Portland officials are advising city drivers that a section of Park Avenue will be closed to traffic on Thursday afternoon while President Obama attends a political rally.

Park Avenue is scheduled to be closed to vehicles between Deering Avenue and St. John Street from 3 to 8 p.m. Foot traffic may be restricted at times, as well.

Obama is headlining a rally at the Portland Exposition Building in support of U.S. Rep. Mike Michaud’s gubernatorial campaign. Michaud, a Democrat, is locked in a tight battle for the Blaine House against Republican Gov. Paul LePage, with independent Eliot Cutler trailing well behind in third place, according to recent polls. Former Maine Sen. George Mitchell, a Democrat who served as U.S. Senate Majority Leader, is also expected to attend.

City officials urged those with tickets to park elsewhere and walk to the Expo building.
