One house west of where Union Street meets Route 6A in Yarmouth Port, a stone carries four characters and a year: B 4 1729. Four miles to Barnstable village, according to the Historical Society of Old Yarmouth.

A few minutes south, Route 28 has nothing carved in 1729. It has a bridge from 1935, a mini golf course whose season ends Sunday, and a building that used to have sea lions in it.

Ask somebody how they get from Yarmouth to Dennis. The road they name tells you which Mid Cape they carry around.

Four miles to Barnstable, carved in 1729

The milestone has company. Just east of Parnassus Book Service, almost across from the Yarmouth Port post office, a second stone reads G T T / BOSTON / 76 MILES / 1880. The historical society says it was never a stagecoach mile marker or a town line, and presumes George T. Thacher set it.

The road those stones sit on goes back further than either. The Cape Cod Commission traces the Old King's Highway to a Native American trail that became the main east-west road on the Cape's north side. It runs 34 miles from Bourne to the Orleans line, through seven towns and eight National Register Historic Districts. The state named it a Scenic Byway in 1992, and in 2021 the U.S. Department of Transportation made it a National Scenic Byway. The land along it north of Route 6 sits in the Old King's Highway Regional Historic District, created by a 1973 state law, which the Dennis Historical Society calls the largest historic district in the country, stretching from Sandwich to Orleans.

The name some Cape Codders called unpatriotic

Even that name had to be fought for. In 1920, the historical society writes, the General Court named the road "The King's Highway." Markers went up along it, and some Cape Codders objected because they thought the name was unpatriotic.

You're a 6A person if your Mid Cape includes:

  • Hallet's in Yarmouth Port, which the historical society described in 2022 as the old drugstore, "now a soda fountain and luncheon establishment."

  • The Captain Bangs Hallet House, a sea captain's house the society dates to around 1840 and places just off the Old King's Highway on the Yarmouth Port common. The society runs it as a museum today.

  • The Cape Playhouse in Dennis, built when Raymond Moore "moved an abandoned Unitarian meetinghouse" to the site in the 1920s, per the Dennis Historical Society.

  • The Cape Cinema, near the Playhouse just off 6A, which opened in June 1930 under a Rockwell Kent ceiling mural of about 6,400 square feet. CAI reported it was the largest indoor mural in the world when it was installed.

Sunday is the last putt

You're a 28 person if your Mid Cape includes:

  • The former ZooQuarium at 674 Route 28 in West Yarmouth, now the Whydah Pirate Museum. (That's this week's lead.)

  • The Mill Hill Club in West Yarmouth, in a building that started in 1924 as the Old Mill Tavern. The historical society says the club was "virtually closed since 2005," and the building came down in 2014, per CAI. We wrote in September about the night its ladies' room burned and the club opened anyway.

  • Pirate's Cove Adventure Golf at 728 Main St. in South Yarmouth, whose last day of the 2026 season is Sunday, Oct. 18. Fall hours are 10 AM to 7 PM, and the course notes that hours are weather permitting.

If 6A is the postcard, 28 can look like the road the Cape got stuck with. Its paper trail says it was built on purpose.

The road that had no choice

Until 1933, there was no way through South Yarmouth but Old Main Street. "Prior to that, all traffic went down Old Main Street as no other road existed," the historical society writes. In 1933 the town got a Route 28 bypass connected to Bridge Street, and the crossroads people now call Four Corners was, until then, Three Corners.

Route 28 was already a long road by then. When the New England states numbered their highways in 1922, the society notes, it ran from Sagamore all the way to Manchester, N.H.

A bridge from 1935, on borrowed time

Then there's the crossing. The Bass River Bridge that carries 28 from South Yarmouth to West Dennis dates from 1935, MassDOT says, and is the fourth bridge at that spot. MassDOT also says it's reaching the end of its useful life and has to be replaced. For now, it's a working piece of the 1930s you can still drive across.

So 28 has its own history, just a newer one: a bypass in 1933, a bridge in 1935, a replacement on the way. And 6A wasn't preserved in amber either. It got its name, and its markers, from the legislature in 1920, over some residents' objections.

Run the loop before Sunday

This weekend, while Pirate's Cove is still open (weather permitting), try it. Start at the 1729 stone in Yarmouth Port, one house west of Union Street. Take 6A east past Hallet's to the Cape Playhouse in Dennis. Then drop south to 28 and come back west over the 1935 Bass River Bridge, past the mini golf, to 674 Route 28.

Bring whoever in your house always takes the other road, and let them call the turns on their half. Then tell us which road you'd take home, and the one place on it that proves your case.
