Why the Roadwork?

Did you know the roadwork happening around Lake Tahoe isn’t just for the roads? Caltrans is building new storm drain systems to protect water quality. The new drainage systems will capture stormwater runoff and filter out dirt, oil and litter before it gets to the lake.

Some traffic delays are unavoidable so please allow some extra time. It’s a small price to pay to protect Lake Tahoe for decades to come.

Current Projects
Highway 89 Lakeside
Caltrans is constructing a new drainage system and rehabilitating the existing system to collect runoff for stormwater treatment. The project is on Highway 89 in El Dorado and Placer Counties, from 0.2 mile south of the El Dorado/Placer County Line to just south of the Truckee River “Fanny” Bridge.
Highway 89 Realignment/Fanny Bridge Replacement (Caltrans Partner)
State Route 89 (Placer County): This project in Tahoe City includes building a new Truckee River bridge east of the Caltrans Maintenance Yard with roundabouts on either end, replacing the existing Truckee River “Fanny” Bridge, constructing a roundabout at the “Wye” intersection and making complete street enhancements to the portion of Highway 89/West Lake Boulevard that will become a county road after project completion, which is expected in 2018.
U.S. Highway 50 "Y" to the Trout Creek Bridge
This project will collect and treat stormwater runoff as part of the Lake Tahoe Environmental Improvement Program (EIP). It will also widen the roadway to provide 6-foot shoulders for bike lanes, replace traffic signals, replace curb, gutter and sidewalks, and improve pavement cross slope. Caltrans is working with the City of South Lake Tahoe to incorporate improvements at Sierra Boulevard. (signal and left turn lane).
Upcoming Projects
Meyers Intersection
The purpose of this project is to improve safety by reducing the number and/or severity of collisions at the intersection. This project proposes to convert the existing T intersection at U.S. Highway 50 and State Route 89 in Meyers into a three-leg roundabout. The existing intersection configuration has State Route 89 under stopped control and Highway 50 uncontrolled.
Echo Summit Bridge Replacement
The project will replace the Echo Summit Bridge which is located in El Dorado County 7 miles west of the city of South Lake Tahoe along U.S. Highway 50 near Echo Summit. At the project location, the road width is very narrow and confined by a vertical rock cut slope on the mountain side and a nearly vertical downward slope on the Basin side.
