The design of the Gateway Arch Museum in St. Louis, MO USA with lighting design by Tillotson Design Associates, took home an IALD Award of Excellence. The panel of judges recognized JCDA’s ceiling design with integrated lighting as the highlight of the design. Tillotson Design Associates achieved JCDA’s desire for tuned lighting that would seamlessly mediate the 252’ transition between the entry at ground level and the Museum Arrivals Hall as it descends to the main museum galleries 23’ below.
