The Presidio Parkway road construction project is scheduled to close sections of Doyle Drive on the south side of it’s connection to Hwy 101 on one or both of the June 12 & 13 and June 19 & 20 weekends. I can’t imagine that the alternate routes will be traffic free.
Information and updates on the closures can be found at http://www.presidioparkway.org/construction_info/
You can also sign up for email updates on upcoming closures if you are a frequent Golden Gate Bridge traveler.
Happy (and patient) driving!
