I-65/I-70 North Split Project
Presentation updated February 2018
• Planning documents do not identify a preferred alternative
• Early in NEPA process• Not doing final design
Project Status

We are here
North Split Interchange:
• Second-most heavily-traveled interchange in the state
• Accommodates over 214,000 vehicles per day
• Is operating beyond capacity
• Constructed between 40 and 50 years ago
• Does not meet current design standards
Need for Project
Need for Project• Existing 32 bridges need rehabilitation
or replacement due to structural conditions
• Deteriorating pavement conditions require constant repair and patching for roadway and shoulders
• Current interchange has complex lane change configurations
The EA studies impacts on homes, businesses and the natural environment
• Cultural Resources – Historic sites and districts (Section 106)
• Environmental Justice – Minority and low-income populations
• Additional public outreach in low-income and minority communities
Environmental Assessment (EA)
Environmental Assessment (EA)• Noise – Projected changes of noise
levels and their effects on local neighborhoods
• Connectivity – How to maintain connections to local roads, trails, and pedestrian and bicycle facilities
• Coordination – Input from state, local and federal resource agencies and permitting agencies, e.g. IDNR, IDEM
Alternatives• As part of NEPA, investigating a wide
range of alternatives
• Two-stage screening study• System Level• Project Level
• System Level report will be available this spring for public review & comment
• Public information meeting
REMINDER: No preferred alternative yet
System Level Screening Study• Large scale review of alternatives for
interstates downtown
• Evaluate function, impacts and costs
• Considering full downtown interstate system
• Results will guide Project Level Screening of North Split interchange alternatives
• Project Level Screening then defines alternatives for the environmental study
Travel Demand Management
• Interstate Diversion• Increase I-465 capacity and implement
actions to divert traffic away from downtown interstates
• Transit• Make major regional transit investments
to reduce travel demand on downtown interstates
System Level Screening AlternativesTransportation System Alternatives
• No-Build
• Upgrade existing interstates • Including North Split
• Replace existing system
• Depress downtown interstates
• Replace interstate sections with boulevards
• Surface boulevards + interstates in tunnels
• New interstate links
• Past studies show most traffic on downtown interstates is local
• One indicator is peak period traffic, which is primarily home-to-work travel
• I-70 east has the highest peak hour volumes in the state, with 65% inbound in the morning
• I-65 from the south is 70% inbound in the morning
System Level Screening – Key QuestionsCan we divert high volumes of downtown traffic to I-465?
AM Peak Hour inbound Trip Pattern –Indianapolis Travel Demand Model
A 2003 Purdue study showed the following impacts when I-65 /I-70 was closed during Hyperfix:
• Pennsylvania St (south of Fall Creek) 46% more traffic
• Delaware St (south of Fall Creek) 112% more traffic
• Fall Creek/Binford (Illinois to 56th) 35% more traffic
• College Ave (Washington to 10th) 195% more traffic
• East St (10th to Washington) 75% more traffic
• West Street (I-65 to I-70) 78% more traffic
System Level Screening – Key QuestionsHow will local and neighborhood streets be impacted?
• Preliminary cost estimate for the North Split interchange: $250 to $300 million
• Estimated cost for peer city tunnel/ boulevard: $3.5 billion
• Plus $10 million/year for maintenance• I-81 in Syracuse, New York (1.6 miles)
• System Level Screening Study will provide preliminary cost estimates for alternatives
System Level Screening – Key QuestionsWhat would it cost to replace the existing system?
Robust public involvement plan with numerous stakeholders – neighborhoods, employers, local and state officials.
• Project website, social media, text alerts and e-newsletters
• Media relations
• Public meetings
• Community Advisory Committee (CAC)
• Presentations to local groups and key stakeholders
