SUNOL (KPIX 5) – A small grass fire along southbound Interstate 680 near Sunol has led to a massive backup on the major East Bay highway early Monday morning.
According to officials, the fire broke out near Andrade Road, just past the I-680 / Highway 84 interchange around 5:30 a.m.
The fire appeared to be out as of 6:50 a.m., but the right lane and shoulder remain blocked. Southbound I-680 is backed up through Pleasanton and to the Dublin interchange, while westbound Highway 84 is backed up to Vallecitos Road.
