New Haymarket opened May 10, 1971
The lobby extends into the old station, and limited the available platform space during construction. For many years the remainder of the old station was lit and visible to passengers passing through. It was also visible to passengers on Orange Line trains, leaving or entering Haymarket, less so after 1975, when the tracks were shifted to the east.
IIRC, the center tracks through the station were out of service for many years, possibly since 1949. The switches to and from Brattle Loop were moved when the construction for the new station started. The present entrance is located at the south end of the platforms, about 25 feet south of the original entrance. When the new station first opened, the only access was from the passageway to the former Union-Friend Station - a long detour and not very popular.
The original entrance was located on an island in the middle of the square, where seven streets met. The three from the north, Merrimac, Canal and North Washington all point to the site of the head house. Sudbury and Blackstone were diverted away, and Washington and Union were replaced by an extension of Congress. The Government Center Garage sits atop the location of the island. The head house at Haymarket was rather plain, but those at Scollay and Adams were quite ornate.
