Passage:Kentucky Route 1531 is a rural secondary highway that begins in northeastern Bullitt County and ends in northwestern Shelby County, but the route spends almost all of its length in the city of Louisville in eastern Jefferson County. The highway begins at KY 1319 (Kings Church Road) near Whitfield. KY 1531 heads northwest along Dawson Hill Road then turns northeast onto Routt Road to enter the city of Louisville and Jefferson County. The highway crosses Wheelers Run and Back Run and meets the eastern end of KY 1819 (Brush Run Road) south of the Routt neighborhood of Louisville. KY 1531 follows Sheckels Run to its crossing of Cane Run and reaches KY 155 (Taylorsville Lake Road) south of Fisherville. The highway runs concurrently with KY 155 northwest across Floyds Fork of the Salt River to KY 148 (Taylorsville Road), with which the route heads east through Fisherville and across Floyds Fork again.

Passage:The Nelson-Atkins Museum opened its Euro-Style Bloch addition in 2007, and the Safdie-designed Kauffman Center for the Performing Arts opened in 2011. The Power and Light Building is influenced by the Art Deco style and sports a glowing sky beacon. The new world headquarters of H&R Block is a 20-story all-glass oval bathed in a soft green light. The four industrial artworks atop the support towers of the Kansas City Convention Center (Bartle Hall) were once the subject of ridicule, but now define the night skyline near the new Sprint Center along with One Kansas City Place (Missouri's tallest office tower), the KCTV-Tower (Missouri's tallest freestanding structure) and the Liberty Memorial, a World War I memorial and museum that flaunts simulated flames and smoke billowing into the night skyline. It was designated as the National World War I Museum and Memorial in 2004 by the United States Congress. Kansas City is home to significant national and international architecture firms including ACI Boland, BNIM, 360 Architecture, HNTB, Populous. Frank Lloyd Wright designed two private residences and Community Christian Church there.
