The biggest project in Thompson's Station history is officially on the way, and it's about 9 miles up the road from Spring Hill City Hall, roughly a 15-minute drive without traffic.
Sagefield is a 100-acre shopping, dining and entertainment destination from Simon Property Group, the company behind Opry Mills and The Mall at Green Hills. It sits at 1733 Lewisburg Pike, just south of I-840, and the town's planning staff report puts it at 496,366 square feet across 16 buildings.

What it means for Spring Hill
- Lewisburg Pike gets rebuilt first. Sagefield can't open until Lewisburg Pike becomes a four-lane state highway along the corridor and the I-840 westbound off-ramp gets more capacity.
- Expect more cars. The project is projected to bring about 14,681 new trips a day, and it's designed to pull shoppers from 35+ miles out, per the staff report.
- A big shopping option closer than Cool Springs. From Spring Hill City Hall, it's about 9 miles to Sagefield, versus about 22 miles (roughly 27 minutes) to CF Galleria at Cool Springs.
- Target opening: 2028, according to the Nashville Business Journal. That's tentative.
What's actually planned
The approved plan is mostly retail and restaurants, plus an event venue and maintenance buildings. Simon says Sagefield will be a "boutique retail, dining, hospitality and entertainment destination."
Earlier, Simon reps told residents to expect 70 to 80 shops and restaurants, along with walking trails, a pond and green space.
Land on the south end is set aside for later. That could include a boutique wellness hotel with a spa, pool, tennis and pickleball courts, and family restaurants.
A May 2026 agreement between the town and Simon describes an approximately 100-room boutique hotel with a spa and tennis resort, plus room for more buildings on outparcels.
At the November 2025 meetings, Simon reps said Sagefield could include specialty grocers and entertainment venues. Simon also announced plans for an organic market, farm-to-table restaurants and a members club.
The hotel side was announced with Sam Fox's Author & Edit Hospitality. Fox is the restaurateur behind Flowerchild in Franklin. Architecture firm Gensler appears on the design sheets along with Simon and Bohler.
No stores have been named yet. We'll update this as soon as tenants are announced.

Parking is planned at about 2,077 spaces, including 42 with EV chargers, plus 206 bike parking spots. The site will have three new traffic signals on Lewisburg Pike, plus one right-in, right-out entrance.

Jobs, a police station site and a target opening
- About 3,000 jobs. That's Simon's estimate from the November 2025 meetings.
- Land for a police station. Thompson's Station doesn't have its own police department. Mayor Brian Stover said at the Oct. 13 meeting that the developer is donating land on the site for a future police department.
- Groundbreaking in late 2026. At the November 2025 meetings, Simon said it planned to break ground in late 2026 and open in fall 2028.
- One opening day. Town staff said Simon wants all the stores to open together, and none of them can open until the road work is finished.
From outlet mall to "lifestyle" center
When Simon first announced the project, it was pitched as a 325,000-square-foot outlet mall.
After feedback from tenants and the community, Simon reworked it into a higher-end retail and entertainment destination.
The team changed too. AJ Capital Partners was originally Simon's partner. In October, AJ Capital exited the project, leaving Simon as the sole developer. Simon also bought the 100 acres for $32.5 million.
How the roadwork gets paid for
The land has been zoned commercial since 2008, so Simon didn't need a rezoning. Here's the timeline:
- June 23, 2026: Planning Commission approves the site plan.
- Sept. 24, 2026: The town's economic development board approves a financing agreement.
- Oct. 13, 2026: The Board of Mayor and Aldermen approves the deal 4-0. Alderman Bob Whitmer made the motion and Alderman Harry King seconded it.
Under the deal, Simon finances and builds about $42 million in road and sewer upgrades. The interest rate is capped at 8%. Simon gets paid back with half of the town's share of the new sales tax Sagefield generates, for up to 29 years. According to town staff, state and county sales taxes, including the part that goes to Williamson County Schools, are untouched.
Town staff also noted that Lewisburg Pike isn't in TDOT's 10-year plan. Without this deal, the widening was likely more than a decade away.
Here's what the money covers, according to town staff at the Oct. 13 meeting:
- Widening Lewisburg Pike from two lanes to four, with turn lanes
- Moving utilities along the road
- A new wastewater connection line
- Space for public safety
- Public plazas, walking paths and public art
Road and utility work makes up about 80% of the cost. Simon is building about $61 million in public improvements in total, and the $42 million deal covers part of that. The town and Simon will review the deal every quarter.
The plans also call for a 10-foot multi-use path on the east side of Lewisburg Pike and sewer work on Critz Lane.
Neighbors are worried about traffic
Traffic has been the top concern from the start. At a public meeting, Williamson County Commissioner Betsy Hester called the Lewisburg Pike and I-840 interchange "dangerous" and said it was never designed for today's traffic.
"Where are you going to put 25 or 30,000 cars?" one resident asked Simon reps.
Not everyone is opposed. One commenter on the Williamson Herald story said they had "mixed emotions." The commenter argued that traffic is already bad across Franklin, Spring Hill and Columbia, and that Sagefield won't change that.
Others have told NewsChannel 5 they worry about losing the area's rural character.
Simon development president Mark Silvestri told the crowd, "We recognize we're visitors, not residents," and said the company is confident its road improvements will address the traffic.
What town leaders said
Thompson's Station leaders addressed the traffic worries head-on when they approved the deal, according to the Oct. 13 meeting minutes.
Mayor Brian Stover acknowledged the backups around the amphitheater just east of the Sagefield site. "We did mess the traffic up a little bit. First Bank Amphitheater is a little bit of a mess, and I'll go ahead and tell you that right now. It is a mess. It is our job to fix it," he said.
Vice Mayor Shaun Alexander said he hears from both sides. "Frankly, I've heard a lot of people say they're excited about not driving to Brentwood to shop," he said.
He also pointed to the order of the work. Simon has to "complete it and then dedicate it over to the Town and under a warranty phase before they're allowed to even open their doors," Alexander said.
The town's own traffic study found that six of the 14 intersections it studied already had substandard conditions. Those are the spots the required roadwork is meant to fix.
