Station design was 10% complete in March 2018 and 76% complete by that December. Construction began in mid-2019. By March 2020, the beams supporting the trackways and platform were being installed. The project requires a temporary service suspension while the elevated structure to the old station is replaced with the new viaduct. A bus shuttle between Lechmere and North Station – with dedicated bus lanes on the Charles River Dam Bridge – began on May 24, 2020, with the old station closed. At that time, service was expected to resume in April 2021.
