Yeah they did close *most of it* not all of it though.
After asking my dad the specifics of the hike he told me it was called the Carbon River hike and that there is a big bridge over the river heres a pic of it.

November 2006 Flooding
Heavy rains caused flooding that damaged park roads and facilities.
State Routes 410 & 123 and the Paul Peak/Mowich Lake areas are closed at the park boundaries by winter conditions
but remain open to normal, non-motorized winter activities such as hiking, snow shoeing and cross-country skiing.
Walk-in access is available to Carbon River area trailheads by parking at the entrance and hiking the designated rough route along the washed out road.Repair efforts are currently focused on the Nisqually Entrance to Longmire corridor. The road crew is reconstructing the 200 yards of missing road at Sunshine Point. Restoration of utilities at Longmire is also underway.
And were leaving Friday the 8th!
