Work to replace lava tube bridge begins Thursday
Work to replace the deteriorating bridge into Nahuku lava tube in 91Ö±²¥ Volcanoes National Park will start Thursday.
The lava tube will remain open, but the entrance and exit will be on the east (or “exit”) end only.
The rainforest trail, the stairs that lead to the trail, and about 50 feet of the lava tube entrance beyond the bridge will also be closed during the upgrade.
The bridge replacement project should be complete by the end of June, according to HVNP.
Nahuku, also called Thurston Lava Tube, is a one of the most popular features in the park. The lava tube was formed during the ‘Aila‘u eruption from Kilauea volcano about 500 years ago.
Parking is extremely limited at Nahuku, and it is recommended that visitors explore the lava tube before 9 a.m. or after 5 p.m. for the best chance of getting a parking spot.
The lava tube is open 24 hours but is only lit between 8 a.m. and 8 p.m. Flashlights are recommended outside of those hours.
