UCLA Facilities Management is circulating the message:
Traffic Notice Full Closure
The Montana Avenue off-ramp from northbound I-405 will close permanently at 6 am on Monday, November 25th. The I-405 northbound off-ramp to Sunset Boulevard will be reopen at the same time.
When: Monday, November 25th at 6 am
Where: I-405 Northbound Off-ramp to Montana; I-405 Northbound Off-ramp to Sunset

When yours truly went to the Facilities Management website from which this message is supposed to have derived, there was no mention of a permanent closure of the Montana off-ramp. The website from Metro about the 405 project also had no mention, at least none I could find.
Well, perhaps there is some greater meaning in having no exit on Montana:
