While the supercharger network is massive and an amazing undertaking and system, the map cannot be relied on with regards to "pending" or "coming soon" or "target" dates, only what actually is opened. Tesla will list a location as coming soon and with a season and year listed, and simply at the end of each season/year, change the year to the next year.
For example: Calabasas, CA lists "Coming Soon" and "Target opening in 2019", however, in 2017 it listed 2017, in 2018 it listed Summer 2018 then changed to Fall 2018, before being changed to "Target opening in 2019". Many many other locations have had the same thing, for example, Santa Barbara, Westwood, Beverly Hills, Simi Valley, venice, Sherman Oaks, etc, etc.
And as reported in a SoCal supercharger thread, for example, for the Calabasas location (similarly to other So.Cal locations), the supercharger equipment was delivered and actually at in dozens of boxes behind the Ralphs shopping center (in the delivery area) at which they were to be installed, and after being there a year (with the boxes falling apart), Tesla let the installation permit expire and then removed the equipment.

It seems Tesla has stopped the roll-out of many of the listed urban supercharging locations. Some big, media attention locations, like the new location in Las Vegas have been completed, but the map as to "Target opening" or "coming soon", especially for city/urban locations, are mostly false listings. Maybe due to cash issues?
