SR 48 Trenton Road

The expansion of a 4.19-mile segment of a rural two-lane road to an urban four-lane corridor included 12-foot-wide lanes, a dedicated center turn lane, designated bike lanes, and sidewalks. Additionally, the project incorporated new roadway alignments, the construction of retaining walls, updated signalization, and the replacement and widening of an existing bridge


Tasked with a complex expansion, the team faced the challenge of coordinating more than 320 right-of-way tracts while minimizing land acquisition to meet the TDOT's requirements. A key aspect of the project was the integration of the state’s first continuous flow intersection, which required educating motorists on safely navigating the new road design.


Leveraging their expertise, the team effectively managed the extensive coordination of land tracts and adhered to TDOT's directive to limit land usage. The introduction of Tennessee's first continuous flow intersection by the team was meant to reduce vehicular conflict points, particularly for left-turning traffic, while enhancing overall traffic safety. To address potential driver uncertainty, the team developed an animated instructional presentation – showcased at a public meeting and made accessible on the TDOT website – that illustrated how to confidently and safely traverse the new intersection configuration.
