Light Portal : Boston Architecture

Massachusetts Public Realm Project by James Carpenter Design Associates (JCDA), USA

Light Portal Boston

Date built: 1995-2007

Design: JCDA

Location: Boston, MA, USA
Client: Central Artery Tunnel Authority, Boston
Architect of Record: Childs Bertman Tseckares
Engineer: Bechtel/Parsons/Brinkerhoff

As part of the positive urban transformation placing Interstate Highway 93 underground, the Light Portal marks the datum line through which the nine lane highway descends from the Zakim Bridge into the Central Artery Tunnel. JCDA designed a shaped concrete retaining wall from which five hundred metal fins coated with a printed micro prism film reflect light back to its source.

This phenomenon makes each fin glow under low light conditions and luminously react to the headlights of the cars entering and leaving the tunnel. This phenomenon primarily highlights the paths that connect pedestrians to the Charles River, Boston Harbor and Boston’s Greenway while simultaneously heightening the experience of transition experienced by the motorists.
