Downtown Links Phase 1

Downtown Links Phase 1

As part of the Downtown Links Phase 1 project, Borderland constructed a new two-barrel 12’x10’ Reinforced Concrete Box Culvert (RCBC) within 8th Street, from 6th Avenue to 3rd Avenue, while working around some of Tucson’s oldest sewer lines, heavily traveled roadways, historic buildings, and railroads.  Extreme caution and precision construction techniques were used to place new lines under existing water lines, sewer lines, underground electric lines, storm drains, and low-hanging overhead electric lines.

Project Details

“We want to give a big ‘thank you’ to Borderland Construction and their subcontractors for completing a very difficult job in a very confined work area.”

Tom Fisher, Project Manager - City of Tucson, Department of Transportation

Community Benefits

The 8th Street drainage improvement project was the first of the multi-phased corridor project.  The new drainage system facilitates the City of Tucson's future Downtown Links Corridor Project that will connect people and places, upgrade critical infrastructure, and improve transportation in the Downtown area.
