Truckee, CA…Westbound I-80 has been a problem for much of today. The first Sig Alert was issued just after noon today. There is currently another jack knifed big rig and additional trucks and vehicles having problems on I-80 near Hwy 20. Caltrans has issued another Sig Alert for I-80 as well. If you need to head westbound it looks like heading down SR-28 to US-50 may be your best bet. Be careful out there
