There is great news for motorists heading to the lake for the Labor Day weekend. Gas prices have dropped to their lowest level for the holiday weekend since 2004, according to AAA.

The bad news is that road construction is still in position to thwart drivers.

“There are still many work zones around the state that will affect travel,” said Charlie Zelle, Minnesota Department of Transportation commissioner.

Statewide, law enforcement will be looking for drunken drivers in an enforcement campaign that runs through Monday.

For those staying in town, traffic-generating events include the final weekend of the Minnesota State Fair and the Renaissance Festival in Shakopee. The Lynx have home games Friday and Sunday at Target Center in downtown Minneapolis, and the Saints have baseball games Friday through Sunday at CHS Field in downtown St. Paul.

Metro Transit buses and light-rail trains will be on a Sunday/holiday schedule Monday. MVTA buses and the Metro Red Line will be on a holiday schedule Monday. No Northstar trains operate.
