Don't fill in your calendars or make travel plans until you've read the weekend preview from KCBS Radio's traffic reporter Bob Pryor. His traffic tips and event suggestions cover the entire Bay Area and are available every Friday. If you're looking for up-to-the-minute information, follow our Twitter account. If you've got a question or a traffic tip of your own, you can call our Phone Force anytime at (415) 391-KCBS.

Street closures will abound in Oakland this Sunday as the Oakland Marathon and Running Festival celebrates its 10th anniversary. If that’s not enough running for you, set aside Saturday morning as well. That's when the Heart and Soles Run will take place in Santa Clara and San Jose.

Alternatively, you could strap on your dancing shoes for Saturday’s extremely colorful Holi Festival in Foster City. 

San Francisco will host the Bay Area Brewfest on Saturday, complete with Food Truck Alley, so you’ll have ample calories to justify the running you just did or the running you’re about to do. Oh, and on Saturday night, Caltrans serves up some road work near Sears Point in Sonoma that might have you recalculating your travel plans before GPS does it for you. 

If you're willing to make a longer trip, you could also head to Salinas for the California International Air Show on Saturday and Sunday. The US Navy’s Blue Angels and KCBS Radio personalities George Rask and Peter Scofield will be there. Be sure to say hello. 


Sat, Mar 23 at 8am: Santa Clara and San Jose: Heart and Soles Runs of varying length, including one for kids. The race starts on Franklin STreet alongside Santa Clara University's campus and makes it way through Avaya Stadium before returns to the campus for a festival on the Franklin Street pedestrian mall. There will be street closures from 7am to 10am.

There will be many street closures in downtown Oakland, Jack London Square, West Oakland, Grand Lake, into Emergyville and onto the Bay Bridge. 

  • Pro tip: AC Transit bus service will be severely disrupted between 6am and 3pm. See details here. For more detailed information, about traffic disruptions, you’ll want to at least skim this list of street closures and this list of detours. Most street closures will be gone by 1:30pm.
  • Pro-tip #2 No bikes will be allowed on the Bay Bridge pedestrian bike path from 8am to noon. 


Sat, Mar 23 from 11am-3:30pm: The 8th annual Foster City Holi Festival takes place at the Recreation Center at Leo J. Ryan Park on Shell Blvd. People throw colored powder, enjoy Indian song and dance and food, celebrate the return of spring. 

  • Pro tip: SamTrans Route 256 goes to Hillsdale Blvd at Shell Blvd, which is a 6-minute walk from the Rec Center. Parking is available in the South Recreation Center lot, at the Community Center/Library, and at nearby City Hall.
  • Areas and roadways affected: In Foster City, possible extra traffic on Shell Blvd, E Hillsdale Blvd.


Sat, Mar 23 from noon-4pm or from 5:30pm-8:30pm (pick your session): San Francisco: 8th annual Bay Area Brewfest takes place at Pier 35 on the Embarcadero near Bay Street. Unlimited samplings of 200 beers from 70 breweries, along with a deejay, photo booth, and food for sale from ‘Food Truck Alley’. Event is rain or shine.

  • Pro tip: Discounted Designated Driver (non-drinking) tickets are available. For people taking mass transit, MUNI’s F-line streetcar , it’ll take you right to The Embarcadero and Bay Street, location of Pier 35 and the Brewfest.


Sat, Mar 23 from 7pm-10am Sunday morning: Sonoma County: Highwayy-37, east of Highway-121/Sears Point will be closed overnight in both directions to allow for emergency repairs to a railroad crossing. Local access will be available for residents and emergency vehicles only.

Westbound SR-37-Detour: During the closure, motorists coming from Vallejo should take NB-29 to Napa, then WB-12 out to Schellville/Big Bend, then SB-121, and re-enter WB-37 at the Hwy-121/Hwy-37 interchange.

Eastbound SR-37-Detour: Motorists traveling eastbound from Novato should take NB-121 to Big Bend/Schellville, then EB-12 to Napa, then SB-29 to Vallejo, then re-enter eastbound Hwy-37 at the Hwy-29/Hwy-37 interchange.

  • Pro tip: Caltrans has information about detours that drivers could use to avoid the shutdown. Because there are no good alternate routes, the detour is a long one that takes you miles out of your way, at night. If you can reschedule your travel outside this Saturday-night-into-Sunday-morning timeframe, that would be the best solution.
  • Areas and roadways affected: Extra overnight traffic on Highways 12, 121, 29.
