Bradford Ridge Trail vs Bowen Ranch travel time from LA area

Has anyone ever timed the difference between accessing the springs from Bradford Ridge vs Bowen Ranch when coming up from the LA area (Long Beach to be specific)? I know the hike to the springs is longer from Bradford Ridge but what I am looking for is the overall difference between driving up to the Bradford Ridge trailhead and hiking in vs going thru Hesperia then the long drive up Bowen Ranch road and hiking in. I have never driven the road up to Bradford Ridge so I am just curious if I would have less travel time going in via that route and have more time at the springs. I have been wanting to try this route but if it takes longer to get to the springs I will stick with the Bowen Ranch route.
