Four new marine highway projects, located in North Carolina, Alaska and Puerto Rico, have secured project designation from the US Department of Transportation ’s (DOT) Maritime Administration (MARAD).

The four projects are North Carolina’s Riverbulk Steel Shuttle, the Yakutat freight expansion service and Unalaska Express project in Alaska, and the Puerto Rican maritime transportation services project.

The designation as part of America’s Marine Highway Programme (AMHP) will enable the projects to apply for federal funding to resolve supply chain issues under the Bipartisan Infrastructure Law.

MARAD stated that ‘a marine highway project is a planned service or expansion of an existing service, on a designated marine highway route’.

The project designation will enable Riverbulk Steel Shuttle to maintain the existing barge service, which ships steel plates along the M-95, M-64 and M-495 marine highway corridors.

It will also support the expansion of an existing freight service on the M-5 (AK) marine highway route, which will help the Yakutat freight expansion service serve the city and Borough of Yakutat, Alaska.

MARAD’s project designation will also enable the expansion of the CMA CGM barge terminal that operates in the City of Unalaska’s International Port of Dutch Harbour. The harbour uses the M-5 route to link Kodiak, Seward and Valdez.

Lastly, under the Puerto Rico maritime transportation services project, the designation will allow the creation of routes between the municipality of Ceiba and the islands of Culebra and Vieques.

These routes will help island residents avail vital services from the main island, including food, groceries, furniture, construction services, materials and equipment.

US Transportation Secretary Pete Buttigieg said: “We are using resources from President Biden’s Bipartisan Infrastructure Law to make historic investments in our nation’s marine highways – part of our continuing action to address global supply chain disruptions and lower costs for American families.”

Last month, MARAD announced additional funding of $234.3m for the Port Infrastructure Development Programme (PIDP).
