I-580/U.S.395 Spaghetti Bowl Bridge Resurfacing

Overnight lane closures will be in place on Interstate 580/U.S. 395 in the Reno spaghetti bowl area as the Nevada Department of Transportation resurfaces bridges.

Lanes will be reduced on I-580/U.S. 395 through the spaghetti bowl between approximately 9 pm and 5 am Sunday evenings through Friday mornings. The construction-related lane closures will take place this fall and next spring. Periodic, overnight spaghetti bowl ramp closures will also take place as part of construction, with marked detour routes available. A minimum of one lane will always be available in both directions of interstate.

The approximately $1.5 million project by Truesdell Corporation will rehabilitate the aging roadway surface approaches to five bridges near the spaghetti bowl for a smoother and safer drive.

The work is part of  NDOT's proactive pavement preservation program through which state roadway surfaces are preserved and resurfaced before reaching time for more extensive and costly repairs. 

Nevada bridges have been named the nation's best in the last two years by ranking of U.S. Department of Transportation bridge data.

USA Parkway

The Nevada Department of Transportation, in cooperation with the Federal Highway Administration, is extending USA Parkway from the current end of pavement south to U.S. 50 near Silver Springs in Lyon County. The extension will complete the 18-mile-long roadway and provide an additional connection between I-80 to U.S. 50. The new alignment will enhance accessibility and mobility between Lyon and Storey counties, as well as provide transportation infrastructure to support existing and planned land uses and economic development in both counties.USA Parkway

Carson City Freeway Phase 2B-3 from Fairview Drive to South Carson Street

Construction on phase 2B-3, construction of the freeway from Fairview Drive to South Carson Street, began in 2015. For project details, please go to: www.ccfreeway.com .

Roadway Resurfacing on South Carson Street, Carson City

Overnight lane closures will take place on South Carson Street between Fairview Drive and Overland Street Sundays through Fridays from 8 p.m. to 6 a.m. One lane in each direction will always remain open, and business access will remain available.

The nearly two miles of roadway will be microsurfaced for enhanced roadway smoothness and durability. The improvements will help protect and prolong pavement life by resealing the roadway with a new top layer. Certain sidewalk ramps will also be enhanced for better accessibility.

The approximately $1.2 million project by Sierra Nevada Construction is scheduled to finish in the fall of 2016. This section of Carson Street was last resurfaced in 2002.  The roadway currently serves as a freeway connection for those traveling between the I-580 Carson City Freeway and south of Carson City. The improvements will help preserve the roadway surface of the segment of South Carson Street before it is moved from state ownership to Carson City ownership in 2017. An average of 44,000 vehicles daily travel the road daily.

Cave Rock Tunnel Extension and Water Quality Project

The Nevada Department of Transportation is taking preventative measures to ensure the future safety of the traveling public within the Lake Tahoe Basin.  As a result of large scale rock fall that occurred in early February 2015 and due to the threat of large diameter rock fall in the future, NDOT will construct a tunnel extension / rock fall shelter on the north side of the westbound Cave Rock Tunnel.  This approximately 60' long, 27' tall, flat-topped structure will protect the traveling public by catching falling rocks all while blending into the natural surroundings with colors, patterns, and textures matching the adjacent rock faces. 

Additionally, stormwater quality improvements will be made from approximately one mile north of Cave Rock at Milepost 8.4 through Milepost 11.4.  Improvements include paved shoulders, new drop inlets, new sediment filtration systems, slope scaling, and barrier rail.

Construction will continue through Fall 2016.

I-580 Road Improvements Through Washoe Valley

The Nevada Department of Transportation has finished construction of an auxiliary merge lane from Alternative U.S. 395/Eastlake Boulevard to southbound I-580 in north Carson City. The work was part of a project to repave the aging roadway surface, seismically retrofit bridges and make other improvements on Interstate 580 in Washoe Valley. The merge lane was extended 2,700 feet, providing additional space and safety to merge.

The project is also seismically retrofitting and enhancing the I-580 Bellevue Road bridge and Eastlake Boulevard underpass as part of NDOT's continuing effort to retrofit older bridges for enhanced safety and stability during potential earthquakes. The Bellevue Road overpass will be closed intermittently during those road improvements.

The approximately $15 million project by Q & D Construction is scheduled to complete in the fall of 2016.  Approximately 32,000 vehicles travel I-580 daily in the area.

I-580 Reconstruction Project

The approximately $12.1 million project by contractor Q & D Construction improved southbound I-580/U.S. 395 from Glendale Avenue to Moana Lane. Aging concrete roadway slabs last constructed more than 30 years ago have been replaced between Mill Street and Villanova Drive on I-580 southbound. Other areas of existing roadway concrete that are not being replaced have been resurfaced on both directions of the interstate. In addition, select bridges are being seismically retrofitted and interchange crossings below the freeway are receiving Americans with Disabilities Act accessibility enhancements. The project is expected to complete in summer 2016, providing an enhanced concrete southbound I-580 roadway surface. More than 140,000 vehicles travel the stretch of I-580 daily.

Mt. Rose (SR 431) Truck Escape Ramp

NDOT has begun a project by to enhance the State Route 431 Mt. Rose Highway truck escape ramp. The truck ramp, located on the westbound side of the highway in Incline Village, will be converted from the current rock surface to asphalt. A series of six pre-tensioned drag nets will be added to the truck ramp to catch the front grill of runaway vehicles and help safely absorb the impact to slow, then ultimately stop, the vehicle. The asphalt surface of the truck ramp will be heated to ensure that snow or ice does not hamper use of the nets during winter months. Two roadside flashing signs and one large overhead digital message sign will also be installed to alert drivers when a vehicle is in the truck ramp. The approximately $4.6 million project by Q & D Construction is scheduled to complete in the fall of 2016. Click here for more information.

***Any truck over 26,000 pounds or with air brakes is prohibited on SR 431 westbound
