The following information was provided by MassDOT:
The Massachusetts Department of Transportation has announced that there will be various overnight impacts including lane closures on I-90 east and westbound as well as short-term detours of Commonwealth Avenue east and westbound in the area of the Commonwealth Avenue Bridge and the Boston University Bridge from Monday, July 22 through Saturday, August 10. These impacts will take place during overnight hours only and will allow crews to safely and effectively conduct scheduled construction operations on the Commonwealth Avenue Bridge. The impacts will vary depending upon the work being conducted, but in general, the I-90 lane closures will take place from approximately 9 p.m., through 4:30 a.m., and the Commonwealth Avenue detours will take place from 1:30 a.m., to 4:30 a.m.
As always, work is being conducted in ways that minimize impacts on the traveling public and local community. For example, operations are being conducted during overnight hours to prevent travel disruptions. These impacts are associated with the larger bridge replacement project and are necessary to conduct final scheduled construction activities per project plans.
