Driving in Byron: What to Know
Byron's average commute is about 41 minutes, well above the state average of 29, and that ranks 9th of 52 places in the county. About 72% of workers drive alone, and no one in the data rides public transit. Some 86% of households have two or more vehicles, so many families insure more than one car. SR-4 runs through or near town, and the CHP patrols it, so a multi-car policy and solid liability limits make sense.

More About Byron
Byron is a small unincorporated community in the eastern Contra Costa County countryside, where the Delta meets open farmland and wide skies. Some highlights:
- Byron Hot Springs history. In the late 1800s and early 1900s, the area was home to a famous resort hotel built around its mineral springs, and that story is still part of local lore.
- Byron Airport and the skies. The small county airport hosts a lively scene of private pilots, and the open fields around it make for big-sky views and great sunsets.
- Delta waterways. The California Delta's sloughs and channels are close by, with boating, fishing and quiet waterside scenery just a short drive away.
- Rolling East County hills. Grassy hills dotted with wind turbines frame the town, and Los Vaqueros Reservoir, about 15 minutes away, offers trails, fishing and wildlife watching.
