• U.S. 36, also known as the Boulder
Turnpike, provides quick northwest access
between downtown Denver and Boulder.
• Metro Denver is at the crossroads of three
major interstates – I- 25 is the north-south route, while both I- 70 and I- 76
provide east-west access.
About three-quarters of the beltway around
metro Denver has been completed, and an
Environmental Impact Statement (EIS) study is
currently underway to look at options for
completing the last beltway portion in
northwestern Jefferson County. As of March
2011, the beltway includes:
• C-470 ( 26 miles) extends from I- 25 in
the southern metro area to I- 70 near
Golden. The C-470 Corridor has
emerged as one of metro Denver’s
major economic corridors, providing a
vital connection between the mountains
and the southern suburbs and Front
• E-470 (toll road, 47 miles) runs along
the eastern perimeter of the metro
area and extends from C-470 at I- 25
(south of Denver), runs east and then
north through Aurora, passes along
the western edge of the Denver
International Airport, and turns west,
terminating at I- 25 on the north end
of the metro area.
• Northwest Parkway (toll road, 11 miles)
connects with E-470 and I- 25 at 157th
Avenue in metro Denver.
