Removed the description of the A299 as being a "motorway-standard" dual carriageway. It does not have hard shoulders and has several at-grade roundabouts, such as with the A28. However, it is still a good quality dual carriageway road.
Changed description of the A2 to be "motorway-standard", as this has four lanes of traffic in each direction plus hard shoulders, of the same quality as the M2.
