On Monday, April 22, the world premiere red carpet arrival of ‘Avengers: Infinity War’ was held on Hollywood Boulevard. The event took place inside a 40’ x 870’ clear span structure. Construction of the tent was accomplished in a total of 10 hours. The structure was the largest installations on The Boulevard of the year, and longest of all time. Since cross traffic was to remain open at an intersection crossing The Boulevard until the hours before the event, precise measurements were needed to leave two bays of the structure unbuilt and connected right before showtime.
