If you use westbound I-80 near Waltham Way, plan ahead. Overnight lane reductions and ramp closures begin June 14.
Traffic impacts near USA Parkway are part of an interim project to extend the Waltham Way on-ramp to westbound I-80 and improve traffic merging prior to future widening of I-80.
Beginning the evening of June 14 through early September, drivers will see the following intermittent overnight impacts:
• Waltham Way on-ramp to westbound I-80 closed beginning the week of June 14 through August. The USA Parkway on-ramp to westbound I-80 will remain open as an alternative.
• Westbound I-80 Exit 28 off-ramp to Patrick/Waltham Way intermittently closed overnight through August.
• Westbound I-80 reduced to one lane from 7:30 p.m. to 5 a.m. on weekdays, with additional weekend lane reductions outside peak travel hours.
• Speeds reduced to 55 mph through the work zone, with periodic reductions to 45 mph during major work operations.
Drivers should allow extra travel time and use caution through the work zone.
The current Waltham Way on-ramp will be extended by approximately 2,200 feet through a public-private partnership between Storey County and Tesla. Storey County is funding eligible project costs through a reimbursement agreement with Tesla.
More than 2,000 vehicles use Waltham Way daily, merging with nearly 50,000 vehicles traveling I-80 each day. The extension will provide additional space for drivers traveling from USA Parkway and Waltham Way toward Reno-Sparks to merge more safely onto the interstate while improving overall traffic flow.
Traffic on this section of I-80 has increased more than 70% over the past decade. As development and employment continue to grow in the Tahoe-Reno Industrial Center (TRI-Center), the project will help improve traffic movement ahead of NDOT's planned widening of I-80 between USA Parkway and Vista Boulevard, currently anticipated to begin as early as 2027.
