Preliminary Noise Recommendations
The North Split project team recently completed the Traffic Noise Technical Report, which evaluates the potential noise impacts of the proposed improvements within the project area. INDOT is seeking input from residents and property owners who would benefit from the construction of noise barriers for the I-65/I-70 North Split Project. This project includes replacing and repairing deteriorating bridges, upgrading pavement conditions, reducing congestion, and improving safety at the I-65 and I-70 interchange on the northeast side of downtown Indianapolis.
Noise Barriers
Based on the guidelines outlined in INDOT’s Traffic Noise Policy, recent analyses determined that noise barriers were determined to be feasible and cost-effective at five locations:
- Noise Barrier NB3E – Westbound I-70, along the edge of the north shoulder from Commerce Avenue to Valley Avenue, near the Martindale-Brightwood neighborhood (See the elevation and section views)
- Noise Barrier NB3W – Westbound I-70, along the edge of the north shoulder from approximately 240 feet west of Lewis Street and Commerce Avenue, near the Martindale-Brightwood neighborhood
- Noise Barrier NB4 – Northbound I-65, along the edge of the north shoulder between College Avenue and Alabama Street, near the Old Northside neighborhood (See the elevation and section views)
- Noise Barrier NB5 – Southbound I-65, along the edge of the south shoulder between College Avenue and Alabama Street, near the Chatham Arch and Saint Joseph neighborhoods (See the elevation and section views)
- Noise Barrier NB7 – Southbound I-65/Westbound I-70, along the edge of the west shoulder between 10th Street and Ohio Street near Massachusetts Avenue and the Lockerbie Square neighborhood
(See the elevation and section views)
As part of the project development process, INDOT is asking residents and property owners who would benefit from the construction of a noise barrier whether they want the barrier to be constructed. FHWA and INDOT will consider the feedback received before making a decision whether or not to construct each noise barrier.
