The invention provides near-edge protective design for bridge and road construction and a construction method thereof. The problem that safety and caution are poor in existing near-edge protective design especially home protection is mainly solved. The near-edge protective design comprises a protection support and supporting corners. The protection support is composed of a hinge ball and a plurality of adjusting rods. Each adjusting rod comprises a telescopic rod, a fixed rod and a locking device. Supporting legs are arranged at the bottom ends of the fixed rods. Pins are vertically fixed at the bottoms of the supporting legs. The supporting corners are installed on the lower sides of the supporting legs. Four independent protections are designed, through the cooperation of pin holes and the pins, the lateral displacement of the whole support can be effectively prevented, the safety performance is greatly improved, construction is simple and convenient, and the support can be conveniently assembled and disassembled and repeatedly used; the near-edge protective design has high safety and practical value and is wide in application range and high in economic value, and the construction safety accidents can be effectively avoided.
