The bus lane was expensive to build.
It takes up more than two lanes but only guides buses in one direction, so buses are still delayed in heavy traffic.
When a bus breaks down it causes more delays.
If we had not been in the EU it would not have been funded, we could have had painted bus lanes on both sides of the road, for the full length of the road, at a fraction of the cost.
(Our poor town planning decisions should not be a reason for leaving the EU.)
