Drivers slogging through Bay Area freeways during the rush-hour commute are spending more time crawling along at speeds of less than 35 miles an hour, with traffic congestion up 80 percent since 2010, a new report released Monday by the Metropolitan Transportation Commission (MTC) found.

The average driver in 2016 spent roughly 3.5 minutes per commute traveling less than 35 mph, a new record and a 9 percent increase over the previous year. It also marked the fourth consecutive year that weekday traffic congestion around the region reached a new high. Or new low, depending on how you view it.

Ask MTC spokesman John Goodwin, and it’s a good problem to have.

“As I look at the map and as I look at the data, so much of it is tied to the strength of the regional economy,” he said. “If you want meaningful congestion relief, a recession is a great way to do that.”

But the reality is a harsh one for those who suffer through it, and one that Netflix employee Andreas Schafhauser knows all too well. He makes the roughly three-hour roundtrip commute from Walnut Creek to Los Gatos and back each day.

“That’s on a good day,” he said, referring to the time-sucking traffic trudge. “It’s definitely gotten worse.”

Schafhauser has tried every combination of public transit possible, typically opting to take his employer-provided shuttle when its schedule aligns with his.

Evidence of booming growth — where people are finding new jobs and new homes — is written into the commute patterns, Goodwin said, pointing to new additions to the top 10 list. The evening commute on State Route 4 through Concord in Contra Costa County rose from 16th to 10th place, usurping the p.m. Highway 101 slog through San Mateo.

The report also showed increasing congestion along other Contra Costa County thoroughfares, with the State Route 24 evening commute toward Walnut Creek moving from 10th to ninth place and the northbound evening commute on Interstate 680 from Crow Canyon Road to Contra Costa Boulevard coming in at No. 8, up from No. 11 one year ago.

“There is comparatively less expensive housing to the east of (those locations),” Goodwin said, “which is an important factor.”

But the top three congested arteries remained the same: that’s the northbound evening commute over the Bay Bridge from San Francisco to the East Bay, when more than 14,000 drivers vie for space in line to cross the bridge. Trailing the evening Bay Bridge rush is the westbound Interstate 80 corridor, extending from the SR 4 interchange near Hercules to Fremont Street in San Francisco.

This year, however, the westbound I-80 squeeze earned the dubious distinction of becoming an unrelenting grind; it’s the only segment among the region’s top 10 congested corridors to involve a morning commute, and the only one to remain clogged for one stretch or another throughout the day — with no mid-day respite.

But the traffic isn’t only in the East Bay and San Francisco. Coming in at third place was the southbound Highway 101 commute from Mountain View to San Jose and, in sixth place, the southbound evening commute along Interstate 280 from the Foothill Expressway to Virginia Street in Santa Clara County.
