Murrysville is a home rule municipality in Westmoreland County, Pennsylvania, United States.

[4] The well was drilled in 1878, and until a gas pipe line was attached to the well in 1883, approximately 35 million cubic feet of gas a day was released into the atmosphere, resulting in a total of about 60 billion cubic feet of natural gas released into the atmosphere from this single site[5] Murrysville was described in the first half of the 20th century as being "the center of a district dotted with gas wells, the first of which was bored in 1878; wild speculation in leases precipitated the open conflict known as the 'Haymaker Riots,' named for the speculator killed in one of them.

The trees were landscaped to grow and form the letters by local Boy Scouts.

The sign is situated on a large hill as one enters the Municipality from the Murrysville–Monroeville border, near U.S. Route 22.

In 1977, Murrysville was designated the "Gateway to Westmoreland County" by Mayor Walt Dollman in conjunction with the Chamber of Commerce.

In 2012, community leaders upgraded sign and landscaping elaborately at the main entrance at the Allegheny / Westmoreland border featuring this designation.

As is shown at the introduction of this page, the Gateway designation is featured on the official Seal of the Municipality.

Murrysville surrounds, but does not include, the Borough of Export, which is a separate municipal entity.

[16] On Dec. 18, 2023, the Municipal Authority of Westmoreland County issued a mandatory water conservation order for Murrysville and others, including energy companies using water from the Beaver Run Reservoir for fracking, due to an ongoing drought.

Those changes are likely to include more extreme and intense rainfall — something scientists already have reported noticing — and increased drier weather in between and drought, along with higher temperatures.

[18] “In general, we expect worse drought over most of the U.S. as a result of human-caused warming, and Western Pennsylvania is no exception,” said Michael Mann, a professor and director of the Penn Center for Science, Sustainability and the Media at the University of Pennsylvania and author of “Our Fragile Moment.” [19] Murrysville is part of the Franklin Regional School District.
