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

Preliminary Planning NEPA Partial Design Procurement Final Design and Construction

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
• r 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 Alternatives

Transportation 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 Questions

Can 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 Questions

How 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 Questions

What 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

Public Involvement
