New Castle's Growth Story
New Castle has added significant residential development in the past decade — the community's I-70 access, lower land costs compared to Glenwood, and proximity to Glenwood Springs services have made it one of Garfield County's fastest-growing towns. New subdivisions on the bluffs above I-70 offer mountain views that Glenwood Springs can't match at comparable prices. The growth trajectory is upward.
