causeway

From Middle English cawcewey, with the first element from Middle English cauce, from Anglo-Norman, Old Northern French caucee or Old French caucie, cauchie (“route, highway”), from Vulgar Latin *calciāta (compare modern French chaussée from Old French chaucie, itself from the same source), either from Latin calx, calcis (“limestone”), or alternatively from Latin calciō (“to stamp with the heels, tread”), from calx (“heel”). The second element corresponds to English way.
