When the federal highway agency tasked with building the new freeway project in Nevada announced plans to begin construction on it, the news caused consternation in the region.

A few days after the announcement, a letter arrived from the National Transportation Safety Board, the federal agency tasked to oversee the project.

“It is not yet clear what action will be taken,” the letter said.

The NTSB did not respond to questions about the status.

The agency’s letter was addressed to the federal government’s Transportation Safety and Infrastructure Protection Agency, which was tasked with implementing the project, according to documents reviewed by The Intercept.

The letter, which the Federal Highway Administration said was sent on April 26, 2017, does not address the state of Nevada.

But in a recent letter to a Nevada state lawmaker, the agency said the project would likely be completed by the end of 2021.

In a statement to The Intercept, the NHTSA said it had not yet seen the letter.

“The Federal Highway Agency has been in close contact with the Nevada Department of Transportation, and we have been actively monitoring the project’s progress, including through a review of existing documents,” the agency wrote.

The NHTSB has said it would take action if necessary.

A timeline for the construction of the new interstate project, the first in a new project, has not yet been set.

But a recent study conducted by the University of Nevada, Las Vegas found that Nevada’s highway system has been able to maintain a two-lane highway with two lanes of traffic for the past 25 years.

The highway, which would be constructed in Nevada’s largest city, Las Cruces, is expected to cost about $8 billion.

“I don’t think it’s a good investment,” Las Cruce resident Jennifer Bickford told the Las Vegas Review-Journal last year.

“And it will make people feel like they’re paying more for this road.

It’s not worth it.”

The NHSB said the highway will be built as part of a larger project, which will likely include new roads, bridges, and tunnels.

The project is scheduled to be completed in 2019, but officials said they are looking to have it completed in 2021.
