Tohono O’odham PIR 21(4)

Dibble CM provided construction management services for this remote 11.5 mile stretch of 45-year old roadway. This recently completed section of Federal Route 21 will help members of the Tohono O’odham Nation make it safely between Santa Cruz Village in the Pisinemo District and Papago Farms in Chuckut Kuk District. The road will also provide a more accessible and safer way for border patrol agents to reach their station located at Papago Farms.

Existing road conditions

Construction on the project began in March 2020 and finished on July 31. Material from the existing road was removed and pulverized to use as the base material for repaving. The project also included hot asphaltic concrete, drainage structures, dip crossings, fencing, cattleguards, gates, signs, striping, and other miscellaneous work as called for in the design plans and specifications for this project.
