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)
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
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 Visit Major Moves 2020 web page

Noise Basics
Federal Highway Act of 1970 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.
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
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
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
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
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
Noise Walls
Wall 1 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
