The five Green Line branches were lettered in 1967, with the Huntington Avenue line designated the E branch. In 1968, the city and the MBTA began planning a widening of Huntington Avenue east of Brigham Circle. Three of the eight stops (Forsyth Street, Vancouver Street, and Wigglesworth Street) would be closed, with platforms widened (the original impetus for the project) at the remaining five. The long siding would be moved inside the reservation, and fencing would be placed between the tracks to deter pedestrians from crossing the tracks away from intersections. The project was stalled in 1969 by federal budget cuts. In 1971, the MBTA replaced both tracks between Brigham Circle and Parker Hill Street. The widening project was revived in 1972, with the addition of a footbridge at Northeastern. The project faced opposition from the Museum of Fine Arts, which objected to the taking of a -wide strip of the museum's lawn. It was placed on hold in 1975 due to the ongoing recession.
