Concertgoers bound for Cricket Wireless Amphitheatre in Chula Vista Wednesday night would be wise to get an early start.

Organizers of the sold-out Radiohead concert advise fans to expect heavy southbound traffic on Interstate 805 at Auto Park Drive, just west of the venue.

The parking lot opens at 4 p.m., with the concert scheduled to start at 7:30 p.m. Organizers suggest concertgoers carpool and head for the amphitheater early.

In May, traffic gridlock around Cricket caused many music fans to miss much of a Police reunion concert.
