Route 310 (tapochau road) improvements

Project Grant Award Summary

The Federal Highway Administration (FHWA) awarded $477,194.51 to the Commonwealth of the Northern Mariana Islands Department of Public Works on May 16, 2025, under the Highway Planning and Construction program (CFDA 20.205). This Project Grant funds the realignment and reconstruction of Route 310 (Tapochau Road), a 2.1-mile roadway improvement project in the Northern Mariana Islands. Deliverables include complete roadway realignment to optimize right-of-way utilization, grading operations, utility relocation, new pavement construction, drainage system installation, and implementation of safety features including signage, pavement striping, and markers.

The project encompasses all structural and functional components necessary for a full-service roadway reconstruction, including flexible pavement layers, base and subbase construction, embankment development, comprehensive drainage infrastructure, and safety appurtenances. As a territorial transportation agency functioning similarly to a State Department of Transportation, the CNMI Department of Public Works administers this federally-assisted project in accordance with Highway Planning and Construction program requirements, which emphasize infrastructure preservation, safety enhancements, and comprehensive transportation network improvements across U.S. territories.
