BRAINERD -- If you're heading up Highway 371 through Brainerd this weekend, be prepared for major delays.

The Minnesota Department of Transportation says more than 100-thousand people will be attending the 30th annual Lucas Oil National Hot Rod Association Nationals at the Brainerd International Raceway.

You should expect heavy traffic volumes, delays and sudden stops tomorrow through Sunday.

Road construction on Highway 371 will be halted south of B.I.R. but will continue north of the raceway up to Pequot Lakes. You're advised to find an alternate route if possible.
