The state Department of Land and Natural Resources is to start work Monday on park improvements at Hapuna Beach on Hawaii island.

Construction beginning Monday includes replacement of the central walkway, pavilion roofing replacement and new barbecue pits.

An irrigation system for the cabins also will be replaced.

The Hawaii Tourism Authority provided $1 million for various park improvements through grants. The National Park Service provided $100,000 in federal funds.

The 61-acre state recreation area includes hiking rails and picnic pavilions.

Work is expected to be completed in August. 

The park is to remain open, but rental cabins are to be closed during work in that section.

The central parkway also will close, requiring visitors to use alternate north or south paths.
