Structural assemblies for constructing bridges and other structures

A structural assembly comprising:

• a) an elongated member defining an internal space;
• b) a plurality of framing members connected to the elongated member at a plurality of pin connection nodes, each pin connection node comprising a pin interconnecting the elongated member, a first one of the framing members, and a second one of the framing members;
• and
• c) a tamperproof arrangement blocking access to the pin.

A bridge comprising:

• a) a first chord;
• b) a second chord;
• c) a plurality of web members connected to the first chord at a first plurality of nodes and to the second chord at a second plurality of nodes, each node of the first plurality of nodes being a pin connection node, the pin connection node comprising a pin interconnecting the first chord, a first one of the web members, and a second one of the web members;
• and
• d) a tamperproof arrangement blocking access to the pin.

A structural assembly comprising:

• a) an elongated member defining an internal space;
• b) a plurality of framing members connected to the elongated member at a plurality of nodes;
• and
• c) a support for supporting an illumination system, the illumination system comprising a lighting device for emitting light from the elongated member, at least part of the lighting device being located in the internal space when the support supports the illumination system.
