CONSTRUCTION UPDATE
August 2015
After closing for 71 hours on July 9-12, the new Doyle Drive was opened to traffic, eight hours
earlier than expected! Several hundred workers placed over 2,800 tons of concrete, and
removed more than 15,000 tons of materials, during the accident-free weekend.
Although a great new stretch of highway is now open, there’s more to be done to finish the project. Construction
activity will continue into mid-2016 and will include removing the temporary bypass, restoring and reconfiguring
portions of the east end, covering the tunnels, reconstructing Halleck Street and installing landscaping.
Did you know? The name of the roadway is still Doyle Drive, after Frank Doyle, the “father of the Golden Gate Bridge.”
Presidio Parkway is the name of the new roadway design and refers to the construction project.
DOYLE DRIVE BETWEEN THE TUNNELS
TUNNELS
Work will continue into the fall to install barrier rails and
permanent striping and to build a retaining wall between
the northbound and southbound roadways. Temporary
barriers (k-rail) are in place to maintain a safe work zone
adjacent to the highway. Until work is complete, Doyle
Drive is still an active construction zone, and there are
areas without safety shoulders. Please drive carefully
and follow the 35 mph speed limit!
HIGH VIADUCTS

During construction of the northbound High Viaduct,
the southbound High Viaduct was temporarily widened
to accommodate both directions of traffic. Now that
each direction of traffic is moving on its own viaduct,
this widened section of the roadway is being removed,
requiring overnight closures of northbound Highway 1
and Lincoln Boulevard. Later in the year, the girders that
protected the Pet Cemetery during construction of the
High Viaducts will be removed, and access to the Pet
Cemetery will be restored.
Crews will fill in the opening in the roof of the southbound
Battery Tunnel, which was installed during Phase I to
provide necessary ventilation for the tunnel. Now that
each direction of traffic is being carried through its own
set of tunnels and ventilation is provided by jet fans, the
vent is no longer necessary. This work will require lane
closures of Highway 101 and may require closures of
Lincoln Boulevard above the tunnel.
Work will soon occur to prepare to cover the Main Post
and Battery Tunnels with lightweight fill and restore
Halleck Street across the tunnel tops, which is expected
next spring.
REMOVAL OF TEMPORARY DETOUR
The temporary detour that carried traffic during the
three-year major construction in Phase II is being
removed. Crews will crush the asphalt and haul it away
for recycling.

EAST END
Sidewalk restoration work, including installation of barrier rail, will occur along Girard Road to provide bicyclists and pedestrians
with a continuous bicycle lane and sidewalk connection between the Presidio and the Marina.
Gorgas/Richardson Intersection Reconfiguration
Future Crissy Marsh Expansion
Crews are working to reconfigure the Gorgas Avenue/
Richardson Avenue intersection with relocated traffic signals
and a new median island. To reduce potential cut-through
traffic as per the approved environmental document, vehicle
access from Gorgas Avenue to Lyon Street will be eliminated,
and the connection to Lyon Street will become a pedestrian
and bicycle corridor.
In the coming year, crews will begin digging and grading
under the low viaducts to accommodate the future expansion
of Crissy Marsh and the connection to the Quartermaster
Reach wetland restoration project.
