The official opening date for the long-contested East Palo Alto Ikea has been set and officials are gearing up for the traffic jams. With a prime Highway 101 location the shiny new blue store will likely snarl peninsula traffic in a wide radius. It is also near the Dumbarton Bridge, which spans the bay to Fremont. Opening day is a Wednesday, August 27th and there’s a Labor Day long weekend’s worth of cheap, fun-to-pronounce home improvement acquisition immediately following. Take alternate routes.
