The "Q" subway extension, has been planned for 100 years, a ground breaking ceremony was held nearly 50 years ago, and excavation and construction has been going on for ten years. Now, the first phase, along Second Avenue, is open. The stations are light and airy, with generous art installations. The Station entrances are marked by glass canopies. Station levels are open and can be viewed from other levels. Author, architect, and realtor Carol Berens describes the stations in words and photos in the source article.
