Dorchester Avenue (Boston)
street in Boston, Massachusetts, US
Dorchester Avenue (sometimes called Dot Ave) is a street in Boston, Massachusetts, running from downtown south via South Boston and Dorchester to the border with Milton, where it ends. Built as a turnpike, the Dorchester Turnpike, it is mostly straight.
History
The Boston South Bridge over Fort Point Channel, on the site of today's West Fourth Street Bridge, opened on October 1, 1805 as the first bridge connecting downtown to South Boston. Until it was sold to the city of Boston on April 19, 1832, it was a toll bridge.
The Dorchester Turnpike Corporation (sometimes called the South Boston Turnpike) was created by the state legislature on March 4, 1805, to build a turnpike from the east end of the Boston South Bridge (Nook Point) to Milton Bridge over the Neponset River, on the other side of which the Blue Hill Turnpike later continued.
Construction cost more than expected, and thus high tolls were charged, so many travelers took the old longer route through Roxbury. Despite that, the Dorchester Turnpike was one of the most profitable turnpikes, with earnings steadily climbing to a peak in 1838. When the parallel Old Colony Railroad opened in 1844, earnings quickly fell.
The North Free Bridge, on the site of today's Dorchester Avenue Bridge, opened in 1826, providing a more direct route form the north end of the turnpike to Dewey Square downtown.
On April 22, 1854, the turnpike became a free public road, named Dorchester Avenue.

Why this record matters
“Dorchester Avenue (Boston)” is worth following because a concise public description often conceals a longer documentary argument. Here, Dorchester, Avenue and Boston provides the most credible route into that argument.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Sep 15, 2026. The linked authority identifier is Q5297597. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1805, 1832, 1838 and 1844.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
