Tonight’s roving closure on the H-1 freeway is postponed until Wednesday due to wet weather conditions.

The work is scheduled for the H-1 freeway, in both the eastbound and westbound directions, between the H-1/H-2 merge and the Halawa interchange, from 10 p.m. tonight to 4 a.m. The Department of Transportation said should wet weather occur Wednesday, work will be postponed to the following night.

State transportation department officials say a survey is being conducted by a vehicle mounted with ground-penetrating radar. The survey vehicle must drive over the freeway multiple times at slow speeds to capture data so a design-build team can accurately prepare casts to rehabilitate the asphalt concrete on the H-1 eastbound, from the vicinity of the Waimalu viaduct to Halawa.

Honolulu police officers will accompany the survey crews. Motorists are urged to drive with caution. The work will be performed as weather permits.

The design-build project, awarded to Kiewit Corporation for $63 million, includes pavement rehabilitation and widening of the current 10-foot shoulder to allow for a 24-foot wide eastbound shoulder that can be used for unrestricted vehicular traffic. Construction is scheduled to begin in April 2018.
