16th Street, formerly the 16th Street Mall, is a 1+1⁄4-mile (2.0 km) pedestrian and transit mall in downtown Denver, Colorado, opened in 1982 to ease bus congestion and improve pedestrian access. The original portion was designed by architect I. M. Pei, its granite paving forms an intricate pattern inspired by the western diamondback rattlesnake and Navajo weaving. The pedestrian only parts of the street extend from Wynkoop Street to Civic Center Station at Broadway, with the 16th Street FreeRide shuttle bus stopping at every intersection and extending to Union Station. The street hosts hundreds of stores and restaurants, including the Denver Pavilions shopping center.
