Stoneridge Drive Extension Open
Another option between Pleasanton & Livermore, very nice. Bike 'lane' on Livermore side is fairly narrow headed toward Isabel but there's the Arroyo Mocho trail on the south side that starts at the bridge; sweet ride. Lots of options now, including a new bike lane over Isabel/580 on the way to Collier Canyon Rd.> Highland > Camino Tassajara > Danville.
