PORTLAND, Maine (AP)   Maine’s push to encourage trade with Europe and the North Atlantic is leading to a record rising in shipping containers moving through Maine’s only container terminal.

The Portland Press Herald reports that the volume of containers moving through the Portland waterfront’s International Marine Terminal has more than doubled in the past five years.

The value of imported and exported goods reached $502.7 million last year. Top exports include paper products and ammunition cartridges and top imports include frozen cod fillets.

Meanwhile, a plan for a waterfront cold-storage warehouse to maintain a relationship with Iceland shipping firm Eimskip hasn’t gotten off the ground. Neighbors oppose the plan due to its aesthetic impact.

Maine has spent tens of millions of dollars to update and expand the International Marine Terminal since 2009.
