 Now, impact traffic. East and westbound C-470 are closed at Santa Fe for bridge work. You'll be using the off and on ramps as your detour until about 5 a.m. You've got nothing slowing you down on I-25 making your way through the tech center. I-70 across town between Golden and Aurora is looking good. You should be able to make a time on 36 between here and Boulder. The drive on 6 through Lakewood is easy, and there's nothing interfering with you on I-225.
