PHASE I: December 2009 - Spring 2012
Phase I was completed
on April 30, 2012 when Doyle Drive traffic was transferred onto a temporary bypass
and the completed southbound structures.
PHASE II: 2012 - 2015
Transferred onto a Temporary Bypass
In April 2012, traffic was shifted onto
a bypass next to Doyle Drive with five lanes - wider than those on the existing
Doyle Drive - and with opposing traffic separated by a median barrier.
Highway 1 ramps are closed: NB Doyle Drive to SB Park Presidio/Hwy 1 and NB Park
Presidio/Hwy 1 to SB Doyle Drive. See
details about the ramp closures.
Weekend Closure of Doyle Drive
In 2015 there will be a weekend closure of Doyle Drive to transfer traffic from
the temporary bypass onto the final Presidio Parkway.
Traffic on the Final Presidio Parkway
major construction will be complete and traffic will be on the final Presidio Parkway.
Final project activities after this will include removal of the temporary detour
