Interstates 225 and 270

Interstate 225

Interstate 225 is approximately 12 miles in length and connects Interstate 25 at the Denver Tech Center to Interstate 70 north of Aurora and southwest of Denver International Airport. This interstate could be used to bypass the traffic of downtown Denver, however, this stretch of road can be just as congested at Interstate 25.

Interstate 270

Interstate 270 is the northeastern connector from Interstate 25 to Interstate 70 spanning a total of seven miles. More often than not, this stretch of auxiliary interstate is used to bypass traffic at the 70/25 junction and to gain quick access to Commerce City.
