At a contraflow system on a motorway, you would typically expect to find the following:

• Traffic directed to flow in the opposite direction to normal on one side of the motorway, usually because one carriageway is closed due to roadworks, repairs, or an accident

• The central reservation physically separated by barriers or cones to create lanes for traffic traveling in the opposite direction on the other side of the motorway

• Temporary lane markings and traffic cones acting as lane dividers, with narrower lanes than usual to accommodate the contraflow setup

• Reduced speed limits clearly indicated by yellow contraflow road signs, designed to keep traffic moving safely through the altered lane configuration

• Clear signage instructing drivers to stay in their lanes and warning of the contraflow system ahead, often including the maximum speed limit applicable during the contraflow

• Possible presence of traffic management personnel, CCTV, or sensors monitoring the contraflow to ensure smooth and safe traffic flow

• Temporary barriers or road markings that separate opposing flows of traffic to prevent collisions

Overall, a contraflow system on a motorway is a temporary traffic management arrangement that reroutes traffic onto the opposite carriageway to maintain movement during lane closures, with safety measures such as barriers, cones, reduced speeds, and clear signage to guide drivers through the changed traffic pattern
