Abstract A highway divider including a plurality of butt-joined divider members which each has two side walls which are oppositely concavely curved in vertical cross-section. The side walls are uniformly curved over the entire height thereof. The divider members are stiffened by at least two spaced-apart transverse webs. The longitudinal edges of the side walls end tangentially in a common horizontal plane. The upper longitudinal edges of the side walls are connected to an underside of a connecting pipe which has a plug at one end thereof and plug socket on the other end.
