Built in 1914, Union Station Kansas City is a major attraction for culture, education, and entertainment. The facility is a historic landmark and civic asset that was extensively renovated and reopened to the public in 1999. Union Station is currently home to a science center, a planetarium, theaters, re s t a u r a n t s , a n d a b u s y A m t r a k station. In addition, Union Station regularly hosts traveling exhibitions and community events. B e c a u s e p a r k i n g a n d p e d e s t r i a n access to this bustling facility needed improvement, Union Station Kansas City Inc. wanted a new bridge to carry vehicles and pedestrians from the front of this grand building to the third level of the existing West Yards parking structure. The bridge was constructed in 2016 as a part of the $7.8 million western expansion project. An integrated and dynamic design- build project-delivery method allowed the client to provide input about the design as construction progressed. The expansion project also included a modernization of the streetscape in the "front yard" of this majestic building, an updated eastern plaza to incorporate the terminal for Kansas City's new streetcar system, and improved bus access to the facility for school groups. With these renovations, Union Station has truly returned to its roots as a transportation hub for the region. One of the most exciting features of the expansion project is a sprawling festival plaza for community-based events, located immediately north of the new bridge. The first outdoor extension of Science City, the science center in Union Station, is adjacent to the festival plaza and features interactive exhibits based on the concepts of simple machines. The new bridge includes a pedestrian overlook that extends toward the festival plaza and outdoor exhibit space. This overlook, designated as Kansas City's newest "selfie spot," also has stunning views of the downtown skyline to the north and the majestic National World War I Museum and Memorial to the south. The Design Process During the design process, Union Station's corporate, operations, and maintenance personnel provided critical input to determine the specific needs of the facility and its many events. Previously, the West Yards parking structure was only accessible by driving a circuitous route around the back of the building, nearly a half mile from the main entrance.
