Many drivers get frustrated by major freeway projects that slow their commutes, even though most drivers end up enjoying the finished products.

KTVU surveyed the progress of the Bay Area's 10 biggest regional road projects.

The 10th biggest project in the San Francisco Bay Area is in the North Bay along Highway 101. Caltrans is adding a $118 million car-pool lane in Sonoma County, which should be done by 2013.

The ninth on the list is the Nimitz Freeway, where Caltrans is building an earthquake-safe overpass across Fifth Street in Oakland. The $130 million project should be finished by next year, officials said.

The eighth largest freeway project is a car-pool lane for Interstate 580 through the Livermore Valley which is expected to cost $130 million. Completion for that project is scheduled for 2014.

At number seven is widening Highway 12 between I-80 and Napa for $136 million. It is supposed to be done by 2015, Caltrans officials said.

"There's a lot going on," said Caltrans spokesman Bob Haus. "This really is going to be an exciting time for us."

The sixth biggest freeway project in the Bay Area is the Highway 4 widening project budgeted at $337 million. It's scheduled to be completed by 2014.

At number five is the fourth bore of the Caldecott Tunnel. It's expected to cost $391 million and will be finished next year.

Devil's Slide, on the San Mateo coast, is going to cost $439 million. The project will finally be finished later this year, which is behind schedule.

Haus said encountering hard rock and then soft rock and then hard rock slowed the project. "Every time we did that we had to change out all the equipment so that set us a bit behind," Haus added.

In the North Bay, the third largest project is the widening of Highway 101 between Novato and Petaluma. That project should cost $745 million and will get completely underway by 2016. Caltrans said there is no solid target date for completion.

The second biggest Bay Area road project is Doyle Drive which just underwent a massive demolition. It will cost a little more than $1 billion and should be totally complete by 2015, according to Caltrans.

The biggest and most controversial project by far is the Bay Bridge. The project will cost $7.2 billion. Caltrans said it's finally worked out all its internationally noted problems and will have it open on Labor Day 2013.
