The Pearl area of Downtown Portland was formerly used for warehousing, light industrial purposes and a railroad yard and was known as the "Northwest Industrial Triangle"
In the 1990s, an elevated portion of NW Lovejoy Street from the Broadway Bridge past NW 10th Avenue was demolished, opening dozens of surrounding blocks (including some brownfield sites) for development, which peaked in the 2000s. The viaduct was notable for having columns painted by a railroad watchman who worked below; two of them have been saved. The increasing density has attracted a mix of restaurants, brewpubs, shops, and art galleries, though in some cases pioneering tenants have been priced out of the area. The Portland Streetcar opened in 2001
