Lane closure on eastbound Interstate 10 frontage road at Prince Road in Tucson extended to Monday (September 12)

September 6, 2011

The Arizona Department of Transportation has extended the right lane closure of the eastbound I-10 frontage road to Monday (September 12). The frontage road lane closure located approximately 500 feet north of Prince Road, began on Wednesday (August 24) and was originally scheduled to end at 4 p.m. on Wednesday (September 7). Due to additional work required for the underground utility work, the closure will continue 24-hours each day until 4 p.m. on Monday (September 12).

The closure will allow crews to install a new 8-inch natural gas line to replace an existing 4-inch line and is part of the upcoming construction to widen Interstate 10 between Ruthrauff Road and Prince Road in Tucson.

Some of the improvements that are planned as part of this project include:

  • Widening the I-10 freeway to four lanes in each direction to accommodate increasing congestion and traffic.
  • Reconstructing the Prince Road traffic interchange so that Prince Road will pass over the Union Pacific Railroad tracks and I-10 and minimize delays for motorists.
  • Updating the entrance and exit ramps to provide better connections and improved access.
  • New landscaping along the project area.

Construction is anticipated to begin later this month and last approximately 26 months. As part of the project, the Prince Road underpass and ramps will close in January 2012 and will remain closed until the project is scheduled to be completed by late 2013.

The construction schedule is subject to change due to a variety of reasons, including weather, material availability and mechanical difficulties. ADOT advises drivers to proceed through the work zone with caution, slow down, and be alert for construction equipment and personnel.
