All four traffic lanes on the Bourne Bridge have been reopened following a weeks-long steel repair project, the U.S. Army Corps of Engineers, New England District has announced.

Steel repair work will continue below the road deck on the Bourne Bridge until the fall of 2012, resulting in occasional one-day lane restrictions during the next couple of weeks and through the fall of 2012.

The $8.5 million Bourne Bridge and Sagamore Bridge repair project involves the removal and replacement of structural steel secondary members, the strengthening of existing structural steel members, the replacement of structural fasteners, the removal of selected existing welds, and the strengthening of selected gusset plates. The Sagamore Bridge is also set to undergo repair. Above-deck work will begin after winter and continue through the fall of 2012. Temporary lane restrictions, reduced to one lane in each direction, will be put into place in the spring of 2012 for about four to six weeks.
