Caltrans has over a thousand cameras monitoring freeway sections across California and Interstate 80.  On top of that, NV Roads provides camera feeds for both Mt. Rose Highway and Interstate 80 as it stretches into Nevada. These live feeds and pictures are made available so commuters can make informed decisions as to when to take a trip on the freeway.  Caltrans and NV Road cameras are sometimes not available due to limited computer bandwidth, heavy use, or due to servicing, so please be patient for the video to appear.   If video does not appear within 20-30 seconds, then it is likely that camera is temporarily out of service. You can also check CA highway conditions and closures by calling (800) 427-7623 and NV highway conditions and closures by calling (877) 687-6237.
