chaussée

surface (of road); carriageway, roadway; causeway; highway. Belgian roads which are named in Dutch as steenweg (e.g. Waversesteenweg) and in Belgian French as chaussée (e.g. Chaussée de Wavre).

From Old French chauciee, chaucie, from Vulgar Latin *calciāta; there is dispute as to whether this is from Latin calx (“lime”) or its homonym, calx (“heel”) (through the verb calciāre (“stamp, tread on”)). Compare English causeway.
