The nineteenth-century Greek revival courthouse sits at one end of the Gateway Arch National Park grounds, which is undergoing a major transformation under the CityArchRiver (CAR) 2015 project. Trivers was selected to improve the visitor experience by renovating the exhibit spaces, replacing building systems, and bringing those spaces to compliance with current accessibility and life-safety standards. Trivers worked closely with the National Park Service to phase the project so that the building and exhibits could remain open during construction. 6,700 square feet of galleries will be prepared for state-of-the-art exhibits. New elevators will bring the visitors up to the second floor, where they can view the exhibits in the rotunda and experience the renovated historic east courtroom.
In addition to interior improvements, access to the building had to be improved to meet Universal Design standards. Exterior pedestrian ramps designed according to the Secretary of the Interior’s Standards for Historic Preservation have replaced a single outdoor lift and allow all visitors to enter through both iconic porticos.
