The walkway from Congress Park to DTD is gone and construction has not yet begun on it's replacement. There is a sidewalk along Buena Vista Dr that is still there.
The walkway from the Carriage House area to the West Side is unaffected.
over on another Disney forum someone has posted the following
Hello! Just checked in to ssr and have been told that the congress park walkway to dtd is open again - reopened about a week ago. Haven't seen it on here so thought I'd post to let people know.
Off to bed now - AK and MK tomorrow
