There are a number of URs for ramp closures at I-635 to eastbound I-70 ramps.

I found the following information on the closures:
“Both northbound and southbound I-635 to eastbound I-70 ramps will be closed from late March
through the end of 2015.”
“From late March to approximately late July, the eastbound I-70 to Kaw Drive ramp will be closed”
The documentation can be found here:
