I'm headed to a family get together Saturday in Rancho Cucamonga. What's my best route from the north end of the SART? I'm thinking Green River to Palisades to auto center. Then work my way over to rincon, Corydon, then river road which turns into archibald. I need to get to haven and foothill.

Try this TJ - it should get you part of the way there. I don't think you'd want to go all the way to the terminus of their ride but... it seems like the E-W roads up there are more pleasant.

There is always exit SART at Glassell north (turns into Kraemer) to Lambert west turns into Carbon Cyn. Right on Chino Hills parkway. Left on Peyton, turns into Riverside Drive to Archibald. Some climbing involved and CarbonCyn can be busy if not riding early morning.

If you want to go that way I'd take Tustin / Rose to Valencia and then to Lambert / Carbon Canyon. I hate riding on Kraemer but never have an issue with Tustin or Rose.

However you get to Archibald, take Archibald all the way to Foothill. It's probably your best bet as Miliken has all the Ontario Mills traffic and construction. Right before the airport hang a right on Jurupa and left on Haven. You can take Haven all the way to Foothill. Personally I would hang a left on Airport and get back on Archibald as it would be less congested than Haven. Haven has a lot of traffic around the 10 freeway. Archibald has a nicer flow w/ stoplights at the 10 freeway overpass. You can take either of those to Foothill.

Thanks for the help, looks like about 53 miles from Costa Mesa.
