J. Barry Stout (November 7, 1936 – October 29, 2016) was a Democratic politician and former member of the Pennsylvania State Senate who represented the 46th District after winning a special election in May 1977. He represented his district from June 7, 1977, through 2010.
Previously he was a member of the Pennsylvania House of Representatives from 1970 through 1976.
On October 22, 2004 PennDOT dedicated the "J. Barry Stout Park and Ride" off the "Beau Street" exit of I-70 in South Strabane Township.[4] [5] Constructed by Greensburg-based Donegal Construction at a cost of $1.2 million, the lighted park and ride lot has 211 spaces and 7 handicapped-accessible spaces. Stout initially suggested the location of the park and ride lot after learning that PennDOT owned the land, which is ideally situated near I-70, I-79, and Route 19.
Stout has credited former Lieutenant Governor of Pennsylvania Ernie Kline with facilitating his election to the Pennsylvania State Senate in 1977.[6]
Stout died at the age of seventy-nine on October 29, 2016.[7]
