Photos: Closing in on Oracle OpenWorld

Cars line up at Howard Street in downtown San Francisco, which is closed for several blocks at Third Street to make way for Oracle OpenWorld. Traffic was lighter than usual at midmorning Friday, but a broader test of the impact could come at rush hour and during the morning commute on Monday.

San Francisco police were on hand Friday to alert motorists to the closure of Howard Street in downtown San Francisco. The duration of the closure, which runs for 10 days, is unprecedented in recent years, according to a city official.

As part of OpenWorld, Oracle is building a giant tent along Howard Street in Downtown San Francisco, resulting in the major thoroughfare being closed to motorists.

A partially finished banner is displayed outside the Moscone West Convention Center. Oracle has signs not only in all three wings of the convention hall, but also on cabs and at the nearby Sony Metreon mall.

The Oracle OpenWorld registration booths were full on Friday, not with convention-goers, but just with the workers being trained to do the the registration.

Workers sort out what goes where using a blueprint for the Oracle OpenWorld trade show, which kicks off Sunday. The massive show is filling up all three wings of the Moscone Convention Center, as well as a giant tent being erected on Howard Street in downtown San Francisco.
