Three to four right lanes will be closed on the H-1 Freeway in the eastbound direction between the H-1/H-2 Merge and the Waimalu/Pearlridge offramp (Exit 10), on Tuesday nights through Sunday mornings, nightly. Roadwork will begin with a three-lane closure at 7 p.m., and at 8 p.m. a fourth lane will be closed. See lane closure times below.

HDOT will perform concrete repairs on defected areas that are located with sounding equipment, repair expansion joints, and conduct drain improvements.

Some work in the westbound direction will be needed for testing and rebar welding and HDOT will provide advanced notice of these closures.
