2100 South Reconstruction

Located in the heart of Salt Lake City's Sugarhouse neighborhood, the 2100 South corridor required a full reconstruction from the ground up. The team executed every phase from demolition through surface reconstruction, signals, lighting, and final striping.  

The project demanded a contractor capable of managing complex phasing in a busy urban environment while keeping surrounding businesses and commuters moving throughout construction. As performance exceeded expectations, Salt Lake City expanded the scope mid-construction, adding $11.2M in water and sewer infrastructure upgrades. 

Need 

The 2100 South corridor aimed to improve traffic flow, enhance road safety, increase accessibility for all users, and replace aging water infrastructure that has reached the end of its service life.  

Decades of wear left the roadway with deteriorating surfaces, failing underground utilities – including critical water lines, rendering the street unable to reliably serve cars, transit vehicles, bicyclists, wheelchairs, and pedestrians.  

This investment was necessary to restore safe, efficient, and multimodal mobility while addressing essential public health and safety concerns tied to outdated infrastructure. 

Work 

• Reconstructed the full roadway from subgrade to surface, including a cement-treated base. 
• Installed comprehensive storm drain and water main upgrades, including 20 new water valves at the 900 East intersection. 
• Removed abandoned railroad ties and constructed new ADA-compliant ramps, gutters, crosswalks, benches, and sidewalks. 
• Installed streetlights, traffic signals, fiber optic conduit, signage, and pavement striping. 
• Planted 154 trees and reconfigured all landscaping.

Innovations 

• Demolished concrete was stockpiled and processed through an on-site crusher, generating approximately 2,000 tons of reusable aggregate. 
• Repurposed crushed concrete as road base, effectively diverting waste from landfills and reducing hauling and material costs.
