the "bybus" goes around the town and to the communes of saint-martin-des-entrées and saint-vigor-le-grand. there is one main line ("chojnice / st-martin-des-entrées") and three minor one's toward the different districts. the "bus verts" invented by the "conseil général" is a way to get to the surrounding communes (lines 30, 70, 71, 72, 73, 74). 3000 parking spaces in the town center make it an easy place to park. furthermore, most car parks are free. the "by-pass" is bayeux's ring road. the first part was built after the battle of normandy by british soldiers. the roads in the town center were too narrow for the tanks to get through. the "by-pass" used to be the "route nationale 13" until a motorway was built (a13 autoroute).
