Credits to Jared and Terri for this. Clicking the link above will take you to bit.ly, until you log in (see me, Michelle Hoelscher or not sure who else can). Then you get TTI short URL capabilities.
Dragging a URL in creates a new short URL. Plus, you can customize the short URL to something that makes sense: e.g., for a link to an NCHRP report on the TRB website, http://tti-tam.us/nchrp-684.
bit.ly also automatically creates a QR code, but if you need a vector image or a high resolution for printing, use the QR generator here.
