Crater Road (Rt. 378) and Haleakala National Park’s summit road will close to visitor traffic from Wednesday evening through Thursday afternoon while a slow-moving convoy transports extremely wide loads to the Daniel K. Inouye Solar Telescope near the volcano’s summit.
The roads will be closed to visitors from 6 p.m. Wednesday, Aug. 19, through 2 p.m. Thursday, Aug. 20. The summit will not be accessible for sunrise viewing on Thursday. Although the park road to the summit will reopen at 2 p.m. Thursday, the visitor center will remain closed all day.
The headquarters’ visitor center at 7,000 feet of elevation will also remain closed all day for bookstore inventory.
Back country permits will be available in the foyer of the headquarters’ visitor center from 2-4:30 p.m. Thursday. Backpackers planning to hike into the crater on Thursday are strongly urged to obtain their permits a day in advance.
Visitors who pay an entrance fee on Tuesday, Wednesday, or Thursday (Aug. 18, 19, 20) will have a one-day extension on the usual three-day pass. The extension will apply to both the Kipahulu and Summit Districts.
The Advanced Technology Solar Telescope Project is located outside of park boundaries. The convoy’s travel through the park is being allowed via Special Use Permit. The convoy will travel at 2 to 5 mph and transport equipment that is over 23 feet wide. The road precautions are in place due to the size of the convoy and narrowness of the roads.
The convoy will include three semi-truck trailers and various support vehicles.
