Overview • Top MoDOT Priority • A Funding challenge • Desperately needed • EIS is Critical Milestone
What’s the Problem? • Aging, crumbling infrastructure • Overpasses not tall enough • Interchanges too close • On/Off ramps too short
Goals for Reconstruction • Better traffic flow • Enhance surrounding communities • Last another 40 years
Purpose for The New I-64 • Freeway Condition & Interchange Features • Capacity • Traffic Safety • Operation and Congestion • Community Redevelopment
Starting The Process • Started with Single-Points at every interchange • Driver familiarity • Dense urban area • High volume of traffic
Single Point Urban Interchange cloverleaf single point

Comparison of Interchanges diamond single point
Traffic Analysis • Traffic Counts on Existing • Project Future Traffic
Regional Traffic Model • Spans from I-70 to I-44 and I-270 to downtown • Includes non-state roadways
Construction Staging • Depends on Funding • Best Case = 6 years • Worst Case = 16 years
Construction Traffic Diversion • I-70 and I-44 • MetroLink Cross-County line open • Signal timing on parallel roads • Encourage flex time, telecommuting and carpooling to reduce rushes
Screening Options • No Build and Build Options • Two levels of screening – initial & refined EIS alternatives. • Most of the options subcommittees discussed were evaluated early • Those decisions are documented in the EIS in Chapter 2: Alternatives
Selecting the Preferred Alternative Interchange at I-170 • Stacked or flat from Brentwood to Hanley? • Shifted north or south from McCutcheon to Brentwood? • Oakland Avenue • Eastbound Off Ramp or Not?
