Woodstock will again offer a free shuttle bus from an offsite parking lot to downtown to relieve traffic congestion around Saturday evening’s Summer Concert Series performance at the Northside Hospital-Cherokee Amphitheater.

Four 24-passenger shuttle buses will run from 5 to 11:45 p.m. for the “Drivin N Cryin” concert, to start at 7:30 p.m. The shuttle will pick up concert-goers at the Northside Towne Lake Parking Deck, 900 Towne Lake Parkway, and drop off at the amphitheater at 101 Arnold Mill Road. The shuttle stop will be on East Main street in front of The Park at City Center.

The free Woodstock Trolley also will be operating downtown.
