Claim:
An apparatus comprising: a modular pedestrian tunnel comprising: a first pedestrian tunnel module comprising: a rectangular frame having a perimeter defined by a first side and a second side each having a first length, and a third side and a fourth side each having a second length, a continuous plate fixed to the frame for protecting a pedestrian passing under the first pedestrian tunnel module, a first profiled element extending continuously along the first side of the frame and having a length equal to the first length, a second profiled element extending continuously along the second side of the frame and having a length equal to the first length, the second profiled element having a shape configured to interlock directly with a first profiled element of an adjacent pedestrian tunnel module, a third profiled element extending continuously along the third side of the frame and having a length equal to the second length, a fourth profiled element extending continuously along the fourth side of the frame and having a length equal to the second length, the fourth profiled element having a shape configured to interlock directly with a third profiled element of an adjacent pedestrian tunnel module, and a plurality of supporting legs hinged to the frame, wherein each of the four profiled elements is configured to withstand one or more of a bending moment and a twisting moment generated by a weight of at least the continuous plate, wherein the first profiled element comprises a structure extending along the first side of the frame and having an L-shaped cross-section having a first segment extending outward from the frame and a second segment extending from the first segment in a first direction, and wherein the second profiled element comprises a structure having a third segment extending outward from the frame and a fourth segment extending from the third segment in a second direction opposite the first direction.
