The 505 Freeway stretches in a north south direction for 33 straight fast miles from the 80 at Vacaville in the south to just south of Dunnigan where it connects to the 5 heading north. It's a quick short cut to get from the Bay Area to the north Sacramento Valley. Parts are concrete and parts are asphalt, but it all fast with a 70 MPH speed limit. Which means basically you can do 75mph and not get a ticket. I've seen very few CHP out on this stretch of road so you can probably get away with even faster ..... but you gas mileage will go way down if you do over 75.
Not many services for these 33 miles so make sure you have gas and can wait till you get to Dunnigan on the 5 or Vacaville on the south end to eat or pee. I like this road basically cause I can really haul ass and still be safe as the traffic is generally light. read more
