New alignment (and name - Peninsula Way) of A228 near Hoo missing in Google Maps, but bang up to date in OSM: see http://tools.geofabrik.de/mc/?mt0=mapnik&mt1=googlemap&lat=51.4263&lon=0.54859&zoom=15

Same in TomTom: http://routes.tomtom.com/#/map/?center=51.4263%2C0.54859&zoom=12&map=basic

Bing maps have the new road, but call it Ratcliffe Highway (which is actually the name of the remaining portions of the old road, now a minor road): http://www.bing.com/maps/?v=2&cp=51.43160359990295~0.5541890554995277&lvl=13.999999999999998&dir=0&sty=c&form=LMLTCC
