 Continuing south, the road passes over the M2 and High Speed 1 on Sundridge Hill where those two routes reach land again after crossing their respective Medway bridges.Proceeding down Sundridge Hill, the road descends from the Downs and enters the Medway Gap at Cuxton, where it then becomes the Rochester Road and later Formby Road as it makes its way to Halling.At Halling, the A228 departs from the old route that took it through the village and proceeds along the Halling Bypass which then links up with the Snodland Bypass near Holborough.
