The Missouri Department of Transportation announced last December that it planned to replace the Broadway Bridge over Interstate 670. The job came with an added degree of difficulty: The September opening of the Kauffman Center for the Performing Arts. People — important people — would notice if the "road closed" signs were in place past the deadline. Workers did, in fact, lift the barricade in time for the center's debut. Like other new bridges over I-670, the $4.9 million Broadway overpass was designed with pedestrians in mind. The sidewalks have been doubled in width and feature aesthetically pleasing barriers designed by architectural firm El Dorado. The fence consists of three layers of metal mesh and includes LED lighting. To stand apart from the gray and gun-metal blue that dominate the surroundings, El Dorado's architects incorporated the color yellow into the design.
