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.

Did you know that there's a full Moon this Halloween? This won't happen again until 2039! This full Moon is called the Hunter's Moon. It is also a "Blue Moon", the 2nd full Moon of the month. It's also a Micromoon, the smallest full #Moon of 2020, since it's farthest away. #cawx

The new Echo Summit bridge looks similar to the old one, by design, but when viewed from below you’ll notice the new bridge is a single span and the old bridge, completed in 1939, had three spans. Work is wrapping up on the project this week!

#TrafficAlert: please watch for slow or stopped traffic on WB I-80 between Floriston and Hinton for bridge work. Concrete is still curing necessitating lane reductions.
