6. Project Overview I-65 Added Travel Lanes Project
Added lanes project from S.R. 38 (Exit 168) to S.R. 25 (Exit 185)
Third lane in each direction (NB and SB)
Additional lanes will be constructed from median
Noise walls to be constructed
Wall 1 – East side of I-65 just north of S.R. 26 and Lafayette Visitors Center
Wall 2 – West side of I-65 just north of S.R. 26 (opposite side of interstate across from Wall 1)
Wall 3 – West side of I-65 north of S.R. 26 (north of Wall 2)
Wall 4 – West side of I-65 north of S.R. 26 extending to Eisenhower Road (north of Wall 3)

7. I-65 Added Travel Lanes Purpose and Need Enhance safety Improve travel
Add capacity
Extend life of the interstate
The purpose of this project is to improve overall traffic operation by reducing congestion

8. I-65 Added Travel Lanes Major Moves 2020 Project
Legislative action to authorize $400 million in state funds
Expand heavily-traveled interstate corridors to 3 lanes in each direction
Projects constructed within existing right-of-way
Design-build projects to expedite timeline for completion

Typical section

10. Noise Basics Federal Highway Act of 1970 INDOT Traffic Noise Policy
Mandated Federal Highway Administration (FHWA) to develop standards for traffic noise.
Regulations are found in 23 CFR 772.
INDOT Traffic Noise Policy
States are required to develop & implement noise policy based on 23 CFR 772 standards. FHWA must review and approve state policies.
The most current update of INDOT’s Traffic Noise Policy was July 2011.

11. Noise Analysis Process
Identify areas of frequent outdoor human use
Front or backyards of residences, balconies or patios of apartments, outdoor seating at commercial properties, recreational areas
Field measurement of existing noise levels
Future noise level prediction based on year 2035 traffic forecasts
Determine impacts
Evaluate abatement measures for impacts

12. Noise Analysis Process
FHWA Traffic Noise Model (TNM) 2.5
3D modeling software used to analyze existing and projected traffic volumes & speeds
Roadways, pavement, terrain, grass, and receiver locations are also added to the model
Generates existing and predicted future noise levels
Identifies noise impacts
Evaluates noise barrier effectiveness

13. Noise Analysis Process
Noise impact occurs when either:
Predicted sound level approaches or exceeds Noise Abatement Criteria (NAC)
67 dBA for residences
Approach NAC = 66 dBA
Predicted sound level substantially exceeds existing sound level
15+ dBA increase

14. Noise Barrier Evaluation
Feasible
Engineering & environmental considerations
5 dBA for a majority of impacted receptors
Reasonable
Cost effective
INDOT uses $30/square foot to estimate barrier cost
Cost per benefitted receptor of $25,000 or less is considered cost-effective Cost per benefitted receptor goes up to $30,000 if the majority of the homes were built prior to initial construction of the roadway
7 dBA reduction for first row receptors
Benefitted receptors support
Support for noise abatement by majority of benefitted receptors

15. Noise Survey
Noise analysis study recommends areas where noise wall is reasonable and feasible to build
Property owners and tenants benefitting from noise reduction are surveyed to determine their preferences regarding proposed wall(s)
A positive response rate over 50% must be received from benefitted receptors
A noise survey package is sent to benefitted receptors

16. Noise Walls Wall 1 Wall 2 Wall 3 Wall 4
East side of I-65 just north of S.R. 26 & Lafayette Visitors Center
Height ranges from 15ft to 19ft with estimated length of 2500ft
Wall 2
West side of I-65 just north of S.R. 26 (opposite side of interstate across from Wall 1)
Height ranges from 9ft to 17ft with estimated length of 3000ft
Wall 3
West side of I-65 north of S.R. 26 (north of Wall 2)
Height ranges from 12ft to 20ft with estimated length of 2600ft
Wall 4
West side of I-65 north of S.R. 26 extending to Eisenhower Rd (north of wall 3)
Height ranges from 10ft to 20ft with estimated length of 1600ft

17. Noise Barrier Types
Typical noise barrier has a panel design

18. Noise Barrier Types
Noise wall texture is usually either block wall design or panel design
