4 Interstate 10 Corridor Study Study Limits: SR-51/SR-202L Mini-Stack to SR-202L Pecos Stack. Began Studied widening the corridor and implementing a localexpress lane system to mitigate weaving issues between SR-143 and US-60. 4

5 Interstate 17 Corridor Study Study Limits: SR-101L North Stack to Interstate 10 Split. Began Studied options for widening the corridor to implement either a local-express lane system or add two general purpose lanes in both directions. Frontage Roads issue. 5

6 Interstates 10 and 17 RTP Funding Interstate 10 widen between 40th St and Pecos Stack... program amount of $648.5 million. Interstate 17 no project specified; awaiting EIS outcome... program amount of $821.6 million. Total RTP Funding of $1.47 billion. 6

7 Managed Lanes are dedicated lanes for one or more user groups. Proactively managed to provide better reliability and/or level-of-service. Primary benefit is travel time savings. Managed Lanes Express Lanes, Orange County, CA. 7

16 Corridor Studies Proposals for I-10 and I-17 SR-143: Flyover ramps for eastboundnorthbound and southboundeastbound. I-10/I-17 Split: Interchange has airspace conflicts. DHOV s: I-10: US-60 and I-10/I-17 Split. I-17: Central Ave, Jefferson/Adams St, between Greenway Rd and Bell Rd, between CAP and Peoria Rd, and Loop 101 North Stack. The Split System Interchange 16

17 Guiding Principals Public Anticipation and Sensitivity Environmental Performance and Economic Opportunity Funding Feasibility Operations and Maintenance Policy The Split System Interchange 17

18 Public Anticipation and Sensitivity Focus on the customer The public deserves improvements for taxes paid. Proposition 400 expiration is NOT in the distant future. Public skepticism may undermine future revenue initiatives. Drive an implementation plan to ensure timely and expedited project delivery. Brand the initiative and promote it. System Interchange, Tempe AZ. 18

19 Environmental Continue to Ensure Environmental Integrity Build upon findings of current environmental analyses: I-10 and I-17 EIS. SR-202L/South Mountain Freeway EIS. Incorporate remediation strategies: Ensure continuity of approach. Speed project delivery. Black Canyon Freeway, Phoenix, AZ. 19

20 Performance and Economic Opportunity Enhance Network Performance Spine represents linkage to support regional vitality. Optimize roadway safety and performance on improved corridors. Identify derived operational and safety performance on the connected corridors. Provide for travel options: Feasible alternative, reliable travel routes on both corridors and arterials. Other improvement techniques, such as express toll lanes. Include availability for HOV, BRT, and other alternate modes where possible. Maricopa Freeway, Phoenix, AZ. 20

21 Funding Feasibility Optimize Solutions Within Budget Provide solutions with cost/budget integrity. Avoid scope creep that produces marginal benefits and added cost. Extend budget constraints to ensure lowest possible operations and maintenance cost. North Stack System Interchange, Phoenix, AZ. 21

22 Operations and Maintenance Provide for Effective Maintenance and Operations Maintenance - Easy, Efficient, Cost Effective: Provide for maximum service life and lowest maintenance costs. Allow for maintenance with the least traffic disruption. Operations - solutions that can readily incorporate: Dynamic traffic management, ITS, fiber optics, etc. Non-traditional: express toll lanes, active traffic management. HOV lanes and direct access. Black Canyon Freeway, Phoenix, AZ. 22

23 Policy Adhere to existing MAG policies across all elements of transportation, including: Safety Environment Arterial Life Cycle Policies ITS Managed Lanes Development Identify policy gaps or those requiring clarification in order to: Facilitate alternatives evaluation in the current initiative. Provide better guidance for future projects/programs. Maricopa Freeway, Phoenix, AZ. 23

24 Example Corridors I-64/US-40, St. Louis, MO The rebuilding and upgrading of ten-miles of pavement, bridges and interchanges in St. Louis. Initial budget $2.5 billion; final cost $550 million. New connection between I-64 and I-170. Additional lane in each direction between Spoede Road and I-170. Increased traffic flow Elimination of short, tight entrance/exit ramps. Addition of dedicated exit lanes. Enhanced safety with wider shoulders. Interchange, Brentwood, MO 24

25 Example Corridors I-495 Capital Beltway Washington, DC Circumferential route in the Washington, D.C. area, connects many radial routes such as I-270, US-29, I-95, I-295, and US- 50. Virginia DOT... Beltway Maintenance... more than 50 deficient structures. Westside and Southside Mobility. Express Lanes to help offset costs for freeway rehabilitation... in exchange for 85-year concession with P3 operator. Capital Beltway, Northern Virginia. 25

26 Example Corridors I-15 Corridor, Salt Lake City I-15 Reconstruction (16.2 miles): Addition of new general purpose and high-occupancyvehicle (HOV) lanes. 130 bridges, seven urban interchanges, and three major junctions with I-80 and I-215. Extensive region-wide advanced traffic management system. Design-build model was motivated by two factors: Strong public support for completing the project quickly to minimize severe traffic congestion. Need to have the project completed before the 2002 Winter Olympics. Reconstruction, Salt Lake City, UT. 26

27 Example Corridors Interstate 5 Columbia River Crossing Three through-lanes in each direction on a segment of Interstate 5. A phased light rail loop in Clark County. Additional span or a replacement bridge with up to two additional lanes for merging and two light rail tracks. Interchange improvements. Capacity improvements for freight rail. Bi-state coordination of land use and system management to reduce demand. New Columbia River Crossing, Portland, OR and Vancouver, WA. 27

28 Funding feasibility. Runway airspace compatibility. Right-of-way availability. Adjacent development. Sensitive environmental receptors. Corridor Constraints Black Canyon Freeway, Phoenix, AZ. 28
