>> in this fabulously beautiful persidio national park and near golden gate and running like a scar is this ugly highway. that was built in 1936 at the same time as the bridge and at that time the presidio was an army and they didn't want civilians on their turf. and the road was built high. >> we need access and you have

a 70 year-old facility that's inadequate for today's transportation needs. and in addition to that, you have the problem that it wasn't for site extenders. >> the rating for the high viaduct is a higher rating than that collapsed. and it was sapped quite a while before used and it was rusty before installed. >> a state highway through a federal national park connecting an independently managed bridge to city streets. this is a prescription for complication. >> it became clear unless there was one catalyst organization that took it on as a challenge,

it wouldn't happen and we did that and for people to advocate. and the project has a structural rating of 2 out of 100. >> you can see the rusting reinforcing in the concrete when you look at the edges now. the deck has steel reinforcing that's corroded and lost 2/3's of its strength. >> this was accelerated in 1989 when the earthquake hit and cal came in and strengthened but can't bring to standards. to fix this road will cost more than to replace. and for the last 18 years, we have been working on a design to replace the road way, but to

do in a way that makes it appropriate to be in a national park and not army post. >> i would say it's one of the most ugly structure, and it's a barrier between the mar sh and presidio. and this is a place and i brought my dogs and grandchildren and had a picnic lunch and it was memorable to use them when we come here. what would it look like when the design and development is completed. and we are not sure we want an eight lane highway going through this town. and it's a beautiful area in a national seaport area on the planet. >> the road is going to be so

different. it's really a park way, and it's a parkway through the national park. and they make the road disapeer to the national park. >> and the road is about 20 feet lower, normally midday, you go through it in two minutes. looking back from the golden gate bridge to presidio, you are more aware of the park land and less of the roads. and the viaduct will parallel the existing one and to the south and can be built while the existing one remains in operation. and the two bridges there with open space between them and

your views constantly change and not aware of the traffic in the opposite direction and notice the views more. and the lanes of course are a foot wider than they are today. and they will be shoulders and if your car is disabled, you can pull off to the edge. and the next area, the tunnel portal will have a view centered on the palace of fine arts and as you come out, you can see alkatrez island and bay. and the next area is about 1,000 feet long. and when you come into one, you can see through the other end. it's almost like driving through a building than through a tunnel. and noise from the roadway will be sheltered. and the traffic will be out of view. >> when you come out of the

last sort tunnel and as you look forward, you see the golden dome of the palace of fine arts and what more perfect way to come to san francisco through that gateway. >> it will be an amazing transformation. now you read it as one section, the road is a major barrier and then a wonderful strip along the water. all of those things are going to mesh together. >> right now the road really cuts off this area from public access. and with the new road, we will be able to open up the opportunity in a new way. >> this bunker that we see now is out of access for the general public. we are excited to completely

rework this side and to open up the magnificent views. and what we want to do is add to this wonderful amenity and restore this coastal bluff area and respect its military history and the doyle drive project is allowing us to do that recorrection. and this area is not splintered off. >> and we can see how dramatic a change it will be when doyle drive is suppressd and you have a cover that connects the cemetery to this project. it's historic on the statewide and national basis, but you could rush the project or put thought and time to create

something of lasting public benefit. >> we really want this, for everyone to feel like it's a win situation. whether you are a neighbor that lives nearby or a commuter or user of the park. that everyone will experience a much better situation than they currently have. >> the human interest to me is how people could work out so many challenging differences to come to a design that we believe will give us a jewel. landmark of a place. >> i am sure it will have refining effect like embark did. and there were people about that and no one would think of that today. and when you look at growth and transformation of the embark, the same with doyle. it will be a cherished part of the city and a worthy addition

to what is there. >> it will be a safe and beautiful entrance to a spectacular beautiful city. it will be the entry to golden gate that san francisco deserves.

>> started in 1990. the citizens of the marina district came to the fire department and asked for a program to survive for 3 days. there is a 70 percent chance we will have a 6.5 earthquake. 71 large fires. 40 major rescue operations. [inaudible]. rescue operations there were 34 structure fires we need 275 engines to handle this. we have 41.
