In November 1962, ground was broken for the first parimutuel horse-racing track in Western Pennsylvania, to be operated by the Washington Trotting Association.

Miller's imprint still exists on the track today, with The Meadows most prestigious race bearing his name (the Delvin Miller Adios Pace for the Orchids), and a statue of his famous sire Adios located at the track's entrance.

In conjunction, the MRN telecast each day's live races and was distributed to local cable providers.

The telecast also included a half-hour preview show hosted by track announcer Roger Huston.

Pittsburgh lawyer Stuart A. Williams purchased the track in 1986, and subsequently sold it to England-based Ladbroke Group PLC in 1988.

[5] The price was reduced to $440 million after GLPI filed a lawsuit accusing Cannery of misleading them about the property's financial performance.

[10][11] Legislation passed in Pennsylvania in July 2004 included The Meadows among the locations slated to obtain a gambling license for slot machines.

[15] Plans called for initial construction of a temporary casino adjacent to the track, which opened on June 11, 2007.

[16] On September 5, 2007, a ceremony was held to mark the beginning of the grandstand removal, which was necessary to clear space for the permanent casino.

The test runs were successful, and at 6 AM on July 8, 2010, the table games (including roulette, blackjack, craps, etc.)

On October 2, 2019, the Pennsylvania Gaming Control Board approved a sports-betting license for The Meadows Racetrack and Casino, which will also offer online sports betting in partnership with DraftKings.

[19][21] The Meadows, the harness racing facility in operation since 1963, forms a component part of the racino.

Races are conducted with a maximum of nine starters on the gate; horses in post ten start from the second tier.
