The Lanikai Pillbox Trail will be closed for two months beginning June 21, the Dept. of Land and Natural Resources said today.

During the closure, crews will rehabilitate two historic World War II-era structures on the popular hiking trail on Kaiwa ridge in Kailua.

The project was originally planned for March but was delayed pending FAA approval of the contractor’s flight plan to fly up materials and equipment.

Work will consist of concrete spall repair and replacement of rusted steel roof supports. New steel flange roof supports will be installed as well as roof sealant to the pillbox structures to prevent weathering.

The project contractor is Tokunaga Masonry, Inc. and the project will cost the state $248,228 to complete.
