A container or vessel specifically designed for bridge construction, maintenance, or perhaps containing materials used in bridgemaking.
From 'bridge' + 'pot' (Old English 'pott', possibly from Latin 'potus'). This compound is relatively rare and may be archaic or specialized terminology from bridge construction trades.
This wonderfully obscure word hints at how specialized trades develop their own vocabulary—a 'bridgepot' might have contained pitch, tar, or cement used in bridge repairs, making it a tool specific enough to earn its own name.
