A contractor, working on behalf of Boston Properties, owner of the Prudential Center,
is continuing ceiling repairs in the Prudential Tunnel (both directions). Completion
of that project is imminent. The most recent repairs are focused on the Eastern end of
the tunnel.
A contractor is also preparing to remove the ceiling in the portion of the Prudential
Tunnel (both directions) that passes under the Hynes Convention Center.
A contractor is surveying soil settlement around the I-90 Connector Tunnel near

the latest survey.
