The suggested (unbuilt) route to Driffield would use a 70mph one-way slip road, which could be a bit hairy.
The environmental impact assessment is still available online. They acknowledge that cyclist safety is worse at this point than before. They also state that only ONE property (and that owned by the DfT anyway!) was eligible for noise mitigation measures. What they didn't tell locals beforehand is that the road is, unusually for the UK, surfaced in concrete on its way through the entire Cotswold Water Park, and the tyre roar can be heard from China.
