On January 28, 1820, Town was granted a patent for a wooden lattice truss bridge, which became known as the Town Bridge. The design was of great importance because it could be built quickly by relatively unskilled workers from readily available material. The design also avoided the need for the heavy piers needed for stone arches. The design was widely known throughout the world and made Town wealthy (Town is said to have charged one to two dollars per foot in royalties for his designs). Town's design can still be seen in two of Connecticut's remaining covered bridges, Bull's Bridge in Kent and West Cornwall Covered Bridge in Cornwall and Sharon, and in the Eagleville Bridge and the Shushan Bridge in Washington County, New York. Many other extant covered bridges also employ Town's basic design. The lattice is sometimes called a truss, although it lacks vertical members.
