2 Meeting Agenda 2

3 History & Overview Circle Interchange was built in the late 1950 s and early 1960 s, and the facility is in need of major repair or reconstruction. 3

4 History & Overview American Transportation Research Institute (ATRI) + Federal Highway Administration Slowest, most congested highway freight bottleneck in the nation More than 400,000 vehicles a day travel through the interchange On average, 940 crashes per year 4

5 Purpose & Need Address the existing & 2040 transportation needs Improving safety Improving mobility Improving facility deficiencies 5

6 UNIVERSITY VILLAGE Surrounding Neighborhoods 6

7 Phase I Study Process We Are Here 7

8 Alternatives Development Widening Flyover (3 rd level) Second level flyover (4 th level) Underneath I-90/94 Consolidation of ramps Removal of Ramps 8

9 Preferred Alternative: A-7.1C 9

10 Key Features of the Preferred Alternative 4 Lanes I-90/94 Reduced Delay 2 Lane ramps 10

11 Northbound by-pass Improving weaves & short merges Improving traffic weave at Taylor St. exit Key Features of the Preferred Alternative 11

12 Kennedy Expressway S. Halsted St. W. Harrison St. W. Van Buren St. W. Jackson Blvd. W. Adams St. W. Monroe St. W. Madison St. W. Washington Blvd. W. Randolph St. W. Lake St. Provides a slip ramp from EB to NB to allow all traffic to exit downtown Moves the center lefthanded on-ramps for Adams and Jackson to the C-D Road All existing NB exits will remain Monroe Street bridge reconstructed 12

13 Kennedy Expressway S. Halsted St. W. Harrison St. W. Van Buren St. W. Jackson Blvd. W. Adams St. W. Monroe St. W. Madison St. W. Washington Blvd. W. Randolph St. W. Lake St. Longer Madison on ramp Right-of-way needed between Quincy and Jackson Separate exit ramps for Adams and Jackson 13

26 Noise Study 26

27 Traffic Noise Analysis Existing conditions provides the basis for evaluation IDOT Policy follows FHWA Noise Abatement Criteria (NAC) Traffic noise impact when predicted noise level approach, meet or exceed the NAC Residential, Parks, Schools, Playgrounds, Hospitals (67 dba) Offices, Hotel, Restaurants (72 dba) 27

28 Traffic Noise Analysis Evaluation Process Noise Monitoring Traffic Noise Model (TNM) for 2040 conditions Determine impacts and assess potential mitigation 28

29 Traffic Noise Analysis Traffic noise based on these factors Speed Distance Percentage of trucks Topography / Elevations 29

30 NOISE RECEPTION SELECTION Common Noise Environment (CNEs) 52 CNEs for project 30

31 Traffic Noise Evaluation GOALS: Must be both feasible and reasonable Constructible Achieves at least an 8 dba reduction for at least one benefited receptor Economically reasonable $24,000 + adjustment factors per benefited receptor 31

32 Likely Traffic Noise Abatement Measures OUTDOOR COURTYARD (SANGAMON STREET) CNE LOFTS CNE 7 ST. PATRICK S CHURCH CNE 47 & 48 UIC TENNIS COURTS CNE 33 MULTI-UNIT RESIDENCES CNE 22 LIKELY NOISE ABATEMENT MEASURES LIKELY NOISE ABATEMENT MEASURES 32

33 Likely Traffic Noise Abatement Measures Next steps. Viewpoint solicited from benefited receptors (property owners and tenants) 33% response rate goal Viewpoints tallied Need greater than 50% of responses received in favor of likely abatement measures 33

34 Construction Sequencing 34

35 Construction Sequencing Stage Elements Year Stage 1 Harrison Street Morgan Street I-90/94 (NB Roosevelt to Harrison ) Halsted Street Peoria Street NW Flyover 1 Stage 2 I-290/Congress Parkway 2 Stage 3 I-90/94 Van Buren Street Monroe Street Jackson Boulevard Adams Street Remaining Ramps 3 & 4 35
