Fans heading to this weekend's Lowertown Blues and Funk Fest in St. Paul's Mears Park might not be the only ones singing the blues. Drivers on Hwy. 61 in Cottage Grove where a bridge project has the potential to spawn big backups might be, too.

On the sports scene, the Twins and Saints are home for weekend series. The Loons play Saturday afternoon at TCF Bank Stadium. Look for closures along the routes of the Selby-Mackubin and Sprint Bike races and Lake Street and Minnehaha Avenue for Sunday's Open Streets in Minneapolis.
