The Metropolitan Transportation Commission has released its list of the Bay Area’s top 10 most congested freeway commutes, and it should be no surprise to hear that Interstate Highway 80 from Hercules to the Bay Bridge ranked at the very top.
The westbound morning commute toward the Bay Bridge has often assumed the top spot for more than a decade. While it dropped to fourth in 2013, the 17-mile segment of freeway from the state Highway 4 interchange to the bridge has re-emerged as the most daunting traffic hike in the region.
The second most congested commute was southbound Interstate Highway 880 between San Leandro and Milpitas during the morning. Third place was the southbound afternoon commute on U.S. Highway 101 from Fair Oaks Avenue in Sunnyvale to Oakland Road in North San Jose, according to MTC.
The most congested list is put together by factoring in a figure called “congested delay,” which is when traffic moves at 35 mph or slower for a period of 15 minutes or more, MTC officials said. Throughout the Bay Area, congested delay rose by 3-percent last year from the previous year. The congested delay in 2014 was, in fact, a record level, and an increase of nearly 40-percent from 2010. The increase in delays is blamed on an economic boom that is increasing the region’s population and thus inviting more cars onto the roadway.
