An elevated guideway performing the function of supporting, guiding and propelling pneumatic transport vehicles for passengers and loads. The two-part elevated guideway is formed by two components, each corresponding to one side of the cross section, divided by a vertical axis passing through the center of the slot. Components are not symmetrical, the left hand component having a wider top table. Components are joined through a niche already present at the lower slabs which is filled with a structural resin. Niche for joining the two-part elevated guideway has a central type female-female fitting. The elevated guideway includes guideway guards, two additions for installing the propulsion duct slot seal, tubes for the electric power supply and telecommunication and control cables, the protective railing for protection in the side emergency gangway, the unit for securing the rail via the web thereof, rails and the third and fourth electric power supply rails of the vehicle. The two-part elevated guideway may have, combined on the same beam of the propulsion duct, a secondary propulsion duct, thereby forming a single, non-separable structure.

A variably dimensionable bridge (10) comprising pre-engineered components provided in a kit. The pre-engineered components are constructed of fiber reinforced polymer (FRP) composite material and include at least one floor module (14) for providing a floor; at least two girders (12) for providing opposing substantial vertical sides; and at least two cross beams (16) to lend support to the girders (12). A is a method for constructing a bridge (10) of variable dimensions comprising the use of pre-engineered components provided in a flat-pack kit.

A girder bridge structure with a tall and narrow central-wall-beam that separates two lanes of opposite traffic, lower parapets on each side of the bridge, open bridge decks with optional heated strips, self-driving reference guides, and electric live rails for maximizing the structural efficiency of the strength-mass and stiffness-mass ratios with the tall and narrow central-wall-beam; making the girder bridge lighter; increasing wind-resistance; providing a safer ride to vehicles; lowering the deck height of the bridge; providing reliable self-driving; reducing interference to traffic at ground level; reducing maintenance; improving the aesthetic look of the structure.

A prefabricated, modular bridge is provided that can be assembled to construct bridges of various lengths, widths and skew angles relative to the orientation of foundation elements. The modular bridge includes longitudinal frame members, and a roadway surface made of roadway deck panels and transverse hubs. The transverse hubs define transverse ledges to support ends of the roadway deck panels. The transverse hubs have attached hub attachment clamps that move transversely relative to the transverse hubs to selectively disengage or engage the top flanges of the longitudinal frame members. An assembly for splicing the longitudinal frame members is provided, including an anchor bolt extending between bearing support members attached to the longitudinal frame members. An external reinforcing assembly for the modular bridge is also provided. The external reinforcing assembly includes longitudinal tendons, anchor blocks, and spacers and hangers for deviating the tendons from the bottom flange of the frame members.

A curved pathway including a double helix form with no center support column includes a plurality of segments, wherein each of the segments is formed from a plurality of rods coupled to a plurality of connecting nodes. The plurality of rods are arranged in a skewed tetrahedral geometry, which causes the plurality of stair segments to form a helical structure when the plurality of segments are coupled together. The plurality of rods form a spine on an underside of the plurality of stair segments. A pathway surface is coupled to each of the segments. In alternate embodiments, the curved pathway may be formed from sheet metal creased to form a plurality of linear support locations and connecting nodes.
