Kentucky State Police are again providing traffic updates through social media and a mobile app for NASCAR fans heading to Kentucky Speedway for the Xfinity and Sprint Cup series this weekend.

State police said in a news release that motorists can download the free KSP mobile app by searching "KSPOLICE." Also, state police will use Twitter and roadside message boards to provide traffic and parking updates. The Twitter handle is @KYStatePolice .

Police say commercial traffic and anyone else not heading to the speedway should avoid the Gallatin County area, specifically Interstate 71, on Saturday and Sunday. Commercial vehicles traveling between Louisville and Cincinnati should use Interstate 64 and Interstate 75, detouring through Lexington.
