Tennessee, like all states, is facing increased demand on its transportation infrastructure. The Interstate 24 corridor, a 185-mile stretch from Kentucky to Georgia has been identified in the Tennessee Department of Transportation (TDOT) Long Range Transportation Plan (Plan GO) as critical to statewide mobility and regional connectivity. One critical segment of this corridor deemed high priority is the “Moccasin Bend” segment tucked in between the Tennessee River and a steep bluff in downtown Chattanooga.


TDOT needed a high accuracy 3D model of this complex area in order to evaluate many different multi-modal design alternatives. Continental Mapping brought a mobile lidar solution to the problem. Mobile lidar, when fused with aerial lidar and aerial imagery, creates a dataset that allows for complex, high accuracy design alternative development, and provides a cost-effective reusable 3D mapping dataset that can be used for years to come.

The demand on transportation infrastructure is up, along with fuel efficiencies, causing less taxable fuel to be consumed. The resulting revenue shortfalls make asset management programs essential to take care of assets that are already in place and manage the long term life of overall asset inventories. Asset Management, a systematic approach leveraging complete data sets, allows for accurate assessment of risk and investment. Asset management helps make sure funding is available for the highest priorities.
