Subways Construct Plan With Steel Arched Tunnels
The commission chooses steel embedded in cement for subway construction, replacing masonry arches due to instability under lateral pressure and cheap steel. Plans fix eight at fourteen feet, two tracks at twenty four feet, four tracks at forty eight feet, with central steel columns. The route runs from Shawmut and Tremont to Park Street, with a branch along Boylston and the Common to Charles Street, and under Tremont to Scollay Square. Platforms are island type, 150 feet long, with protected access and no at grade crossings.
