How much time on average does it take to get from SF to Sacramento and what is the best option?
There is a conference in Sacramento on Tuesday at 6:00 PM, What time should I leave SF to avoid traffic?
On average it takes anywhere from 2-3 hours. I would leave around noon just to make sure you're there at a comfortable time before your conference.
I would take the 80, it's the quickest way. You might even get there in a hour and half if there's no traffic!
In order to make it to the conference by 6pm and miss traffic, you should leave from SF by around 2pm, no later than 3pm. It also depends where in SF you're coming from and where exactly in Sacramento the conference is, but the traffic on the 80 freeway can get really bad coming out of SF around the bridges and everything, so if you leave between 2-3pm you should get there in a good amount of time while minimizing the traffic you hit.
Driving is the best option.
Without traffic takes 70 - 80 minutes. Buffer an additional 30 - 45 minutes for traffic, leaving around 3:45p is a safe bet.
Traffic time really depends on where in Sacramento you're going, in addition to anything that could happen on the road.
If you're looking to make it to Sacramento (city center) by 6:00 on Tuesday, I suggest leaving SF no later than 2pm. What is normally a 2.5 hour drive can easily turn into 4pm in the summer (Tahoe traffic) or with a single accident.
Depending on traffic, give it 2 to 2:30 min via HighWay 80
1 hour and 42 min from San Francisco to Sacramento via I-80 E
3:30 to be safe, but normally takes about 1.5 hrs
Give yourself two hours given it will be rush hour
All depends on traffic - could take 90 minutes or four hours! Consider taking BART to Amtrak to Sacramento. Use Uber if your convention is far from downtown, otherwise it's an easily walkable city.
If you drive listen for radio updates and seek alternative routes outta the Bay Area. But after that, 80 is really your only option to get into Sacramento. Enjoy the visit!
