The Washington State Patrol is expecting a major traffic impact due to two events this weekend for Eastern Washington and the Idaho Panhandle.

Troopers said motorists should first expect delays all over Eastern Washington for the opening home game for Washington State University. They said fans from all over the state will be heading to Pullman and are expected to cause major back ups.

Then on Sunday, the Idaho Transportation Department will close down eastbound I-90 at the Washington-Idaho border due to a construction project. The closure will start Sunday night at 7:00 p.m. and last through 5:00 a.m. Monday morning. All traffic will be diverted to State Line Exit 299 at that time and drivers should see back-up from Liberty Lake to state line.

In order to delay with both traffic delays, Troopers will have all available units working this weekend.

Idaho law enforcement will be cracking down on aggressive driving for the next two weeks in their new statewide aggressive driving campaign.

The emphasis patrol starts on August 1st and goes through the 13th. “It is our goal to reduce the impact to our motoring public by encouraging everybody to slow down, back off, pay attention and be patient,” said Sgt. Erik Turrell with the Coeur d'Alene Police Department's CARE Team.

The patrol is sponsored by the Idaho Department of Transportation and the Office of Highway Operations and Safety. Kootenai county deputies will be conducting the patrol at various locations around the county. They will focus on aggressive drivers who speed, tailgate, fail to yield and cut in and out of traffic.
