The San Joaquin Valley Air Pollution Control District is urging commuters to get out of their cars and ride bicycles to work on Tuesday.
The district's "Bike to Work Day" was originally scheduled for July but was postponed because of the poor air brought on by summer forest fires that burned over many parts of the state.
The city of Modesto will hold a rideshare information fair at 10th Street Place on Tuesday morning. Also, police officers will escort riders from the Fun Sport Bikes shop in McHenry Village to 10th Street Place.
The air board has other events scheduled in Fresno and Bakersfield next week.
