Propane business argues in latest Key Bridge filing that ‘an example should be made’ of Dali’s owner

Since 2017, train cars from as far away as Alberta, Canada, have carried propane and butane to Underwood Energy’s rail yard in Sparrows Point. There, the company transfers the gas onto tractor trailers bound for customers throughout the region, who use it to cook, heat or resell. Owner Sean Underwood told The Baltimore Sun that more than 70% of the trucks used to head south from his facility, a route that took them over the Francis Scott Key Bridge, until March 26, when the massive cargo ship Dali toppled the span.
