Sagamore Bridge lane closures begin By Adam Vaccaro Globe Staff,Updated April 12, 2021, 2 hours ago Email to a Friend The Sagamore Bridge will be down to one lane in each direction for several weeks.John Tlumacki/Globe Staff/file Ahead of what is expected to be a record tourism season on Cape Cod, the Sagamore Bridge was reduced to one lane in each direction on Monday for what could be weeks of maintenance on the aging canal crossing. Itâs the second time in three years that the bridgeâs owner, the US Army Corps of Engineers, has closed lanes on the bridge to take on around-the-clock spring maintenance and repairs. The lane closures will remain in place until contractors complete the work, which includes repairs on steel supports and lighting equipment. The Army Corps has not provided a set date for when that will be, except to say the project will be finished by Memorial Day â typically the launch of tourism season on the Cape.
