In the quiz thread, I promised a full listing of the highway ventilation buildings in Boston. There are 13 ventilation buildings, one air intake, and three fan chambers. Images are from Street View, with a few of mine mixed in.
Ventilation Building 1
is on Dorchester Avenue next to Rolling Bridge Park. It is the west structure for the Fort Point Channel Tunnel.
Ventilation Building 3
is in fact the east core of the Intercontinental, on Atlantic Avenue at Pearl Street. It serves the Central Artery. No sign of its ventilation use is visible from ground level.
Ventilation Building 4
is at Haymarket Square and serves the Central Artery. The structure includes a parking garage, the RMV, the Boston Public Market, and the south headhouse of Haymarket station. Unlike Building 3, the vent stacks are clearly visible.
Ventilation Building 5
is on Summer Street opposite the BCEC, at the east end of the Fort Point Channel Tunnel.
Ventilation Building 6
is on Fid Kennedy Way at the south end of the Ted Williams Tunnel.
Ventilation Building 7
is on Harborside Drive at the north end of the Ted. It's the largest of these large structures - 380 feet long and 140 wide - and won a couple of design awards.
Ventilation Building 8
is tucked between the North Station platforms, the Leverett Circle Connector bridge, and the Zakim bridge and a southbound onramp.
Ventilation Building 10[url] is on North Street near the Boston end of the Sumner Tunnel.
Its twin, [url=https://email@example.com,-71.0411389,80m/data=!3m1!1e3]Ventilation Building 11
, is on Liverpool Street in East Boston. (Liverpool Street, like several nearby streets, is named for the port city its docks once served ships to.)
Ventilation Building 12
is at North Street over the Boston portal of the Callahan Tunnel.
Its twin, Ventilation Building 13
, is on Decatur Street in East Boston.
Though barely a thousand feet long, the City Square Tunnel (CANA) has two ventilation structures. Ventilation Building 14
is on New Rutherford Avenue adjacent to some ghost ramps.
Ventilation Building 15
, at the corner of Warren and Chelsea, is designed to fit in with the nearby brick buildings.
The Dewey Square Air Intake
is well known on this forum for the murals it hosts.
Three fan chambers date to the 1950s construction of the Dewey Square Tunnel; a fourth was located in Dewey Square until the Big Dig. The Essex Street Fan Chamber and Summer Street Fan Chamber
flank Surface Road between their namesake streets,
The Beach Street Fan Chamber
is adjacent to Chinatown Gate. It was wrapped with this artwork about a decade ago.
