Commonwealth Of The Northern Mariana Islands Department Of Public Works

The Commonwealth of the Northern Mariana Islands Department of Public Works, a U.S. local government entity headquartered in Garapan, Saipan, functions as a territorial transportation agency recipient of federal highway and infrastructure grants from the Federal Highway Administration, performing road construction, pavement improvement, drainage system installation, and highway administration and training support across the Northern Mariana Islands.

The organization operates as a territorial equivalent of a state Department of Transportation, receiving project grants rather than competing for contracts. The Department of Public Works acts as prime recipient on 107 of 108 recent awards (99% prime footprint), with a single sub-award as a disposal contractor to Environmental Quality Management, Inc. on a modification. All activity is concentrated in federal transportation grants under two CFDA programs: the Highway Planning and Construction program (CFDA 20.205) accounts for the vast majority of awards, and the Territorial and Puerto Rico Highway Program (CFDA 20.298) funds territory-specific improvements. A single discretionary grant under the National Infrastructure Investments program (CFDA 20.933) provided $12.07 million for Route 310 (Tapochau Road) realignment and reconstruction.

The Department of Public Works receives nearly all its federal funding from a single customer: the Federal Highway Administration, which issued 106 of 108 awards in the source data. The remaining two awards came from the Environmental Protection Agency Region 9 (one award) and the Department of Transportation's Immediate Office of the Secretary (the $12.07 million RAISE grant). Combined obligated dollars across all awards total $78.6 million. Recent work includes three overlapping tranches of Route 35 (Airport Road) improvements on Saipan totaling $2.23 million (awarded August 2026 under Territorial and Puerto Rico Highway Program), Route 36 (Windward/Chalan Kalabera) phases spanning approximately 3.7 miles with multiple awards in the Highway Planning and Construction program, Route 310 (Tapochau Road) realignment and reconstruction across multiple awards totaling over $5 million in planning, construction management, and construction phases, Route 10 Phase 2 hazard elimination and overlay work on Rota ($4 million awarded August 2025), and recurring highway administration, technology transfer, and training support activities funded under annual stewardship agreements with FHWA.

Activity has grown from ten awards in 2022 to a peak of 23 in 2024, with 18 awards in 2025 and five in the first eight months of 2026. Fourteen awards with ultimate completion dates within the next twenty-four months face recompete or renewal, including ongoing Route 310 reconstruction (completion January 2027) and Route 35 improvements (completion December 2027). The organization's grant portfolio spans Saipan, Tinian, and Rota islands, with all performance conducted within the Northern Mariana Islands and all administrative oversight maintained by the Department of Public Works under federal stewardship requirements.
