The weekend traffic volume on metro area freeways and highways is likely to be heavier than normal as thousands make their way to the Minnesota State Fair. Drivers can expect traffic snarls on Snelling, Larpenteur and Como avenues along with other roads in the vicinity of the fairgrounds.

The fair will bring a surge in traffic on Hwys. 280 and 36 and on Interstates 35W and I-94, too. Ramp jams along those routes are possible as drivers get off the mainline. One spot where traffic typically backs up are on I-94 at the Huron Boulevard exits as many drivers head to fair park and ride lot at the University of Minnesota. There also will be lots of buses on the roads as Metro Transit, SouthWest Transit and Minnesota Valley Transit Authority operate their State Fair express service.

Downtown Minneapolis will see an influx of vehicular and pedestrian traffic on Sunday as the Vikings kick off the U.S. Bank Stadium era with their pre-season home opener against San Diego at noon. The game will put pressure on downtown streets. The one-block closure of Chicago Avenue between 8th and 9th Streets and westbound Washington Avenue from Portland Avenue to Hennepin Avenue could complicate the traffic flow.

The Lynx get back to action after the Olympic break with a 6 p.m. game Sunday at Target Center. The Renaissance Festival continues in Shakopee.

The most noteworthy road closure in the metro is on Hwy. 5, also known as W. 7th Street. It will be closed from 10 p.m. Friday night through Monday morning between Hwy. 55 and Davern Street.

Vacationers making a jailbreak for the cabin will find I-94 down to a single lane between Hwy. 23 and Collegeville, but two eastbound lanes will be available between 11 a.m. and 8 p.m. Sunday. To the north, it's single lane all weekend on I-35 between Hinckley and Pine City.

A DWI enforcement continues through Labor Day, so drive sober.
