This what was posted on the Swan Dolphin website while back:
As Disney Skyliner construction continues near International Gateway at Epcot in the coming months, International Gateway will remain open to Guests traveling along the connected pedestrian walkway.
During construction, Friendship Boat service will remain available to the resort hotels around Crescent Lake as well as Disney's Hollywood Studios. While Friendship Boat service to Epcot is expected to be unavailable from late November until mid-December, Guests will be able to use bus service or the walkway to access Epcot.
