Roadside fiber is a game-changer for transportation authorities, road users, and for the communities located along America's highways and railroads. Dura-Line creates the physical pathways that enable safer, more efficient travel across all modes, as well as the middle mile links that extend connectivity to remote and underserved locations.
Applications
Roads are central for us, but we offer solutions that fit any transportation application, in any environment:
- Underground roadside networks
- Rail and tunnels
- Metro
- Light rail
Fueling the growth of cutting-edge ITS systems around the nation and across the globe.
We’ve worked with state transportation authorities around the country to install pathways that allow them to build or upgrade ITS and roadside fiber networks. These networks not only improve travel and create much-needed middle mile connectivity, spare capacity along routes can also be used in lucrative leasing agreements with partners in the private sector.

DOT Success Stories
ADOT needed to overcome numerous challenges to meet their goal of delivering high-speed internet to Arizona's middle mile communities across 400 miles of conduit and fiber: rocky terrain, protected species and culturally sensitive grounds, rockfall areas, and rodent hazards -- all while minimizing disruption to road users. They chose to use horizontal directional drilling, plowing, and MicroTrenching to install FuturePath Armored 7-way along roadways as well as on existing tunnels and bridges, and routed it through an innovative triple vault to separate ADOT infrastructure from commercial partners’. These choices helped them meet their technical and commercial goals as well as saved on construction costs, and because of Armored FuturePath's robust design, ADOT’s thoughtful planning will go a long way in preventing accidental cable strikes and allowing space for future expansion and leasing.
The PA Turnpike Commission (PTC) wanted to upgrade their communications systems to a fully modernized integrated transportation system (ITS), and provide essential middle mile connectivity to Pennsylvania's underserved communities. Installing safely at night along 500 miles of busy roadside would be challenging, but Microtechnology -- in this case, MicroTrenching FuturePath 8-way and then placing a 288F HD micro cable -- provided the necessary flexibility, speed, and small footprint. Now, PTC retains 4 pathways for their own use with four spare pathways for leasing to commercial providers who will establish lateral connections to remote communities.
NCDOT's challenge was to build out an ITS while expanding existing fiber for universal access, while enabling opportunities for commercialization, all along a 600-mile route that includes one of our nation's most dangerous highways. By installing three standard HDPE conduits and subdividing each one of them with three MicroDucts, they tripled the pathways available to both NCDOT and the additional pathways that facilitated expanded connectivity.
Faster, safer, and less expensive installations with MicroTechnology
HDPE conduit provides superior durability and comes in a variety of formats that provide the flexibility to build in any environment, while maintaining good stewardship of public funds.
Dig Once: FuturePath allows you to install the fiber you need for your immediate needs and reserve extra pathways for future upgrades when demand inevitably increases, while a standard HDPE conduit’s space can be maximized with subdivision and OverRides.
Jetting enables streamlined fiber placement: HDPE is naturally suited to air jetting, which makes for faster fiber placement and lower labor requirements.
While HDPE works well with conventional installation methods, innovative methods like MicroTrenching, allow you to lay conduit and place fiber at unprecedented speeds, saving time, money, and space in narrow shoulders.
