The Hyatt Regency hotel in Kansas City, Missouri, is known for its iconic walkway that connects the two towers of the hotel. This walkway, which spans over a busy street below, has become a symbol of the hotel and a popular attraction for both guests and tourists.
The walkway was designed by engineer John D. Cooke and architect Jack D. Milligan, and it was completed in 1980. At the time, it was the largest atrium hotel in the world, with 1,100 rooms and a unique structure that featured the walkway suspended above the street below. The walkway was designed to be a visual centerpiece of the hotel, and it has become an iconic feature of the Hyatt Regency.
The walkway is made up of two levels: the lower level is a series of interconnected bridges, and the upper level is a suspended walkway that provides a bird's-eye view of the atrium below. The lower level bridges are adorned with plants, sculptures, and other decorative elements, while the upper level walkway is more minimalistic in design. Both levels of the walkway offer a peaceful respite from the hustle and bustle of the city below, and they provide a unique and memorable experience for hotel guests.
The walkway has also been the site of several tragedies. In 1981, a collapse of the walkway caused the deaths of 114 people and injured more than 200 others. This disaster led to a comprehensive redesign of the walkway, which was re-opened in 1984. Since then, the walkway has been inspected regularly and has undergone several renovations to ensure the safety of its guests.
Despite its history, the Hyatt Regency hotel walkway remains a popular attraction for both guests and tourists. Its unique design and central location make it a must-see destination for anyone visiting Kansas City. Whether you're staying at the hotel or just passing through, the walkway is sure to leave a lasting impression.
