Unfortunately, this could be not enough.

~$ mkdir -p /tmp/testdir/subdir/scndsubdir
~$ cd $_
/tmp/testdir/subdir/scndsubdir$ rm -fR /tmp/testdir
/tmp/testdir/subdir/scndsubdir$ pwd
/tmp/testdir/subdir/scndsubdir
/tmp/testdir/subdir/scndsubdir$ cd ..
cd: error retrieving current directory: getcwd: cannot access parent 
directories: No such file or directory

For this, you could use PROMPT_COMMAND feature:

validCurrentDir() { 
    local __vCD_pwd=$PWD;
    while ! [[ -d $__vCD_pwd ]]; do
        __vCD_pwd=${__vCD_pwd%/*};
    done;
    cd $__vCD_pwd
}

~$ PROMPT_COMMAND=validCurrentDir

~$ mkdir -p /tmp/testdir/subdir/scndsubdir
~$ cd $_
/tmp/testdir/subdir/scndsubdir$ rm -fR /tmp/testdir
/tmp$
