Fans are asked to be in their seats by 6:30 p.m. ET for the 7:10 p.m. games on Friday and Saturday, and by 2 p.m. on Sunday for the 3:05 regular-season finale.
The Red Sox urged their fans in a news release to arrive early and take public transportation to Fenway Park for all three games.
The ballpark gates will open two hours prior to each game, which is a half hour earlier than usual.
Fans can take the MBTA's Green Line to Kenmore Square, and also the commuter rail to Yawkey Station, which is just 511 feet from the entrance to Fenway Park. Yawkey Station is part of the commuter rail's Framingham/Worcester line, which runs from Worcester to South Station.
