Below are the other alternatives considered.

Final Environmental Impact Statement

SPAGHETTI BOWL PROJECT FINAL ENVIRONMENTAL IMPACT STATEMENT (FEIS):  The National Environmental Policy Act of 1969, as amended (United States Code [U.S.C.] Title 42 Section 4332) requires that all federal agencies prepare a detailed environmental impact statement (EIS) for major federal actions that will significantly affect the quality of the human environment. The Federal Highway Administration (FHWA) is therefore required to prepare an EIS for proposals funded under its authority if such proposals are determined to be major actions significantly affecting the quality of the human environment.

FAQS

Why does the Spaghetti Bowl need to be improved?

The Truckee Meadows area (including Reno and Sparks) is experiencing a dramatic population increase. With new job opportunities appearing at a high rate, portions of Interstate 80, Interstate 580, and U.S. 395 are at capacity. This results in increased congestion and increased crashes. The Spaghetti Bowl was constructed between 1969 and 1971 when Washoe County had a population of about 130,000 people and about 90,000 vehicles per day used the Spaghetti Bowl. In 2015, the combined population of Reno and Sparks was about 327,000 people and the population of Washoe County was about 435,000 people (U.S. Census Bureau 2016). About 260,000 vehicles per day used the Spaghetti Bowl in 2016, making it the busiest interchange in northern Nevada. The Spaghetti Bowl services a growing metropolitan area. I‐580/U.S. 395 and I‐80 are important links connecting the Reno‐Sparks area with the San Francisco Bay area and Sacramento in California, with Salt Lake City in Utah, and with Carson City.

What is the Nevada Department of Transportation planning to do?

NDOT completed an Environmental Impact Study (EIS) for the entire Spaghetti Bowl Project and the Final EIS Record of Decision was approved on July 30, 2019. The project is anticipated to be built in five phases over 20 years with an estimated project cost over $2 billion. Phase 1, the Spaghetti Bowl Express, is a design-build project currently in the design stage with construction anticipated to begin late 2020.

What is the project location?

The interchange that connects I‐80 and I‐580/U.S. 395, known locally as the “Spaghetti Bowl,” is located in the cities of Reno and Sparks in southern Washoe County, Nevada. The study area includes the Spaghetti Bowl and a 5‐mile segment of I‐80 from the Keystone Avenue interchange east to the McCarran Boulevard interchange and a 7.3‐mile segment of I‐580/U.S. 395 from the Meadowood Mall Way interchange north through the Spaghetti Bowl to the Parr Avenue/Dandini Boulevard interchange. The project limits are: I-80 Western Limits: Sierra/Virginia/Center Street Interchange; I-80 Eastern Limits: Pyramid Highway Interchange; I-580/U.S. 395 Northern Limits: N. McCarran/Clear Acre Avenue Interchange; and I-580/U.S. 395 Southern Limits: Moana Lane Interchange

How long will the Spaghetti Bowl Project take?

Key Preliminary Dates

Phase 1 Spaghetti Bowl Xpress (2020-2023)

Phase 2 (2024-2028)

Phase 3 (2028-2034)

Phase 4 (2035-2037)

How can I participate and give my feedback?

NDOT appreciates comments and questions about the project. There are several ways to connect with the project team: Call: 775-636-4204 Email: info@ndotspaghettibowl.com or sign-up below for project newsletter.

I live by the Spaghetti Bowl/freeways. Will my house be affected by this project?

Phase 1 will not relocate any businesses or homes. NDOT identified a Preferred Alternative for the overall project, but final design may slightly alter which properties might be impacted in future construction phases. For more information about the right-of-way process, please view information HERE or contact NDOT’s Right-of-Way division at 775-888-7480.

What is the Spaghetti Bowl Xpress project?

Spaghetti Bowl Xpress (or SBX) is Phase 1 under the Spaghetti Bowl Project umbrella. Because the entire Reno Spaghetti Bowl project is so large-scale, it is being divided into phases. SBX will address one of the most dangerous portions of the current Spaghetti Bowl: the eastbound I-80 to southbound I-580/U.S. 395 ramp and southbound I-580/U.S. 395 from the Spaghetti Bowl down to Mill Street.

How long will the Spaghetti Bowl Xpress project take?

Updated SBX Schedule Coming Soon.
