Adams County has secured $12 million in project‑development funding from RTD to advance the final 5.5 miles of the N Line extension, covering environmental review, corridor validation, and preliminary engineering needed before construction can begin.
This phase will modernize earlier design work and prepare the corridor for future state and federal funding opportunities, reflecting a strong regional commitment to finishing the voter‑approved FasTracks vision. The extension will include two new stations at York/144th Avenue and North Thornton/Highway 7, both areas already undergoing coordinated planning to support walkability, transit‑oriented development, and future growth.
The investment arrives at a pivotal moment for Adams County, which continues to experience steady population increases, rising economic activity, and significant job growth across multiple sectors. As one of Colorado’s fastest‑growing counties, Adams County benefits from a young and diverse workforce, strong employer expansion, and a strategic location connected to major highways, rail lines, and Denver International Airport. These factors drive increasing demand for reliable mobility options that connect residents to jobs, education, services, and regional destinations.
With this funding in place, Adams County and its regional partners are working to position the N Line as shovel‑ready, ensuring the corridor is prepared to compete successfully for construction dollars. Completing the extension will strengthen regional connectivity, support planned development, and deliver long‑awaited transportation benefits to residents who have been anticipating the full build‑out of the N Line.
