It is the tallest building in the world with a roof top helipad. It has a total of 75 floors which include 73 above ground and two parking garages underground. The building was designed by Henry Cobb with construction starting in 1987. US Bank Tower opened two years later in 1989. The estimated cost of construction was $350 million.
The tower is well known by citizens of Los Angeles and is referred to as the Library Tower. The name changed to US Bank Tower in 2003 when US Bancorp leased the building.
