A rotational deck which is used for an emergency vehicle return apparatus in a section of a median strip of a road, includes a pair of angle decks configured to be folded up to serve as the median strip in a normal state, and be unfolded down by hydraulic cylinders toward a surface of the road to serve as a vehicle pass in an event of emergency, and a front block part coupled, by a link unit, to a lower portion of each angle deck. The front block part includes a front block having a shape to reduce a shock from a collision, one or more front block frames configured to provide rigidity by supporting a rear surface of the front block, and a bottom frame configured to support the front block and a lower portion of the front block frame.
