Daniel Burnham was chosen to design the Washington Union Station, and he decided to use the Beaux-Arts style with arches. The inside view of the building is the most astonishing to me. The original construction of the station cost over $25 million and later had to be reconstructed. The reconstruction cost over $160 million. The interior wood of the building was completely solid mahogany. This building is what set the mode for Washington’s architect to come in the future. This station opened in 1907 and became one of the busiest stations in the United States. The white granite that was used to construct the outside of the building had never been used on a building before. Daniel Burnham was the first to use this granite in such a way. The arches of the Union Station are a symbol of the gateway that the station is.
