NDOT Spaghetti Bowl Xpress Traffic Control Update, August 28

Dear Stakeholder

NDOT has launched construction of the Spaghetti Bowl Xpress project as crews prepare to remove and replace aging concrete on I-580 northbound between Mill Street and the spaghetti bowl. On northbound I-580 between Mill Street and the spaghetti bowl, you will see a football-shaped work zone separating traffic on either side for worker and driver safety. Watch the video simulation HERE.

Ames/Q&D places temporary signage for the traffic shift on I-580 northbound.

Traffic Control

  • Lane shifts/reductions through December: I-580 northbound lanes are split and reduced between Mill Street and the spaghetti bowl.
    • Left-hand lanes are designated for through traffic traveling to U.S. 395 north of the spaghetti bowl.
    • Right lanes are for drivers accessing Interstate 80 and local interstate ramps such as Glendale Avenue.
    • Speed limits are reduced to 55 mph.
    • Drivers should anticipate moderate travel delays.
  • Additional overnight lane reductions 9 p.m. to 6 a.m. nightly through October.
  • Intermittent overnight ramp closures will also take place, with marked detours available.
  • Periodic single lane reductions will also take place on East Second/Mill streets near I-580 August through mid-October as above-ground utilities are moved underground in advance of road work.

Crews place barrier rail to guide drivers through the work zone and protect workers.

Look Ahead

  • Crews are preparing for the Reno-Sparks Indian Colony neighborhood wall construction with debris removal and temporary fencing.
  • Utility improvements will take place on Mill Street in September.
  • I-580 northbound pavement removals and grading.
  • Spaghetti Bowl Xpress project will substantially complete in 2022, followed by other phased improvements to the spaghetti bowl and 12 miles of metro interstate.
