The Massachusetts Port Authority on Oct. 13 reopened to commercial traffic two of three lanes of the upper deck of the 57-year-old Tobin Memorial Bridge after an Oct. 12 inspection revealed several small cracks and corrosion in a transverse floor beam. Colonial Steel, Carlisle, Mass., wrapped the beam in steel cables as a temporary fix. Angle plates will be welded or bolted to the beam and adjacent column by the end of the month. The 800-ft-long double-deck steel-truss bridge spans the Mystic River near Boston, carrying heavily trafficked U.S. Route 1.
