Good roads for intervals in boulder

[axlvid23]

I know I could a. find a map, b. go explore the city I live in, or c. buy rollers, but school puts me at a loss for time/money. So if any of you boulder locals know of a good, low traffic road for 5-10 minute sustained intervals, chime in.
Thanks for your help,

Alex

well, Hwy 36 north side of Boulder to Lyons is a great road.
