However, in 1895, Arthur Stilwell founded Port Arthur, and the town quickly grew, being incorporated as a city in 1898. It soon developed into a seaport and, eventually, became the center of a large oil-refinery network. The Rainbow Bridge across the Neches River connects Port Arthur to Bridge City.
