BASH Man page conditional expressions:

       -d file
              True if file exists and is a directory.

This is also stated at https://www.gnu.org/software/bash/manual/bashref.html

The operator also returns True if the file exists and is a symlink to a directory

-bash-4.1$ file foo
foo: directory
-bash-4.1$ file bar
bar: symbolic link to `foo'
-bash-4.1$ if [ -d bar ]; then echo "bar is a directory"; fi
bar is a directory
-bash-4.1$ if [ -h bar ]; then echo "bar is a symlink"; fi
bar is a symlink
-bash-4.1$ bash -version
