The Washington Redskins have completed the project that has added standing room-only viewing areas to FedEx Field, and on Tuesday told season ticket holders and others on the season ticket waiting list that tickets for those areas are now available.

In an email sent to fans, the team announced that it has sold out all general admission lower and upper deck tickets, and that “party deck” tickets can be purchased for $290 apiece for the season.

Redskins officials have sought ways to improve fans’ game day experience, and one of their goals included making attending games more affordable. The price puts the cost of an upper-level standing room ticket for eight regular season games and two preseason contests at $29 per game.

The Redskins ripped out about 8,000 seats from end zone areas of both upper decks in 2011, reducing FedEx Field’s capacity to about 83,000. In March, the team received approval from the Prince George’s County Department of Environmental Resources to remove another 4,000 seats to complete a round of upgrades that included the installation of the upper level standing decks.

Last summer, the Redskins announced plans to install party decks at FedEx Field, but at the time, had not finalized plans while they investigated whether platform structures that large could be installed in the upper levels of the stadium. The team wound up installing 42-inch deep decks on the three upper levels of the end zone areas.

It wasn’t immediately clear exactly how many standing room only tickets the team has up for sale, but a person with knowledge of the details estimated that the party decks will hold a combined total of between 4,000 and 5,000 people.

That would put FedEx Field’s capacity at about 83,000 again. The Redskins last season had an average attendance of 76,921 people – fourth-highest in the NFL, according to league figures.

A Redskins spokesman declined comment Tuesday morning, but General Manager Bruce Allen said in April that the team was committed to continuing the improvement of FedEx Field, and the team’s Ashburn-based headquarters.

The Redskinsreached an agreement early this month with the state of Virginia that will kick off a $30 million renovation project at Redskins Park

The stadium renovations include the standing room viewing decks, the addition of more suites, new furniture on the club levels, and state of the art ribbon boards to complement the existing HD video boards.
