UPDATE: NDOT says I-580 between Carson City and Washoe Valley is back open, earlier than expected. NV Energy crews completed work early to replace power lines over the interstate, and now the power is back on for around 11,000 Lake Tahoe customers. The interstate reopened around 9:30 a.m. Sunday, but was due to stay closed until 1 p.m. 

NDOT wants motorists to anticipate heavy traffic Sunday afternoon, as more community members may access the roadway.

Anyone planning on heading to or from Carson City this weekend may need to take a detour as crews repair a downed power line.

NV Energy, along with the Nevada Department of Transportation (NDOT) plan on doing a hard closure of I-580 through Washoe Valley and part of Carson City, all to fix power lines and restore normal power to Lake Tahoe residents.

“This is our normal line that feeds up to the Incline area, and with winter coming it’s a high reliability issue for us, it's very important that we get that line back in service before winter," said Brian Costello, Director of Delivery Operations for NV Energy.

Customers in the Incline are being supplied power through Liberty Utilities, a California energy company. The outage was due to a RAVEN helicopter, owned by the Washoe County Sheriff's Office, that clipped the power line and started a fire on the 27th of October.

The planned closures will happen on Saturday and Sunday from 7 a.m. to 1 p.m. It runs on I-580 starting at Bowers Mansion and runs all the way down to US50 East/Williams Street. All of the on and off ramps will be closed between the areas. Alternate 395 will also be closed a little before Hobart Road.

“It's important for the community to know that there will be no through traffic allowed through the Lakeview area," said Meg Rogonese, Public Information Officer for NDOT.

There are a couple of different routes that you can take to or from Carson City:

  • Taking I-80 eastbound to USA Parkway, then down to US50 and finally West to Carson.
  • The second is heading up Mt. Rose highway to SR28 then south to US50 and finally east to Carson Street.
  • And the last one is heading up Geiger Grade through Virginia City and then West to Carson City.

While these may take extra time, NDOT tells us these are the only routes available between 7 a.m. and 1 p.m. Saturday and Sunday. NV Energy plan's on having the repair work done by 1 p.m. on Sunday, but should anything change you can always stay up to date on air and online at ktvn.com.
