What does "clsd" indicate in this scenario

[Rod]

I have downloaded the current and "upcoming" Chart Supplement (formerly Airport/Facility Directory) files from the FAA web site.  Both of them have the following quote to which I am confused to what the meaning of "clsd" means in this quote:

"Rwy 17R–35L clsd tfc remain south of Arapahoe Rd and east of Interstate 25."

I read that as runway 17R-35L is CLOSED to TRAFFIC, but then does go on to say to remain south of a specific east/west road and east of a north/south highway, which does not make sense to me.  I do not think that runway 17R-35L is actually closed.  I ate lunch at the airport restaurant two weeks ago and saw traffic on that runway.  I am looking at KAPA (SW > Colorado > Denver > Centennial -- If you want to look at the chart supplement yourself.)

I look forward to learning what that passage is supposed to be informing me of. 

Thank you.

I believe it refers to "tight" traffic pattern, keep the pattern south of Arapahoe rd.

I think it refers to people flying the traffic pattern (practicing touch and gos), ie, "Centennial Tower, Mooney XXXXX, departing RWY 35L, closed traffic" meaning we'll remain in the pattern, left traffic for 35L

This is correct and so is marcopolo

Also, the AFD should have a page that defines the usage of all their abbreviations.  The old ones did.  There are a lot of abbreviations for two reasons.  Print costs used to be high and they would shorten anything they could.  Radio phrases can be shortened to get the point accross without being verbose on air.

Training in the 90's used closed traffic when a pilot was departing and staying in the traffic pattern.  This alerts other pilots how to best plan for their own entry into the traffic pattern.  The traffic pattern can get pretty full with a plane on each segment, downwind, base, and final approach.
