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
Fanny Bridge
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.
89/50 “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).
