SR-28 Shared Use Path, Lake Tahoe

Press Enter to show all options, press Tab go to next option

traffic3Nevada State Route 28 south of Lakeshore Drive, in Incline Village on Lake Tahoe's east shore, parallels 11 miles of undeveloped shoreline, the lake's longest stretch. The two-lane, mountainside road is also the only access route for over one million recreationists and 2.6 million-plus vehicles per year. Use along the corridor continues to grow, with shoulder-parking projected to double in the next 20 years.

The conditions are challenging for motorists and the nearly 2,000 pedestrians and bicyclists using travel lanes during peak times. Additionally, associated erosion impacts the lake's water quality. In response, 13 agencies, led by the Tahoe Transportation District (TTD), came together to find solutions and develop the recommendations in the SR 28 National Scenic Byway Corridor Management Plan.

In an effort to coordinate safety and mobility, the group worked to develop the Nevada Stateline-to-Stateline Bikeway North Demonstration Project Joint Environmental Assessmentfor the first three miles of shared-use path from Incline Village to Sand Harbor. This is a component of the larger Nevada Stateline to Stateline Feasibility Study Report for the entire 30+ miles of shared-use path, also known as the Tahoe East Shore Trail. The proposed project is a Tahoe Regional Planning Agency (TRPA) Environmental Improvement Program project.

Traffic Control Information Spider Excavator - Bridge Foundation Construction near Sand Harbor2

During the 2018 construction season, expect 20-30 minute delays with the majority of the work done Sunday night through Friday afternoon. Traffic control measures will include shoulder closures, lane closures, and one-lane flagger controlled closures. Additional construction-related closures and tips include:

  • Short-duration full road closures may take place in the fall for construction of pedestrian bridges. Advance notice will be provided so motorists can plan accordingly.
  • The Memorial Point roadside parking lot and restroom will continue to be closed for construction staging.
  • Beach and trail access between Lakeshore Boulevard and Sand Harbor State Park may be closed during construction. For traveler’ safety access to beaches or trails is not allowed through the construction zones.
  • Roadside parking from Ponderosa Ranch Road to approximately three-plus miles south of Sand Harbor State Park will not be allowed during construction. Travelers should pay special attention to no parking/tow-away zones throughout the project area as towing will be enforced in no parking zones.
  • With potential travel delays, vehicle owners are encouraged to be aware of vehicle fuel and/or electric charge range and utilize available fueling/charging stations before traveling through road work zones.
  • Tow Away Zone: Vehicles illegally parked on the side of the road through the work zone will be towed.
  • No access to new shared use path or shared use path parking lots will be available until completion of construction in 2018/2019.

  • Environmental process completed - 2016
  • Final Design completed - early 2017
  • Construction - 2016 - Spring 2019 (completion weather-dependent) 

Construction During the 2018 Season

This season, NDOT will complete the remaining paved sections of the shared use path and continue the construction of the six pedestrian bridges.

Additionally, drainage work south of Sand Harbor will be completed, including added work proposed by The Incline Village General Improvement District. NDOT also anticipates completing the majority of drainage work and installation of Intelligent Transportation Systems north of Sand Harbor. 

Phase 2 Construction, Spring 2017

During the 2017 construction season NDOT and contractors:

  • Built the structural components of the 10-foot-wide, paved shared use path from the south end of Incline Village to Sand Harbor including:
    • soil nailed walls
    • retaining walls
    • bridge foundations
  • Highway stormwater collection facilities, guardrail improvements, emergency pullouts
  • Trenching and placing conduit for future fiber optics and IT technology

Construction Progress In 2016 Soil Nail Walls north of Sand Harbor - 2017

Several milestones were achieved during the 2016 season.

Two nodes of parking and a transit stop at Ponderosa Ranch were constructed, including concrete curbs, gutters, walkways and the EPIC water quality system. A third parking node is in progress, along with visitor amenities such as bike racks and information kiosks.

Construction of the tunnel to Hidden Beach was completed on October 20. The tunnel was built with a series of precast concrete boxes, approximately 14 feet wide by 10 feet high, which span 73 feet under the highway. Granite Construction placed 8'x15' steel plates on the uphill side, back-filled that area, closed the west side of the tunnel for safety, and completed stabilization and erosion control work. This is in preparation for staging of equipment to build the tunnel wing walls and the trail to the tunnel starting next spring.

NDOT is using the Construction Manager at Risk (CMAR) process to deliver the project. This process is used in unique environments like Lake Tahoe, where there are a number of construction challenges such as steep terrain, limited access and environmentally sensitive areas. The department has brought the construction contractor on to work side by side with the engineers in the final design.

Project Benefits

shared useAlthough each of the project’s major components may provide high value as independent construction projects, the project partners determined that the highest return value for motorists, pedestrians and bicyclists will be achieved when there is connectivity of the facilities, which in turn will provide the biggest improvement to the environment

The project takes an integrated approach with each of the major components contributing to solutions for the multitude of challenges, two of which are pictured, in the SR 28 corridor:

  • emergency pull outShared-use path for recreation access
    • safer transportation choices and improved experience
  • New or expanded off-highway parking
    • fewer accidents, safer access and connectivity to recreation destinations
    • reduced erosion and fine sediment run-off, protecting lake water quality
  • Maintenance and emergency pullouts
    • safe locations for corridor operations
    • improved circulation
  • East Shore Express transit upgrades
    • improved highway safety and circulation
    • easier access to recreation destinations
