The Nevada Department of Transportation is reconstructing the Kingsbury Grade State Route 207 from the junction at Highway 50 to the summit just east of Tramway Drive. The grade will be closed to through traffic near the summit 24/7 after Labor Day to October, but businesses and residences will be accessible by detouring to Kingsbury Grade via U.S. 50 in Tahoe. Nighttime work will take place during the summer months of June, July and August, with flagger and other construction-related travel delays to be expected. For more information on NDOT's project, go to


Water-Quality Improvement Project Nearly Complete on U.S. Highway 50 
SOUTH LAKE TAHOE – This $43.1 project to collect and treat stormwater runoff and provide substantial safety and beautification features is in its final season of construction, which started in 2011.

The project is located within the city of South Lake Tahoe on U.S. Highway 50 from Trout Creek Bridge to Ski Run Boulevard.

The project will collect and treat storm water runoff as part of the Lake Tahoe Environmental Improvement Program (EIP). It will also widen the roadway to provide 6 feet shoulders for bike lanes, improved the roadway cross slope, replace traffic signals, and provide Americans with Disabilities Act (ADA) compliant sidewalks, pedestrian lighting and landscaping.

The project is in its final phase of construction and is expected to be completed in July 2013.

Work Continues on Highway 89 From Tahoma to Tahoe City  

TAHOE CITY – Work will continue this summer on a multi-year project along Highway 89 between Tahoma and Tahoe City.

The $34 million federally funded project will rehabilitate stormwater drainage and treatment systems, realign the road, and widen shoulders to allow for bicycles and places for cars to pull out of traffic.

The project will improve driver visibility, traffic safety, install runoff collection and treatment, add curb and gutters and move the existing bike trail.

In Phase 1 of the project this summer, a Caltrans contractor will install nine sand vaults for stormwater treatment between the Placer County line and Madden Creek. All work will take place at night. No other Caltrans roadwork is anticipated this summer. Roadwork will take place in 2014, 2015 and 2016.

Southwest Gas contractors will also be working on the highway this summer as they continue to relocate gas lines. The utility relocation is required before Caltrans’ roadwork.  Southwest Gas expects to complete two phases of its work this summer, from Pine Street to Timerbland Drive.

Motorists can expect traffic delays of up to 20 minutes through the construction zone. 

Moving Forward with Another Water-Quality Improvement Project on U.S. Highway 50

SOUTH LAKE TAHOE – A $7.3 million road improvement project will begin May 1, 2013, on a half-mile section of U.S. Highway 50 in South Lake Tahoe.

The project on Highway 50 from 1,200 feet west of Ski Run Boulevard to Wildwood Avenue will allow for the collection and treatment of stormwater runoff, in addition to adding Class II bike lanes, Americans with Disabilities Act compliant sidewalks and pedestrian lighting. Other features include a new intersection signal, landscaping and streetscaping. Shoulders will also be widened to six feet.

The primary contractor on this project is Granite Construction of Sparks, Nevada. Construction will occur primarily from the hours of 6 a.m. to 6 p.m., Monday through Friday, from May 1 through June 30 and 8 p.m. to 11 a.m., Monday through Friday, beginning July 1. Roadside message boards will be used to post the latest information.   

The project’s target completion date is by the end of 2013 construction season. There may be some traffic delays where lanes are reduced. Motorists, bicyclists and pedestrians are asked to be patient and allow a few extra minutes to get through the work zone. 

Water-Quality Improvement Project Set to Begin from Airport to 'Y'

SOUTH LAKE TAHOE – Construction is scheduled to begin in May 2013 on this $12.5 million water-quality improvement project located within the city of South Lake Tahoe on U.S. Highway 50 between the Lake Tahoe Airport and the “Y.” 

The first mile of the project is a two-lane conventional highway. The remaining 0.7 of a mile is a four-lane conventional highway with a continuous two-way left turn lane. 

The project will collect and treat stormwater runoff as part of the Lake Tahoe Environmental Improvement Program (EIP).  It will also widen the roadway in the two-lane section to provide 3- to 4-foot shoulders for bikes and will provide curb, gutter and sidewalks in the four-lane section.  Areas with meandering walkways will be overlaid. 

The project’s target completion date is by the end of the 2013 construction season.


SR 89 West Shore Project
Caltrans will be constructing a new drainage system and rehabilitating the existing system to collect runoff for stormwater treatment. The proposed project is on Route 89 in El Dorado and Placer Counties, at and near Tahoe City, from 0.2 mile south of the El Dorado/Placer County Line to Fanny Bridge. 

Traffic restrictions are in place on SR 89 from Tahoe City to Tahoma  Please expect up to a 10 minute delay for one-way traffic controls. Utility work is taking place.

SR 89 Repavement Project
(From West River Road to Squaw Valley Road) 

Caltrans recently completed the shoulder-to-shoulder repave project along Highway 89. For more information on the project, please read the announcement press release here:

Trout Creek Bridge to Ski Run Boulevard 
Caltrans is doing major construction on U.S. Highway 50 in South Lake Tahoe from Trout Creek Bridge to Ski Run Boulevard to add a storm drainage system to help protect Lake water quality, class II bike lanes, ADA-compliant sidewalks and pedestrian lighting.

Placer County Homewood Water-Quality Project 

This project was designed by the Tahoe Engineering Division of the Department of Public Works. The project includes storm water improvements required of Placer County by the TMDL regulations promulgated by the Lahontan Regional Water Quality Control Board and additional water quality improvement required by the TRPA. 

Improvements were designed to be as low-key and non-obtrusive as possible to sit quietly in the rural-type neighborhood. Street construction will not be upgraded; this is a water quality improvement project. 

Construction begins July 25, 2012. It is anticipated construction will be complete by October 15, 2012. The project area generally includes the neighborhood streets between Cherry and Silver, north of the Homewood Mountain Resort Lodget. No streets will be closed during construction. Placer County will move as swiftly as possible to complete the project and requests resident patience.

Plan set copies are available to look at in the Tahoe Engineering Division offices in Kings Beach.
