  • CTC Presentation
  • April 15-16, 2009

2
Project Purpose
  • Improve the seismic, structural, and traffic
    safety of the roadway within the setting and
    context of the Presidio of San Francisco and its
    purpose as a National Park

3
Doyle Drive History
  • Built 1933-36 to bypass Army Base
  • (Under Golden Gate Bridge Highway District)
  • 1945 Became a State Route
  • 2000 Began new EIS/EIR for replacement
  • 2005 Completed Draft EIS/EIR
  • 2005 Introduced Parkway Alternative
  • 2007 Preferred Alternative selected
  • Dec. 18, 08 Record of Decision (ROD) signed

4
Doyle Drive Existing Condition
  • Structural deterioration
  • No median
  • No shoulders
  • Narrow lane widths
  • No direct Presidio access

5
Significance of Doyle Drive
  • Interregional Route
  • Over 100,000 vehicles per day
  • Vital to the economic and social well being of
    region.
  • Designated as a Post Disaster Recovery Route
  • Located in the Presidio, a National Historic
    Landmark District

  • Project Acceleration

11
Why Accelerate ?
  • To achieve seismic safety earlier
  • To reduce risk of cost growth
  • To meet Economic Stimulus timetable
  • To take advantage of the favorable market
    conditions
  • Help create jobs and support the local and
    regional economy

12
Split Contracts
  • Pre-Construction Contracts
  • Contract 1 Environmental mitigation
    (Built-Environmental Treatment Plan) Active
    through roadway contracts
  • Contract 2 Utility Plan and Relocation
  • Roadway Construction Contracts
  • Contract 3 Southbound Presidio Interchange/High
    Viaduct
  • Contract 4 Southbound Battery Tunnel and
    At-Grade Detour
  • Contract 5 Girard Interchange, Low Viaduct and
    Main Post Tunnels
  • Contract 6 Northbound Battery Tunnel
  • Contract 7 Northbound Presidio Interchange/High
    Viaduct
  • Contract 8 Landscaping

Presidio Parkway Simulation
21
  • Presidio Parkway
  • Multi-modal Enhancements

22
Presidio Parkway
  • Setting and Context
  • Guide Design
  • Provide opportunity to support transformation of
    the Presidio from a military base to a National
    Park
  • Offer opportunity for integrated, intelligent
    design appropriate to the surroundings

23
Presidio Parkway
  • Setting and Context
  • More than a roadway
  • A network of areas and connections within the
    Presidio

24
Existing Doyle Drive Connections
  • Facility built to restrict access to military
    base
  • 2 connections across Doyle Drive

25
Presidio Parkway Future Connections
  • Enhanced access to/from/within the Presidio
  • 9 connections across Doyle Drive
  • Increase multi-use trails and pathways within the
    Presidio

  • Questions?

36
The Presidio
37
Presidio ParkwayKey Design Goals
  • Reduce mass and scale of the facility
  • Reduce speeds entering city streets
  • Parkway and not freeway standards
  • Over 100 design exceptions
  • Minimize conversion of park land to highway
  • Enhance the multi-modal network within the
    Presidio
  • Consistent with land use plans
  • Presidio Trust Management Plan
  • Presidio Trails and Bikeways Master Plan
  • Presidio Vegetation Management Plan

38
Existing Battery Bluff
  • Current roadway severs connection

39
Existing Main Post /Crissy Field Area
  • Current roadway reduces connections and is a
    visual barrier
