The city will hold a Labor Day Kick-Off Celebration at its new McGrath Amphitheatre on Friday, Aug. 30, and three local bands will perform for free on that day to celebrate the venues opening on the riverfront across from downtown.

Shortcut to Nowhere will perform from 3:30 to 4:30 p.m., Helforstout will play from 5 to 6 p.m. and Super Size Seven from 6:30 to 7:30 p.m.

The amphitheatre is designed to be connected to a Festival Grounds park area along Diagonal Drive SW, and this week the City Council approved plans to construct a 14-foot-wide trail from the amphitheatre along the riverfront to the Festival Grounds.

Work on the trail is expected to cost $140,000, will begin in October and be complete by May 20, 2014, the city reported.
