on I-80 of potential hazards and road closures has been the impetus for NDOT to develop important internal processes that involve two NDOT districts, state law enforcement, media, local agencies (including cities and law enforcement) , and key freight stakeholders.

Truck traffic can receive these alerts and notifications several ways: NDOT DMS and highway advisory radio, DOT flashing beacons (warning that state line is closed) , 511 and NDOT's traveler information web page, commercial broadcast media, and truck stop announcements and notices.

As conditions warrant and if the closure duration is extended, NDOT will initiate additional operational procedures, including posting messages on DMS further east on I-80, activating additional flashers, andupdating the information going to 511 and NDOT's website. NDOT District 3 also is notified to begin alerting trucks as they cross into Nevada on I-80 from Utah; a longer closure would also necessitate notifying Utah DOT and Wyoming DOT of the westbound I-80 closure at the Nevada/California state line, and these states would also initiate notifications using their respective systems and infrastructure.

In some instances, law enforcement will initiate its own processes to implement truck turnarounds further east on I-80, thereby restricting trucks before they reach the Reno area. Types of Agencies Involved Primary partners for initiating and implementing winter response strategies on this segment of I-80 are Caltrans and Nevada DOT District 2 and, depending on the duration of theclosure, NDOT District 3, further east on I-80, also will have a critical role.

From page 59... ...
Recognizing the importance of providing advance notification, particularly to freight, has been the motivation for NDOT to plan and program specific enhancements and infrastructure. Corridor information needs along I-80 have resulted in NDOT Districts 2 and 3 installing permanent DMS and highway advisory radio on westbound I-80, with an increased number of flashing beacons that are activated during state line closures on the segment of I-80 in District 2 approaching the Reno metropolitan area.

From page 60... ...
This has translated into deploying traveler information infrastructure further east of the state line, coordinating with local agencies and truck stops about the closure and its potential impacts, and establishing lines of communication with neighboring states to provide even more advance warning to freight traffic. A long-standing agreement between Caltrans and NDOT established the initial framework for cooperative management strategies and gave Caltrans the ability to implement checkpoints and truck-turnaround points in Nevada.
