If you have ever taken the drive through the city to the Golden Gate Bridge you have driven on an elevated freeway called Doyle Drive. It's been the road of choice for locals and tourists alike for the past 75 years.
But it has long since past the point of safe driving. Doyle Drive is often among the first places listed when it comes to roads that are unsafe in an earthquake.
Doyle Drive's days are now numbered.
Doyle Drive will be closed from 8 p.m. Friday to 5 a.m. Monday as construction crews begin to take down the old road and transfer traffic onto a new seismically safe bypass.

There will be no access to Highway 101 from Marina Boulevard or Lombard Street.
During the closure weekend, crews will use a fleet of 40 demolition hammers, now in transit from sites around the country. The hammers will crush the old bridge. The chipping away of Doyle Drive will continue for weeks after the closure, but it will begin with 24/7 demolition this weekend.
Traffic is expected to be a mess in the City. Drivers are asked to avoid the area and use alternate routes, including the Bay Bridge or the Richmond San Rafael Bridge.

There is a good animation that explains the changes at this link.
After the roadway reopens, motorists will travel on the completed bridge and tunnel and a temporary bypass roadway. The temporary driving condition will have five lanes managed by a moveable median barrier to accommodate shifts in traffic demand. Expect delays as motorists adjust to the new driving experience.
Below is a high res animation that takes you through the entire process, including a driver's-eye view.
