Franklin's East Main Street bridge over the Harpeth River is finally getting its long-anticipated overhaul, with a full replacement set to kick off later this summer. The nearly 100-year-old span that carries a busy stream of traffic into downtown will be rebuilt with modern hydraulic and safety upgrades that officials say will also reshape how the riverfront handles floodwater.
The Tennessee Department of Transportation is steering the project as part of a broader State Route 6 package that covers lane and bridge improvements across Maury and Williamson counties. The SR-6 corridor work includes replacement of bridges over the Harpeth River and treats the larger SR-6 widening as a long-range effort in the state's 10-year plan, which the agency currently lists as under development, according to the Tennessee Department of Transportation.
Local reporting says crews are expected to break ground later this summer, with TDOT aiming to wrap up the replacement by December 2028. During construction, at least one lane in each direction is expected to remain open so downtown access is not completely choked off. The current bridge, built in the late 1920s and carrying traffic for roughly a century, is due for a full replacement due to age and condition reasons, as reported by WKRN.
Floodplain Work And Downtown Context
City planning documents show the East Main corridor includes a large swath of the Harpeth River's 100-year floodplain, which restricts how nearby properties can be developed and where new buildings can go. Hydraulic improvements tied to the bridge replacement could lower flood risk and free up land that has been constrained by floodplain rules, potentially shifting redevelopment options along the riverfront, according to Envision Franklin.
Traffic, Access And What To Expect
TDOT plans to stage the project so traffic can continue to move through downtown, a playbook the agency has used on other Harpeth-area bridge jobs to avoid extended full closures. Drivers should brace for flagging operations, intermittent lane shifts, and overnight work windows throughout the multi-year construction period, according to TDOT.
In a statement to WKRN, TDOT Region 3 communications officer Erin Zeigler said, "Hydraulic and safety improvements will occur as part of the bridge replacement project." Local reporting also noted that the work could remove several properties from the floodplain upstream of the bridge, which officials say will benefit nearby homes along the river.
The bridge replacement is set to be a daily backdrop in Franklin through 2028, with staggered construction, shifting traffic patterns, and periodic impacts to riverfront access. City and TDOT officials expect to schedule public meetings as design details are finalized, and this story will be updated when meeting dates and detour plans are announced.
