TUESDAY: Bus Traffic Only on R Street?

It looks like R Street through Borderstan will be open only to bus traffic on Inauguration Day.
It looks as if the section of R Street NW through Borderstan will be open only to bus traffic on Inauguration Day. I have seen two signs on R Street (the one at 14th & R was on the ground this afternoon)… one at 14th and the other one at 17th. I haven’t seen an official notice anywhere–this is all I know. Anyone know anything?
