The driving force of a project that Uptown Houston District has proposed to the city to transform Post Oak Blvd.? Big beautiful buses. With both residential and commercial developments like Skanska’s 20-story office building popping up along the major transit corridor and METRO’s Uptown/Gold Line nowhere in sight, the District has developed a $177-million project featuring light rail-like BRT to update Post Oak — a street “that has long outlived its original use,” says John Breeding, the District’s president.
