Highway 70 at Highway 100 Intersection and Safety Improvements
Highway 70 at Highway 100 Intersection and Safety Improvements
Highway 70 S (Harding Pike) and Highway 100 currently intersect as a yield-controlled “cross-over” intersection just north of Heady Drive in Nashville, Tennessee. This crossover in conjunction with adjacent signalized intersections, open frontages on both sides of the corridor, and lack of pedestrian infrastructure has resulted in safety concerns along this stretch of roadway. The principal purpose of this project is to analyze the existing and future conditions within the study area in order to provide short-term improvements as well as long-term alternatives for improved safety, new pedestrian connections and increased corridor efficiency. The community plays a key role in identifying traffic and safety concerns based on first-hand experience in the area. Your input will ensure that this project focuses on the issues that matter most to those who use these intersections daily.
This project is part of Vision Zero, a Metro-wide initiative led by the Nashville Department of Transportation and Multimodal Infrastructure (NDOT) aimed at eliminating traffic-related fatalities and serious injuries on Nashville’s roads.

Why we're asking
Highway 70 S (Harding Pike) and Highway 100 currently intersect as a yield-controlled “cross-over” intersection just north of Heady Drive in Nashville, Tennessee. This crossover in conjunction with open frontages on both sides of the intersection and lack of pedestrian infrastructure within the vicinity of the intersection has resulted in safety concerns along this stretch of roadway.

What we want
The principal purpose of this project is to improve the safety and operation of this intersection through community input and analysis of existing and future conditions. We want to ensure that we are appropriately addressing and improving the issues experienced by all road users in this intersection. This project is part of a greater effort and goal of NDOT Vision Zero to reduce and eliminate fatal and serious injury crashes in Davidson County.
What we've learned
Existing conditions have been analyzed in the study area, and data was collected on existing roadway and multimodal infrastructure, turning movement counts during traffic hours, historic TDOT traffic count data, current signal timings, travel time and speed data, and crash data in the study area. Traffic models were developed analyzing vehicle level of service (a measure of traffic operation performance), delay, travel time, and speed.
The existing conditions analysis showed that there has been 85 crashes in the area since 2020, and some crash patterns were revealed, including:
- Northbound left-turning vehicles crashing into southbound through vehicles;
- Running red lights;
- Failing to yield at cross-over;
- Sideswipe crashes;
- Drivers attempting to turn in and out of driveways.
The image below shows a diagram of recent crashes in the area.

How you can help
The purpose of this engagement is to gather community input and local insight on traffic flow and safety issues. Input from daily commuters and residents in the area is essential to bring forward issues and ideas that may not be captured through data alone.
