Work to fully extend the bike and pedestrian path along the eastern span of the Bay Bridge from Oakland to Yerba Buena Island is back underway.

After a set of delays, the project is now slated to be completed this September, Caltrans spokeswoman Leah Robinson-Leach says.

"The public has been patient," said Robinson-Leach. "They have waited for this. And there's so many cyclists looking forward to have that entire bike path for a full experience to get to the island, as well as come back to Oakland."

The delays came during Caltrans crews' ongoing demolition of the old eastern span and as the agency changed its design plan for the bike path extension to Yerba Buena Island.

Currently, the Bay Bridge Trail, the official name of the bike path, starts in Oakland but stops adjacent to the eastern span's suspension tower. Initially, Caltrans said it would complete the path by the fall of 2014.
