As part of the City of Tucson Department of Transportation's Downtown Links Phase III project, CenturyLink will begin relocating their existing facilities located within the project limits, the City of Tucson said in a media release.

The CenturyLink work will consist of relocating several existing underground vaults located within City of Tucson right of way, followed by a year of splicing fiber and copper communication lines which are housed in the new vaults.

The CenturyLink work will take place in an area bounded by Fourth Street on the north, Sixth Avenue on the east, Toole Avenue on the south and Ninth Avenue on the west.

The first phase of work, vault relocation, will require heavy construction and include road closures and lane restrictions. Work is scheduled to begin on Monday, July 27, 2015 along Seventh Avenue between Fourth Street and Toole Avenue. Parking will not be permitted on Seventh Avenue between Fourth Street and Toole Avenue.
