Harbor Link’s underground conduit system will provide critically needed infrastructure for telecommunications services from Baltimore, Maryland, through Washington, DC, to Northern Virginia. Currently, underground networks in these areas are experiencing significant congestion, preventing companies from rapidly and efficiently installing new fiber. While some of our network is still in the planning and negotiation phases, construction has already begun in key areas.

Maryland – Long Haul

Construction Began: 1Q 2022
Estimated Completion: 1Q 2023

Private businesses, state and local governments, and telecommunications providers need high-speed connections between the region’s urban areas. Harbor Link’s open conduit and dark fiber plan satisfies this need between Baltimore, MD, Washington, DC, and Northern Virginia.

Key highlights of the Maryland Long Haul conduit route include:

  • 60-miles of wholly new conduit
  • Duel, diverse paths along I-95 and MD RT-97
  • 300 easy access points to the conduit system from Maryland through Northern Virginia
  • Full pathway resiliency, diversity, and redundancy
  • End-to-end connectivity under 1 millisecond from Baltimore to Northern Virginia

5G, the next-gen wireless standard, will require massive investment in telecom infrastructure over the next decade. The Harbor Link Long Haul connection provides a solid backbone route for numerous carriers to develop their networks as the 5G era continues to evolve.

Harbor Link is constructing a privately-owned, open-access, telecom conduit system to make it easy to dramatically upgrade and expand connectivity services between Baltimore, MD, Washington, DC, and ultimately, on to Ashburn, VA, the data center hub of the East Coast.

The Maryland Long Haul sections of Harbor Link’s planned network began construction in the 1st quarter of 2022.
