  • REMINDER: Southbound I-580 lane shifts/reductions in place since Jan. 17
    • Southbound I-580 will continue to be reduced to three lanes between the spaghetti bowl and Villanova Drive, with lanes shifted to the east to allow for demolition of aging interstate bridges.
    • Drivers should anticipate travel delays and new traffic patterns, and are advised to leave extra travel time and consider alternate routes.
    • Speeds will continue to be reduced to 55 mph.
    • Southbound I-580 from eastbound I-80 traffic will experience rapid merge to southbound I-580.
    • Eastbound I-80 to northbound and southbound I-580/U.S. 395 spaghetti bowl ramps intermittently closed overnight from 9p.m. to 6a.m. for bridge widening.
    • Intermittent overnight lane and ramp closures will take place nightly from 9p.m. to 6a.m. on northbound and southbound I-580 between the spaghetti bowl and Villanova Drive.

All construction activities and times are subject to change and are weather dependent.

The improvements are part of construction of the first phase of NDOT’s spaghetti bowl renovations, known as Spaghetti Bowl Xpress. Over the next two years, the eastbound I-80 to southbound I-580 Spaghetti Bowl ramp will be widened to two lanes and eastbound Interstate 80 lanes between Wells Avenue and the Spaghetti Bowl striped. On southbound I-580, auxiliary merge lanes and improved ramps will also be added between the Spaghetti Bowl and Plumb Lane, along with sound and aesthetic walls. The first phase of construction will not require relocation of any residences.

Additional interstate improvements will be built in prioritized phases through 2039 as funding is identified. Approximately 250,000 vehicles per day currently travel through the spaghetti bowl. The Reno-Sparks population is expected to increase 27 percent by 2040. Without the future improvements, population growth is anticipated to lead to travel delay increases of 53 percent through the Spaghetti Bowl.
