The bike-riding extravaganza known as CicLAvia drew tens of thousands of cyclists on a route that stretched from downtown L.A. to Venice.
The event drew many cheers. But there were also some jeers from motorists trying to get around.
Numerous streets were closed, and that led to heavy delays, especially in downtown L.A. where several streets were subject to long backups.
Some motorists vented on social media.
“I get it LA trying to promote riding your bikes..but seriously?” one man wrote on Twitter. “This is the worst traffic I have dealt with!”
Another added: “I hate LA for this... Been in traffic for a 1Hr”
So many cyclists turned out that there were some bike traffic jams as well.
Times reporter Adolfo Flores captured this one:

In all, 15 miles of roadways were closed for the event. They are expected to start opening later this afternoon.
