Nevada Department of Transportation Announces

Utility Location Work for Future Reno Spaghetti Bowl Project

CARSON CITY, Nev. – Drivers will see periodic single lane closures on local roads near Interstate 580 and the spaghetti bowl over coming weeks as the Nevada Department of Transportation conducts preliminary utility surveys in advance of future spaghetti bowl renovations.

Between April 27 and late May, the following periodic lane closures will take place. Lane closures will take place intermittently on different sections of the roads.


Majority of work will take place during the hours of 8 p.m. to 6 a.m., Mondays-Fridays:
– Mill Street from Golden Lane to I-580 northbound Mill Street off-ramp
– Second Street/Glendale Avenue, between Reservation Road and I-580/Second Street northbound off-ramp

Majority of work will take place during the hours of 7 a.m. to 5 p.m., Mondays-Fridays:
– Fourth Street, between Threlke Street and Ferrari Street
– Vassar Street, from approximately 500 feet east of Market Street to 500 feet west of Matley Lane

Only small sections of individual lanes will be closed at a time. The roads will remain open with minor travel delays to be expected. Business and residential access will remain available.

The work schedule is subject to change.

Crews will survey exact locations of underground utilities to help finalize engineering designs for future construction of the first phase of spaghetti bowl improvements.

Construction is tentatively scheduled to begin later this year.

Known as Spaghetti Bowl Xpress, the first phase of spaghetti bowl renovations will restripe eastbound Interstate 80 lanes between Wells Avenue and the Spaghetti Bowl and widen the eastbound I-80 to southbound I-580 Spaghetti Bowl ramp to two lanes. Auxiliary merge lanes and improved ramps will also be added on southbound I-580 between the Spaghetti Bowl and Plumb Lane, along with sound and aesthetic walls. Sections of pavement on northbound I-580 will also be repaired. 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.
