William Etheridge

William Etheridge (baptised 3 January 1708[1] – 3 October 1776) was an English civil engineer and architect, best known for his work on several wooden bridges of mathematical design.

[4] From 1744–1749, he worked on the supporting wooden structures during the construction of the Westminster Bridge, first as a foreman and then as the master carpenter.

[2][3][8] In 1747, businessman and plantation owner Samuel Dicker moved from Jamaica to a newly acquired estate in Mount Felix near Walton-on-Thames, Surrey, England.

[2] Despite Dicker's initial projections of 200 years lifetime, a 1778 survey found the bridge to be severely decayed.

Sometime before 1750, Etheridge designed the Old Bridge over River Bann at Coleraine, Northern Ireland.
