The Arizona Department of Transportation, in conjunction with the Federal Highway Administration, is replacing the Interstate 19 bridge decks over Pima Mine Road in the town of Sahuarita.
The $4.5 million project, located approximately 15 miles south of Tucson and partially on the Tohono O’odham Nation’s San Xavier District, includes replacing the bridge decks on the northbound and southbound travel lanes and reconstructing roadway and bridge approaches.
The work also will include widening the southbound I-19 bridge, replacing guardrail end treatments, replacing pavement markings and other miscellaneous work.
Work is scheduled to begin in late March 2017 with little effect on traffic until mid-April, when the southbound I-19 entrance ramp from Pima Mine Road will close for the duration of the 13-month project. While the on ramp is closed, traffic will be rerouted onto local streets to access southbound I-19 using either Sahuarita Road or Old Nogales Highway.
During the project, I-19 will maintain two travel lanes in each direction and Pima Mine Road will remain open with occasional closures for removing the existing decks and setting girders. Traffic will be detoured during this work.
Other restrictions on Pima Mine Road will include lane shifts and flagging operations during lane closures and reduced speed limits
Access to the nearby Desert Diamond Casino and ASARCO’s Sahuarita mine will be maintained with only occasional brief delays.
Work is scheduled for completion in April 2018.
