How will you welcome the new $6.4 billion Bay Bridge when it opens Labor Day weekend?

You don't have to choose just yet, but you do need to go to http://BayBridgeCelebration.com and sign up for email notifications so you'll know when registration opens, how to obtain passes for the bridge walk and the final schedule, including:

Bike -- Ride from Oakland City Hall into San Francisco in the afternoon on Sept. 1. Fee not yet set.

Dedicate -- Dignitaries, speeches and the like on the new bridge on Sept. 1, late afternoon or early evening, invitation only.

Fireworks -- Only partially funded at this point but organizers are optimistic. Watch from a variety of locations after dark on Sept. 1.

Run -- Half-marathon from Oakland City Hall to San Francisco City Hall starts about 7 a.m. A 12k from West Grand Avenue and Frontage Road in Oakland to San Francisco along the Embarcadero starts shortly thereafter. Both runs on Sept. 2. Fees not yet set.

Paddle -- Warm up with a six-mile paddle from Berkeley to the new bridge on Sept. 2. Stand-up paddle boards, kayaks and canoes all welcome. Fee not yet set.

Chains -- Traditional chain-cutting ceremony on Sept. 2 after runners leave and before first wave of walkers start.

Walk -- Stroll the full length of the Bay Bridge from Oakland into San Francisco starting around 8 a.m. on Sept. 2. It's free but participants need timed passes that allow them to board a shuttle bus at one of four Oakland BART stations.
