Folks planning on driving through downtown Long Beach this weekend may need to rethink their routes.

From 5 a.m. Saturday, Aug. 17 to 5 a.m. Sunday, Aug. 18, Shoreline Drive will be closed between Ocean Boulevard and Shoreline Village Drive.

The gate arm at the end of Linden Avenue at Rainbow Harbor and Shoreline Marina will also be closed.

The closures will make way for a special event coming to the Marina Green. At 2 p.m. Saturday, Insomniac: The Alchemy Tour – featuring the bands NGHTMRE + SLANDER, Seven Lions and The Glitch Mob – will begin.

Parking in the area is also expected to fill up.

City officials encourage visitors to park north of Ocean Boulevard, to use public transportation and to use ride-sharing services.

Electronic message boards will direct festival-goers to available downtown parking lots.
