The H-1 Shoulder Work and PCCP Pavement Rehabilitation will be completed in 3 phases. Due to the success of the first phase of the project, an additional phase was added in late 2018 to further rehabilitate the H-1 Freeway.
Phase 1 was completed in the Fall of 2018.
Phase 2 began in the Fall of 2018 and will end in the Winter of 2019.
Phase 3 was completed in early Summer 2019.
Phase 1 consisted of pavement rehabilitation of approximately 2.0 miles of H-1 East bound and West bound lanes.
Phase 2 is the widening of the shoulder for an additional 1 mile of the H-1 East bound between the Waimalu Viaduct and the Aiea Off Ramp. Highway lighting, drainage systems upgrades and safety upgrades to the highway shoulder will also continue as part of Phase 2.
Phase 3 work included the installation of precast concrete panels in 3 additional areas. Two of these areas are located at the Pearl City Viaduct, both East bound and West bound, while the third rehab location is on the H-1 East bound near the Aiea/Stadium off-ramp.
