Thornton is a north metro city, mostly in Adams County, about 10 miles north of downtown Denver. Developer Sam Hoffman started building it in 1953 as a planned community of affordable starter homes, and it incorporated in 1956. It has grown steadily north since then, so you can drive from 1950s ranches to brand-new subdivisions without leaving the city.

Homes in Thornton

South Thornton, closest to Denver, has the original 1950s and 1960s brick ranches and bi-levels on small, tidy lots. The middle of the city filled in through the 1980s and 1990s with two-story homes and townhome communities. North Thornton, past 136th Avenue, is where most new construction is happening today, often in master-planned neighborhoods with parks and trail networks.

Getting around

The N Line commuter rail opened in 2020 with Thornton stations at 88th Avenue, 104th Avenue and Eastlake at 124th, and it reaches Union Station in under half an hour. I-25 runs through the west side of the city, and E-470 gives a direct route to Denver International Airport.

Shopping and parks

Denver Premium Outlets sits at I-25 and 136th Avenue, and big-box shopping lines 104th Avenue and the I-25 corridor. Carpenter Park and its recreation center are among the city's main gathering spots. Eastlake, an old farm settlement now inside Thornton, still has its grain elevator and a small lake.
