A New Door onto I-840: Murfreesboro Signs a $54.7 Million Deal for the Cherry Lane Extension
Interstate 840 has run along the top edge of Rutherford County for well over a decade now — the southern half of Nashville's outer loop, finished in 2012, built to move freight and commuters around the metro rather than through it. For Murfreesboro, it has always been slightly out of reach. There are only so many places you can get on it, and the roads that feed those places were laid out for a much smaller city.
On Thursday, July 23, City Council moved to change that. Members approved a $54.7 million agreement with the Tennessee Department of Transportation for Phase 3 of the Cherry Lane Extension — a project that will build a brand-new interchange at I-840 and 2.4 miles of five-lane roadway across northwest Murfreesboro.
What the money buys
The estimated total comes to roughly $54.72 million, and the funding split is the part worth reading twice. Federal sources cover about $31.4 million. State funding adds another $1.45 million. The city's share lands at $21.27 million — real money, but well under half of a project of this scale, and the sort of leverage that only shows up when a local corridor plan lines up with a state and federal priority at the same moment.
The build itself is a five-lane road with sidewalks and multi-use paths along its length, plus the interchange that ties it into the interstate. That combination matters. A five-lane arterial with no pedestrian provision is a wall through a neighborhood; the same road with sidewalks and a parallel path is at least a seam.
The traffic problem it is meant to solve
Anyone who drives Northwest Broad Street or Thompson Lane at the wrong hour already understands the case for this project without needing a study to explain it. Those two corridors have absorbed decades of growth on the city's northwest side, and both of them carry traffic that has no other reasonable way to go.
The Cherry Lane Extension is designed to give that traffic somewhere else — a new east-west corridor connecting areas on either side of the interstate, with a direct on-ramp instead of a long detour to an existing interchange. In practice, that should peel a meaningful share of trips off Broad and Thompson before they ever reach the congested stretches, rather than trying to widen a road that is already boxed in by everything built along it.
A piece of a much larger map
This approval does not stand alone. Murfreesboro has been assembling an unusually ambitious roadway program in recent years, with hundreds of millions of dollars in improvements queued across the city — corridor plans, extensions, widenings, and interchange work that only make sense when you look at them as one network rather than a list. Our running update on the city's major road projects lays out how the pieces fit, including where Cherry Lane sits in the sequence.
The I-840 corridor in particular has become the city's growth frontier. Industrial and commercial development has followed the interstate's arc, including a 167-acre business park planned along the same corridor. Access drives that kind of investment, and new access tends to generate more of it — which is exactly why the sidewalks and multi-use paths written into this design are not a decorative afterthought.
What happens next
Signing an agreement with the state is the step that unlocks the rest: design finalization, right-of-way, utility relocation, and eventually a construction contract. Roadway projects of this size are measured in years, not seasons, and the orange barrels are not going up next month.
But the decision that determines whether a road gets built usually happens in a council chamber long before anyone turns dirt. That decision has now been made.
