A semi hauling crushed cars struck the underside of the I-81 bridge at Exit 23 in Mosheim Wednesday morning. Police say the scrap metal load exceeded the 14-foot-6 clearance and violated multiple transport rules. Fuel spilled from a crushed vehicle, and the load was unsecured. The bridge sustained scrapes but no structural damage. The truck later scraped the bridge again from the opposite direction. Citations are pending following inspection by state troopers.
