"Approximately 300 riders participated with a motorcycle escort from the Oakland Police Department," Katz reports.
"The CHP patrolled the bike path on the bridge. Several CHP officers were mounted on bikes and they will be permanently doing so — as is the case on the Golden Gate Bridge's bicycle/pedestrian causeway.
"A CHP source said that 1100 people rode the pathway.
"I saw one Penny Farthing, two unicycles, one recumbent bike and several art bikes, including one that incorporated parts from a vintage Buick.
"In addition, scores of people made the long trek on foot.
"Access to the Alexander Zuckerman path is from Shellmound Street in Emeryville and Maritime Street in Oakland.
"For opening night, the path stayed open well after dark. Hours henceforth will be dawn until dusk until the path is extended to Yerba Buena Island which will take place supposedly in 2015."
Here are some glimpses of the ride and of scenes that most drivers will miss. All photos by Ken Katz.
Katz notes that the path is named for the late Oakland city planner and longtime bicycle advocate Alexander Zuckermann, who lived just off Lakeshore Avenue.
