This design-build project consisted of reconstructing 12.5 blocks of downtown Denver’s iconic 16th Street, a pedestrian and transit corridor at the heart of the city. This project is the first major renovation of this landmark since its opening in 1982. Work included full replacement of aging water and storm systems, construction of an ADA-compliant granite paver transitway, and integration of modern drainage and utility corridors beneath the surface.  

A primary driver for the project was the need to address deteriorating infrastructure and enhance safety, mobility and aesthetics, while also creating more opportunities for public enjoyment with interactive art installations and seating areas. The project was designed to honor the original design from renowned architecture firms I.M. Pei and Associates, and Olin.

Executing major reconstruction within a high‑traffic downtown environment required intensive planning, stakeholder alignment and precise sequencing. PCL maintained uninterrupted access to local businesses through detailed phasing and coordination strategies.

A central achievement included installing more than 950,000 new granite pavers, replicating the historic Navajo rug and diamondback rattlesnake pattern that defines the identity of 16th Street. The redesigned corridor improves mobility by relocating transit lanes to the center of the street, allowing for wider pedestrian walkways and new amenity zones that support leisure, entertainment, outdoor dining and tourism.
