IMPROVEMENT PLAN: IMPLEMENTATION (Phasing Plan)

Since the improvement concept is so large, the study team divided the project into smaller construction projects. Each of these projects still provided a significant benefit to the traveling public and can be built within a four year time frame. The projects were prioritized and coordinated with the proposed improvements associated with the adjacent I-435 and US 69 interchange. From this effort the following Phasing Plan was developed:

Phasing plan projects

• Project 1 - Yellow Project
  The Yellow Project will address the back-up of traffic on the existing WB I-435 to SB I-35 flyover ramp. It will also address the heavy SB and NB I-35 traffic between 119th Street and I-435.Estimated construction cost is $16 million in 2016 dollars.
• Project 2 - Orange Project
  The Orange Project will address the EB traffic congestion between K-10 and I-35. It will also address the heavy traffic on NB I-35 just north of I-435. The Orange Project, in conjunction with the Yellow and I-435 & US-69 Red Project, addresses nearly 80 percent of today's problems within the interchange area. Estimated construction cost is $244 million in 2016 dollars.
• Project 3 - Green Project
  The Green Project will improve through traffic capacity on I-435 and K-10. In combination with the Orange and Yellow Projects, the Green Project addresses nearly 70 percent of the future anticipated problems within the interchange area. Estimated construction cost is $191 million in 2016 dollars.
• Project 4 - Red Project
  The Red Project completes the improvements addressing all the remaining traffic issues identified within the interchange area. Estimated construction cost is $132 million in 2016 dollars.
