About Northern Avenue Straightening
Northern Avenue in Boston's Seaport District is being straightened to accommodate the buildout of Seaport Square and Fan Pier. As opposed to the current diagonal orientation, the new Northern Avenue will run parallel to Seaport Boulevard, intersecting East Service Road by 100 Northern Avenue. Northern Avenue's straightening will free space for new development at Seaport Square's Parcel G. Additional land at Parcel F will be freed to further expand Seaport Pavilion.
