Like many pioneer towns in Western Pennsylvania, West Newton earned its early historical relevance by playing a key role in the westward expansion of the United States. The Simerals were the first family to operate in this area and operated a small ferry on the Youghiogheny River halfway between Connellsville and McKeesport. A New Jersey native and whiskey rebel named Isaac Robb, laid out the town of West Newton, however, it was originally called "Robbstown". The town grew slowly as the community served as a trading outpost where the Old Glades Indian trail met the Youghiogheny River. West Newton's fortunes changed during the mid 19th century. River commerce increased with the construction of slack water dams in the 1830s. The introduction of the Pittsburgh, Connellsvile, and Markles Paper Mill provided early economic developments. Despite facing devastating fires, floods and tragic train wrecks in the 20th century, the people of West Newton persevered, continuing to develop both the infrastructure and economy of their community. As time progressed West Newton eventually transitioned into a bedroom community with a vast majority of residents working outside of the boroughs limits. The community saw new economic life blood, serving as a trail town along the Great Allegheny Passage for visitors around the world.
