US 50 has closed (west of Curecanti) most every work day, for construction; so Monarch Pass isn't even an option except on weekends.
Your best bet right now is to go (the wrong way) to Grand Junction and then take I70 into Denver.
And, you are on the western slope. So, there really isn't a way to avoid a 10,000+ pass, to get to Denver.
