Project Update

The project is expected to complete, opening the final segment of freeway to traffic, in early August 2017.

NDOT invites the community to celebrate the upcoming opening by taking part in a free fun walk, run and bike event on July 22 from 9 am to noon. Click here for details!

Traffic Control

  • Lanes may be reduced and periodical traffic shifts should be anticipated on both south Carson Street and U.S. 50 as the intersection is reconstructed to connect to the last leg of the Carson City Freeway.

  • The future four-way intersection will be controlled by a traffic signal coordinated with surrounding signals for optimum traffic flow.

  • Lanes will also be permanently reduced to one lane when entering I-580 from eastbound Fairview Drive.

Current Project Information

Phase 2 of the Carson City Freeway will add the remaining 4.9 miles of controlled access freeway from U.S. 50 East to the southern connection at the existing U.S. 50 West - Tahoe Junction / Carson Street intersection. The Freeway will also be designed for two lanes in each direction with provisions for future widening in the median.

Phase 2B MapConstruct Freeway from Fairview Drive to South Carson Street (Phase 2B-3)

Phase 2B-3 will construct the freeway from Fairview Drive to the signal at US 50/South Carson Street. Upon completion of this phase, the freeway will be open for travelers to use between Fairview Drive and South Carson Street. This project began in spring 2015. The construction duration for Phase 2B-3 is anticipated to last approximately 24 months (two construction seasons) and will consist of the following elements:

  • A four-way at grade signalized intersection at US 50/South Carson Street
  • All remaining drainage facilities for roadway and offsite storm water runoff on the project, including drainage channels, a detention basin and box culverts
  • Roadway earthwork and final grading from Fairview Drive Interchange to South Carson Street, including major excavation and embankment.
  • Roadway paving
  • Landscaping
  • Sound walls
  • Signals, lighting, signing and pavement striping
  • Construction of sound walls


Project Benefits

  • Completion of I-580 from Reno to Carson City
  • Connect Carson City, the state’s capital, to the Interstate System
  • Decrease congestion
  • Shorter commute times
  • Improve safety
  • Accommodate projected local traffic
  • Meet stakeholder/public transportation expectations
  • Reduce idling and vehicle emissions
  • Beautify the corridor

Previous Construction

Phase 1 of the project constructed the northern half of the Carson City Freeway. This approximately four-mile portion of the project starts north of Carson City near the East Lake Boulevard interchange in Washoe Valley. Existing U.S. 395 was widened in the northbound direction to provide for the addition of a truck-climbing lane up and over the hill coming out of Carson City to the East Lake Boulevard interchange. A median barrier rail was installed in this location to enhance safety. After connecting into existing U.S. 395 near Bonanza Road in north Carson, the freeway continues on new alignment to the point where it intersects with U.S. 50 East.

Snyder Avenue Bridge, Grading and Drainage Improvements (Phase 2B-2)

Phase 2B-2 began construction in early 2013 and completed in summer 2014. This phase of the Carson City Freeway consists of the following elements:

  • Grade separated crossing (no freeway access) at Snyder Avenue, with Snyder Avenue constructed over the future freeway.
  • Drainage facilities for roadway and offsite storm water runoff in the southern leg of the project, including drainage channels, detention basins and box culverts.
  • Roadway grading in the southern leg of the project to accommodate drainage and utilize fill material from detention basins.
  • Relocation of Carson City’s utility facilities impacted by construction.

Future Construction

South Carson Street Interchange and Final Freeway Connection to US 50 (Phase 2B-4)

Phase 2B-4, pending availability of funding, is expected to advertise for construction in the mid to late 2020's. Upon completion of Phase 2B-4, the construction of the I-580/U.S. 395 Carson City Freeway Project will be complete. This phase of the Carson City Freeway will construct the interchange at South Carson Street and consists of all remaining construction elements for the Carson City Freeway project, including:

  • South Carson Street interchange; including the construction of bridges over South Carson Street
  • Roadway earthwork and final grading on the west side of South Carson Street
  • Roadway paving
  • Landscaping
  • Retaining walls
  • Signals, lighting, signing and pavement striping
