Project Description:

RMTC was responsible for the design of this new 2.7-mile long, six-lane, two-way urban arterial roadway in Kapolei. The North-South Road includes a new H-1 Freeway interchange, six at-grade intersections, a divided highway with a raised median, sidewalks, bicycle path, drainage, lighting and other utilities. The project includes a major drainage system consisting of a regional drainage channel with a 7,000-cubic feet per second capacity and a 110-acre-foot stormwater sediment basin over a 56 acre site. The project is designed to meet FHWA requirements for federal funding obligation.

RMTC’s scope of work included overall coordination and project administration; preparation of aerial topographic maps, boundary maps, parcel maps, control surveys and right-of-way maps; civil design plans, specifications and cost estimates; acquisition of environmental permits; participation in public involvement programs; preparation of a drainage study and erosion control report; and coordination with local, state and federal agencies.
