As if the 1-25 & 6th. Ave construction congestion wasn't bad enough, CDOT has decided to put up temporary ramp metering again on the Santa Fe NB ramp to I-25 NB.
They will be in operation for both your morning and evening commuting pleasure every day this week.
So, if your normal route takes you this way, and you like sitting in traffic and staring at the brake lights in front of you, continue on your normal route.
Otherwise try to figure out a different way to go, my predictions are that traffic on NB Santa Fe will back up to at least Florida, and peak times will encroach toward Evans.

Have fun out there and by the way, Merry Christmas from CDOT.
