The U.S. 50 Phase 2 widening project adds a key link to one of the most traveled corridors in Lyon County. The project will help reduce crashes, increase safety for the traveling public, provide connectivity and mobility by designing concrete High-T intersections at county roads. Adding these elements on U.S. 50 will help control access to provide safety to the travelling public, which is similar to the U.S. 50 Phase 1 Project.
The scope of the project is to design and construct a new four-lane divided highway which will connect to the previously-constructed Phase 1 widening project. The project will begin at Roys Road and end at the junction of U.S. 50 and U.S. 95A in Silver Springs. The design will also consist of intersection lighting, drainage improvements, and signage.
Other Project Benefits
- Replacing the stop condition at U.S. 50 and U.S. 95A in Silver Springs with a new single lane concrete roundabout
- Extending the US 95A northbound truck climbing lane
- Landscape and Aesthetics improvements
- Connection to the existing USA Parkway roundabout
- New fencing and cattle guards to control wildlife from entering the new corridor
- Frontage road connection to county roads
- Utility coordination
NDOT is delivering the project via the traditional design-bid-build method, with the design conducted by NDOT’s professional engineers and construction by Granite Construction. Construction started in January 2019 and is expected to be complete by fall 2020.
Construction Updates and Traffic Control
Since June, both directions of traffic on U.S. 50 have been shifted to use westbound lanes as NDOT widens the highway. In November, a new eastbound lane opened and eastbound traffic was shifted to a new eastbound outside lane. The lane switches take place from Roys Road in the Stagecoach area to the U.S. 95A junction in Silver Springs. Inside lanes will remain closed for construction, and access to and from U.S. 50 will be slightly modified to accommodate the new traffic configuration.
The speed limit will be reduced from 65 mph to 55 mph on U.S. 50 within the project limits for the foreseeable future during construction.
Fully-paved one-way frontage roads have been constructed on the outside of the U.S. 50/U.S. 95A intersection in Silver Springs. Motorists will drive the frontage roads in a counterclockwise direction, making right-hand turns to access roads and businesses in the same manner as a traffic roundabout. Speed limits will be reduced to 20 mph on the frontage roads.
The temporary detour is scheduled to be in place through the end of the year as a permanent roundabout is installed to replace the existing flashing traffic signal at the junction. The concrete roundabout will make intersection travel safer and quicker, with free right turns between U.S. 50 and southern U.S. 95 Alternate. Roundabouts can reduce fatal and serious injury crashes by up to 87%.
- Final design completed: fall 2018
- Construction start: beginning 2019
- Construction completion: fall 2020
Where Are We?
Crews have thus far excavated and paved approximately nine miles of new westbound lanes.
Through late 2019, construction work will focus on installing the new roundabout at U.S. 50 and U.S. 95A and paving the new eastbound lanes.
The U.S. 50 Phase 2 Widening Project is funded by federal and state funding. The estimated construction cost is $55 million.
