The Massachusetts Department of Transportation (MassDOT) will rehabilitate the I-93 Viaduct in Somerville between Exit 21 and Temple Street starting in Summer 2022.
Somerville I-93 Viaduct Preservation work will take place from Summer 2022 to Fall 2024. These necessary repairs and improvements will extend the life span of the Viaduct. Construction will begin in mid-June 2022. Periodic detours on local surface roads and highway ramps, as well as nightly lane closures on I-93 are required to complete this work.
