I-680 Sunol Northbound Express Lane Project
The construction contract was awarded in late November 2017. Construction begins spring 2018. The I-680 Sunol Northbound Express Lane project will add a new 9-mile HOV/express lane and associated improvements between Auto Mall Parkway and SR-84.

I-680 Southbound Express Lane project
Plan to widen the freeway and structures to meet current standards, construct auxiliary lanes, rehabilitate the roadway, and implement the first High Occupancy Toll (HOT) lane facility in northern California which will allow single occupant vehicles to use the HOV lane for a toll.

State Route 237 Express Lanes Project
Phase 2 will extend the 237 express lanes from N. 1st Street to Mathilda Avenue in Sunnyvale, in both directions. In other words, those driving from Milpitas to Mountain View will NOT be able to get into the carpool lanes until the 101 South exit. We need to protest this!

Scenic Drives

Bay Area Backroads
Go “day tripping” to places near and far. KRON TV offers hundreds of ideas in the South Bay Area and further away.

Calaveras Road to Sunol
Calaveras Road varies from 2 lanes in Milpitas and the 84/680 end in Fremont down to 1 lane in the middle. The south half was recently repaved from Milpitas to the Alameda County line, about 2/3 of the entire ride.

Calaveras – Sierra Rd Loop
Scenic drive in the snowy mountains east of Milpitas and San Jose, California.

California Roadside Rest Areas
Plan your rest stops in rural areas.

Mt. Hamilton Road
Take this mountain road between Alum Rock and Patterson. Do fill up your thirsty steed because if you decide to continue east down the other side of the mountain, it will be another 70 miles to the next gas station. Very windy and steep. Not for the faint-hearted.

Santa Cruz Mountains Roads
A lovely drive is the one through the redwoods from Woodside, over to the coast, down to Santa Cruz, and back over Rt. 9 through Boulder Creek and Big Basin State Park to Saratoga.
