Has anybody else noticed the white line in the middle of Charminster Road is in fact nowhere near the centre of the available space?

If you drive from the town centre along Charminster Road between Hankinson Road and Markham Road you actually have to straddle the line. Only a third of the width is on one side while two thirds are on the other.

Can anyone from the highway department tell me why this might be?

Les Lock, Charminster road, Bournemouth
