Avoid I25 at all cost - through 2022. 21 miles of nasty construction between Monument and Castle Rock. Narrow lanes, no shoulders, and very bad roadways.
Use US83 North to Parker where you can pick up e470 North. US83 is mostly 2-lane, but a very pretty drive between Colorado Springs and Franktown. E470 is a toll road, but worth the expense to avoid the I25 traffic through Denver. It's a "license plate toll" road so no stopping to pay. They'll mail you a bill.
A pleasant alternative is US24 East to Limon, then Colorado 71 north to Brush where you pick up I76. It's mostly two-lane through the rolling Colorado prairie, but not a bad drive at all.
