When you visit the arch you can take a trip on the inside to the top to look through the windows at an amazing view.

The arch was designed by Finnish-American architect Eero Saarinen in 1947; construction began on February 12, 1963, and was completed on October 28, 1965, for $13 million (equivalent to $77.5 million in 2018). The monument opened to the public on June 10, 1967.

For the technical mind, here is a good link for design and construction.

The two arch halves were installed and there needed to be one last piece, requiring the halves to be pulled apart.  The time capsule, containing the signatures of 762,000 students and others, was welded into the keystone before the final piece was set in place.


The arch was topped out as then Vice President Hubert Humphrey observed from a helicopter. A Catholic priest and a rabbi prayed over the keystone, a 10-short-ton, eight-foot-long (2.4 m) triangular section. It was slated to be inserted at 10 a.m. local time but was done 30 minutes early because thermal expansion had constricted the eight-and-a-half foot (2.6 m) gap at the top  by five inches (13 cm). Workers had to use fire hoses to spray water on the surface of the south leg to cool it and make it contract. The keystone was inserted in 13 minutes.  Only six inches (15 cm) remained. For the next section, a hydraulic jack had to pry apart the legs six feet (1.8 m).

By noon, the keystone was secured.

The arch was dedicated by Humphrey on May 25, 1968. He declared that the arch was “a soaring curve in the sky that links the rich heritage of yesterday with the richer future of tomorrow” and brings a “new purpose” and a “new sense of urgency to wipe out every slum.” “Whatever is shoddy, whatever is ugly, whatever is waste, whatever is false, will be measured and condemned” in comparison to the Gateway Arch.

  1. My father had a summer job with the National Park Service during the time that the arch was being built. As a result, my sisters and I were allowed to go up in the arch before it was open to the public. That’s always been a fond memory!
