howard m. sexton, a 70-year-old truck driver from new jersey, was killed in the southbound lehigh tunnel on february 21, 2018, when an electrical conduit broke free from the tunnel's ceiling and fell through the windshield of his truck, striking him in the head. in a preliminary report issued on may 1, 2018, the national transportation safety board revealed that a 10-foot-long section of conduit fell into the path of sexton's truck after the steel support system for the conduits, which were suspended from the apex of the tunnel arch directly over the travel lanes, failed. the tunnel had last been inspected in 2016, at which time an inspector found evidence of corrosion on several of the steel support straps.
