# Under-construction roadsign LaTeX (vol1. TAOCP p. xi) Knuth

I've searched everywhere on how to include the following symbol found on page 11 of the first volume of The Art of Computer Programming by Knuth:

The dangerous bend symbol is \dbend or \textdbend but I am unable to find how to include the aforementioned image or symbol, as it seems not to be included in manfnt or any other.

This question came from our site for professional and enthusiast programmers.

There is no such symbol. It is actually an image. You can find it in taocpmac.

\def\beginconstruction{\medbreak
\begingroup
\noindent\hang\hangafter=-2
\smash{\hbox to0pt{\hskip-\hangindent
\lower\baselineskip\hbox{\epsfbox{\figdir/aux.301}}\hfill}}%
\sl}
\let\endconstruction=\endgroup


The file \figdir/aux.301 is the symbol you are looking for.

• From what i understand this is some file that Knuth had, I searched his website but could not find the files. would it be possible to get the symbol from somewhere? Or should I just get my own symbol. – Vyraj May 30 '17 at 16:41
