Lemmon Drive Capacity and Diverging Diamond Interchange

Lemmon Drive Project Logo

Project Description

The Regional Transportation Commission (RTC) of Washoe County, in coordination with the City of Reno and Washoe County, is moving forward with improvements to Lemmon Drive to increase capacity, improve safety and provide multimodal transportation choices.

SEGMENT 1 will widen Lemmon Drive from 4 lanes to 6 from Sky Vista Parkway/Buck Drive to Military Road. The proposed design will also improve traffic flow with longer left turn lane queues from southbound Lemmon Drive to Buck Drive and northbound Lemmon Drive to Military Road, plus an additional lane for right turns from eastbound Military Road to southbound Lemmon Drive. A continuous raised median will prevent left turns into or out of businesses. U-turn movements will be accommodated at Military Road.

A Diverging Diamond Interchange (DDI) will replace the Lemmon Drive and US 395 Interchange. A DDI will provide a safer and more efficient interchange for drivers and pedestrians. The proposed design will provide 4 lanes along Lemmon Drive along with improvements to each of the ramps.

For pedestrians and bicyclists, the proposed designs include a separated, 10-foot wide shared-use path along the west side of Lemmon Drive, an adjoining sidewalk along the east side and bike lanes in both directions. The DDI will include sidewalks through the raised center median islands along Lemmon Drive as well as designated bike lanes throughout.

Major Traffic Detours Coming to Lemmon Drive/US 395 in March 

Lemmon Drive Project detour construction map, March to July 2022

As part of the project, access to Lemmon Drive to and from US 395 will temporarily change as construction continues on the Diverging Diamond Interchange. The RTC appreciates the community’s patience during this closure. Closing the lower-volume movements will result in project completion approximately two months early, by August 2022, weather permitting.

Beginning in March and continuing through July, there will be new detours in place 24 hours a day, 7 days a week. Drivers will continue to be able to get on US 395 southbound from Lemmon Drive and exit US 395 northbound to Lemmon Drive northbound. These are the two most-heavily used traffic movements at this interchange.

All other traffic will have to follow detour routes:

  • For those traveling south on US 395, to access northbound Lemmon Drive, use the southbound US 395 Golden Valley Road off ramp to northbound US 395. Drivers can also use Stead Boulevard to Lear Boulevard to Military Drive to Lemmon Drive.
  •  For traffic coming from North Virginia Street, Northbound Lemmon Drive through traffic will use the southbound Lemmon Drive on ramp to US 395 to the Golden Valley Road off ramp to northbound US 395 to northbound Lemmon Drive.
  • Temporary traffic signals will be installed at the Golden Valley interchange to help accommodate additional traffic volumes.

SEGMENT 2 will widen the road from 2 lanes to 4 between Fleetwood Drive to Ramsey Way. Among the design considerations are accommodating future growth, including complete street improvements and providing safe, multimodal connectivity through bike lanes, sidewalks, and/or shared-use paths.

Design alternatives will also address the fact that a large portion of Segment 2 is located below the 100-year flood plain and has experienced flooding in recent years. An alternative analysis is in progress, which will advance three possibilities to a 15% design level to determine a preferred alternative.

Construction Costs

Both Segment 1 and Segment 2 are included in the RTC’s 2040 Regional Transportation Plan (RTP). Segment 1’s estimated construction cost is $10,000,000. The DDI’s estimated construction cost is $ 10,000,000. For Segment 2, the cost will be determined by the alternative selected .
