answer: To improve pedestrian safety, several pedestrian footbridges were built in the 1990s.  After a car accident in 2015, 800 bollards were installed along Las Vegas Blvd. in 2017 (later shortened in 2019 due to driver feedback).  Studies in 2012 and 2015 led to improvements like LED lights, ADA ramps, wider sidewalks, and removal of obstructions (both permanent and temporary, like street performers).
