ve got an increase of 10% to 11%, you would expect demand to increase by 4% to 5% but it’s double that.”

It says some of the additional increase could be the result of temporary factors, such as disruption on the railway between south Wales, Bristol and London and fine weather encouraging more leisure travel this year than last year as well as four Ed Sheeran concerts bringing people to Cardiff in June.

It’s projected traffic could increase by 30% when the tolls are removed completely as people move to cheaper areas and commute using the bridges at no cost.
