The utility model relates to the field of crossroads, and discloses a guardrail-free type single-opening crossroad which comprises a crossroad mechanism, a limiting mechanism and a driving mechanism, and the crossroad mechanism comprises a first rail, a second rail, a third rail and a fourth rail; the driving mechanism is used for driving the third rail and the fourth rail to conduct linear displacement. The limiting mechanism comprises a first-stage limiting mechanism and a second-stage limiting mechanism, the first-stage limiting mechanism is used for carrying out auxiliary displacement limiting on the third rail and the fourth rail, and the second-stage limiting mechanism is used for carrying out bending limiting on the third rail and the fourth rail. Through the cooperation of the first-stage limiting mechanism and the second-stage limiting mechanism, the linear displacement thrust of the third rail and the fourth rail can be increased, the bending force of the third rail and the fourth rail is reduced, a
