As of Fall 2021, MassDOT and its Design Team are working to file a Notice of Project Change (NPC) and a joint Final Environmental Impact Statement (FEIS) and Draft Environmental Impact Report Statement (DEIS). The FEIS and DEIS will be filed with both the MEPA and NEPA offices of Federal Highway.
The NPC will reflect the agency's decision to focus on the Modified At-Grade Option. The NPC is expected to be published in Winter 2021. The Modified At-Grade, SFR Hybrid, and Modified Highway Viaduct will be analyzed in both environmental reports. We expect this work to run into 2022 and for the joint environmental report to be filed in Fall 2022. Construction is expected to begin in late 2023 or early 2024.
