All over the historic center, streets have been pedestrianized, buildings have been restored, and new museums opened. In the 1990s, after many years of controversy, protests and even riots, most street vendors were evicted to other parts of the city. The impetus to bring things back to the city center included the construction of the new mayoral residence just off the Zócalo. The government has buried electric and telephone cables in the area, and replaced old asphalt with paving stones. It has also installed nearly 100 security cameras to help with crime issues. This paved the way for the opening of upscale eateries, bars and fashionable stores. Also, young people are moving into downtown lofts. To attract more tourists, there are new red double-decker buses.
