Tucson motorists need to be prepared for road restrictions this week on the newly widened section of Interstate 10 between Ruthrauff and Prince roads as crews begin final paving on the eastbound lanes to create a smooth driving surface, according to the Arizona Department of Transportation. Crews will return one week later to apply the new top layer of rubberized asphalt on the westbound lanes.

ADOT advises drivers to plan ahead and allow extra travel time when traveling on eastbound I-10, where there will be a reduced 45-mph speed limit through the work zone. For a complete list of restrictions this week, see below:

Eastbound I-10 will be closed between Ruthrauff Road and Miracle Mile from 9 p.m. Thursday, May 1, to 5 a.m. Friday, May 2. Traffic will be detoured to the eastbound I-10 frontage road.

Eastbound I-10 will be narrowed to two lanes, beginning 5 a.m. Saturday, May 3, through 9 p.m. Sunday, May 4.

The eastbound I-10 Ruthrauff Road on-ramp, Prince Road on- and off-ramps and Miracle Mile off-ramp will be closed around the clock from 9 p.m. Thursday, May 1, to 9 p.m. Sunday, May 4. Drivers may use the eastbound I-10 off-ramp at Ruthrauff Road and/or take the frontage road to the eastbound I-10 on-ramp at Miracle Mile.

The eastbound I-10 right shoulder between Ruthrauff Road and Miracle Mile will be closed on Friday, May 2, from 5 a.m. to 8 p.m.

The eastbound I-10 left shoulder between Ruthrauff Road and Miracle Mile will be closed from 5 a.m. to 5 p.m. Monday, May 5.

Westbound restrictions for next week’s final paving will be announced at a later date.

The final rubberized asphalt paving is part of a $76.4 million project to widen I-10 between Ruthrauff and Prince roads that began in September 2011. The project upgraded a two-plus-mile section of I-10 by increasing capacity, reducing congestion and improving traffic flow on this highly traveled corridor in Tucson. In addition, the newly reconstructed Prince Road traffic interchange, which now carries traffic over Union Pacific Railroad, reopened in March.

ADOT works to inform the public about planned highway restrictions, but there is a possibility that unscheduled closures or restrictions may occur. Weather can also affect a project schedule.
