ST. PAUL, Minn. - Normalcy tends to fall by the wayside when the Commander-in-Chief comes to town.

Just ask folks in the neighborhoods near St. Paul's Union Depot, where President Obama is scheduled to speak at 2 p.m. Wednesday, as part of his "Year of Action." Dozens of people were in line more than 4 hours before the scheduled appearance, to grab the best places in the house to hear the speech.

No Parking signs are also up on neighborhood streets where residents and customers of area businesses usually can leave their cars.

Mr. Obama will visit St. Paul's Metro Transit light rail hub before heading to the Union Depot. Police will barricade the streets to limit access and allow safe passage of the President's motorcade, which will have a major impact on local car and bus traffic. Metro Transit says a number of routes, including 262, 294, 350, 351, 361, 364, 53, 61, 63, 64, 70, 74 and 860. Changes are clearly spelled out on the Metro Transit website.

St. Paul Police will be tweeting about roads being closed down and barricades being put up on the department's Twitter account. Closures are expected to start about noon.
