H1 Rehabilitation Middle Street to Vicinity of Ward Avenue

Commuters along H-1 Middle Street to the vicinity of Ward Avenue have endured the busiest traffic in Hawaii with approximately 200,000 vehicles per day. As a part of this ambitious plan, Hawaiian Dredging was awarded the H1 Rehabilitation Project that spanned from the Middle Street vicinity to the Ward Avenue overpass.

Hawaiian Dredging worked around the clock to execute the plan that included the reconfiguration of three 12-foot wide lanes into four 10-foot wide lanes in each direction. The scope of the project also included new highway lighting, restriping of the lanes, upgrading the railings on the Palama Separation Bridge, and the widening of the Nuuanu Stream Bridge in the eastbound direction accommodate the new lane. Also included with the improvements, a host of roadside equipment were also installed and included traffic cameras, a vehicle spot speed detection system, license plate recognition (LPR) system, a new vehicle traffic counting system, and the replacement and upgrade of some of the destination and regulatory signs.
