High-Speed Internet for Colorado

Welcome to Colorado, home of a diverse landscape of arid desert, river canyons, mesas, pristine lakes and snow-covered Rocky Mountains and equally diverse activities available from hiking, mountain biking, skiing, canoeing, or just unwinding amidst nature.

People choose to live here for one--or all--of these reasons, and they want to be able to have high-speed internet in these pristine areas.

Fiber Is Finally Here

Highline was established to solve the internet problem of the unserved, underserved, and unhappily served households in a variety of areas in Colorado starting with the new fiber build areas of Pueblo and Pueblo West, Burland/Bailey, Staunton/Pine, and Grand Junction, and legacy areas of Rye, Colorado City, South Park, Hartsel, and Fairplay.
