Since roughly 2017, the zoo has slowly been converting their old "four rectangle stacked" terrariums, into one large habitat. The first link below is an example. It should be noted that it didn't look like that prior to the latest renovation, however. Before creating the king cobra's newest home, the four terrariums were combined to be two horizontally, then later turned into one.
The link below that is the old king cobra exhibit, now home to a Yellow-tailed cribo.
