KAILUA-KONA, Hawaii (AP) - Hawaii transportation crews are installing no parking signs and moving in concrete barriers to prevent cars from stopping along a Big Island highway to see a lava tube.
West Hawaii Today reports the Huehue lava tube on the side of the Queen Kaahumanu Highway about 2 miles (3.2 kilometers) north of the Kona airport has become an increasingly popular tourist destination.
Kona-area residents driving on the road have reported unsafe conditions and near misses as visitors cross the highway and stopped cars pull onto the road.
State Department of Transportation spokeswoman Shelly Kunishige says crews started installing the signs on both sides of the highway earlier this month, and they will be placing barriers in coming weeks.
A no-trespassing sign will also be posted at the lava tube's entrance.
