San Diego County officials are examining an elaborate addition to the Coronado Bay Bridge — a two-mile bike and pedestrian path suspended underneath the bridge.  

“I think it would be something that people would come to want to ride, like going to the St. Louis Arch or the Seattle Space Needle,” said local architect Lew Dominy.

Dominy said the gigantic steel tube would cost roughly $50 million and be a part of the county’s Bayshore Bikeway. The bikeway is already 60 percent finished, and when completed, it would be a continuous pathway around the southern part of San Diego Bay. The bridge tube would be a huge addition…

The architect is confident it can be done, and he hopes San Diegans will one day be able to pedal underneath their iconic bridge.

“Because you’re 200 feet up in the air and it is spectacular,” said Dominy.

Dominy estimated the tube would take two years to build if it is ever approved.

As state lawmakers contemplate an independent inspection of the new Bay Bridge tower foundation, construction crews are beginning what might be called the Big Lift — a major step in building the $6.3 billion east span, scheduled to open by Labor Day 2013.

Workers on Tuesday began the three-month process of lifting the 35,200-ton bridge decks from the temporary steel trestles on which they were assembled onto the tower and main suspension cable that will cradle and support the suspension span. As they started work, a state Senate committee grilled Caltrans over media allegations of irregularities in concrete inspections for the tower’s foundations…
