Hey, I know that place. That's exactly what the old downtown area of my native city looked like while they were renovating all the streets (which took well over a year).
Also looks like Venice, just fill the hole with water.l and tourist will be pouring in.
Note: to be fair, after finishing the work in my city, those streets were all closed off to cars except for people who live there (not many) and deliveries for the local businesses.
