I guess I wouldn't be too quick to make assumptions about which parts of the process are fast or slow for a specific location (unless one has insider knowledge from that department inside Tesla). There are a lot of parties and factors involved in Supercharger construction; landlords, local governments, electrical contractors, subcontractors (trenching, paving, etc), utilities (metering, transformers), supply chain issues (transformers and probably other components), off-site upgrades to electrical grid, and on and on. Each of those are affected by numerous factors from the weather, staffing or shifting priorities. For this particular site, there is no reliable way to predict when it might open; could be a few weeks or a few months.
