[3] Evans City is located in southwestern Butler County at 40°46′10″N 80°3′41″W / 40.76944°N 80.06139°W / 40.76944; -80.06139 (40.769310, −80.061409),[4] in the valley of Breakneck Creek.

According to the United States Census Bureau, Evans City has a total area of 0.81 square miles (2.1 km2), all land.

The site that is now Evans City was for a long time a favorite camping ground for Native Americans, who named the creek that ran through it Big Beaver Run, while the French knew it as Casse-cou-anse or "Breakneck Creek", a name adopted by travelers between Fort Duquesne and Fort Machault, and by the English-speaking pioneers of the original township of Connoquenessing.

In October 1878, the railroad was completed to Evans City; the first freight to be delivered was a new boiler to replace one which had exploded in the Sutton flouring mill.

The residence for the pastor of the German Lutheran church, the Henry Young store and other houses were completed, and the new railroad town showed increased signs of business activity.

A council appears to have had control of the place at that time, as mention is made of street improvements and of the appointment of Z. T. Weise as chief of police.

Spanning the Breakneck Creek on iron beams for support, the picturesque railway station was an iconic landmark of breathtaking architecture.

Due to its age and growing structural instability, and against much popular protest, the station was finally demolished in the early 1980s rather than restored.

Services were held in the frame school-building in the old United Presbyterian cemetery, until about 1842, when a brick house of worship was erected.

This is a frame house 45 by 60 feet (14 by 18 m), well furnished, with pastor's study, standing on the old church lot on Main Street.
