There is an updated article (updated: May 18, 2017) in which you can easily link to places and directions using the new Google Maps.
You can use the route service and create the url as such :
https://www.google.com/maps/dir/33.93729,-106.85761/33.91629,-106.866761/33.98729,-106.85861
Use the double slash "//" between the markers to leave the position blank, for example, set a custom starting point.
Update
There is another great article here
