I'm a driver but absolutely believe that all arterial routes should have proper segregated cycle lanes, and if that means losing a lane in a dual carriageway then good.
It's not a dual carriageway.
For what it's worth, I'm a cyclist and driver, and definitely think they need to do something similar on all major roads, was a good idea that some useless cretin at the council has got their teeth into and completely fucked it up, it looks horrendous.
I'm convinced Bablake have had a say in this, convent how it goes from the school to the playing fields but coundon court and hollyfast aren't included.
