https://www.ttnews.com/articles/nevada-dot-construction-project-involves-large-truck-restrictions The Nevada Department of Transportation recently announced commercial truck restrictions on a Lake Tahoe-area highway as the agency undertakes a construction project. Truck restrictions and roadway shoulder closures were scheduled to begin on state Route 431, also known as Mount Rose Highway, on May 3. SR 431 runs from Interstate 580 outside Reno to Incline Village, which is situated on the northern side of Lake Tahoe near the state's border with California. According to NDOT, commercial truck through traffic equipped with air brakes will be prohibited from traveling westbound via SR 431 farther than the Mt. Rose Ski Tahoe resort. These restrictions are in place through the fall. Trucks traveling eastbound from Incline Village to Reno will be permitted. The closure is a safety precaution that was put in place to avoid the issue of trucks traveling down the mountain and potentially experiencing brake trouble in the work zone. Air brakes are typically used for large-truck configurations, which can sometimes experience brake failure in mountain corridors. "Heavier weights run the risk of brakes overheating and the runaway truck ramps won't be accessible during this highway construction project," Nevada Highway Patrol Trooper Hannah DeGoey told Transport Topics. "A pickup truck with hydraulic brakes, for example, needing to utilize the use of a runaway truck ramp is unlikely." As an alternate corridor, NDOT spokeswoman Meg Ragonese said routes such as U.S. 50, which winds around the southeastern side of Lake Tahoe, are primarily used for truck traffic entering the Lake Tahoe Basin in Nevada. A major east-west route, U.S. 50 stretches from Sacramento, Calif., to the Maryland coast. The truck restrictions are in place because of NDOT's two-year project to repave and enhance state Routes 431 and 28, which wraps around the northern shore of Lake Tahoe. On SR 431, three inches of asphalt will be removed and replaced. The aging roadside concrete barrier rail will be upgraded on multiple segments of the corridor, and certain roadway shoulders will be reconstructed and flattened. Improvements to SR 28 will also include replacing asphalt and improving sections of guardrail. Draining improvements will be made to ensure additional stormwater treatment before reaching Lake Tahoe. Near Memorial Point Scenic Overlook, an aging timber retaining wall will be reinforced with a soil nail wall. The process of soil nailing uses steel elements, or nails, to stabilize slopes. NDOT advised that, over the next two years, drivers should anticipate shoulder closures and single lane restrictions on these routes as the agency works on about 15 miles of roadway. The construction work is meant to restore the mountainous highway surfaces, which can deteriorate under freeze-thaw conditions. According to NDOT, these highways were last fully reconstructed about 14 years ago. "State Routes 28 and 431 are the primary highway connections to northern Lake Tahoe," Ragonese told TT. "The road improvements will enhance these vital Tahoe highways for the 10,000 drivers who travel the roadways each day. The highway improvements will also enhance roadside drainage and infrastructure to further preserve water quality of Lake Tahoe." _____________________________________________________________ Q&A deadline: 04/08/2020 11:00 AM County(s): Washoe Mount Rose Highway (State Route 431/ SR 431) is recognized as the highest continuous pass in the Sierra, reaching an elevation of 8,911 feet. Designated as a scenic byway, State Route 431 is officially named Highway to the Sky. Mount Rose Highway connects Lake Tahoe to the City of Reno, starting at the junction of State Route 28 and stretching twenty-four (24) miles northeast to the South Virginia Street intersection. From the foothills approaching Reno, the two-lane highway increases to a four-lane highway with a center two-way left-turn lane (TWLTL). The functional classification of SR 431 transitions from a Rural Minor Arterial to an Urban Principle Arterial- Other. West of Interstate 580 Interchange, SR 431 connects to South Virginia and the Veterans Parkway roundabout via Geiger Grade Highway (State Route 341/ SR 341). As nearby development growth in the valley increases, the need to prepare a corridor plan becomes increasingly important. The Nevada Department of Transportation (DEPARTMENT) desires to perform a corridor study of the Mount Rose Highway (State Route 431/ SR 431). The intention of the study is to develop a Mount Rose Corridor Action Plan, providing decision makers with a guide that will define future transportation needs along the SR 431, reduce traffic delay, provide feasible solutions, and improve safety. The Plan will provide participating agencies with workable and cost-effective transportation enhancements that address interim and long-term needs. The improvements will be assessed for socioeconomic, community, environmental, and monetary impacts of implementing a range of needed projects addressing existing and projected transportation problems. The work consists of the analysis and evaluation of the corridor, access management, community development and future growth, and safety improvements to the Mount Rose Highway and local roadways within the specified corridor, prioritizing feasible and affordable improvements to maximize safety, accommodate future growth and mobility of the traveling public- to include all modes of transportation, and developing conceptual designs within the study area. Goals of the Project: 1. To develop a corridor plan for the corridor with the participation and support of the DEPARTMENTs partnering agencies (Washoe County, City of Reno, and the Regional Transportation Commission of Washoe County [RTC Washoe]) and the public. 2. To assist the DEPARTMENT with compiling all relevant existing studies, policies, and plans. 3. To review and interpret historical crashes along the corridor, include public complaints, and provide safety strategies. 4. Evaluate existing community development plans and future trends and identify the necessary access management to meet the communitys future needs. Based on county and city land use patterns, provide improvement recommendations to enhance intercity mobility. 5. To provide a 20-year forecast for the corridor, matching RTC Washoes future horizon year, including planned roadway network, projected traffic volumes, and anticipated operations if no improvements are made. 6. To prepare a corridor plan that defines transportation needs and prioritizes design alternatives to improve connectivity and identify policies, programs, schedules, responsibilities, and funding sources needed to ensure the corridor services the future travel needs in the interim (within five [5] years) and long-term time frames.
