The S.C. State Ports Authority inland port in Greer is slotted to begin operations on Oct. 14, an official said today.

The 100-acre intermodal terminal was initially scheduled to open in September, but development was delayed due to more than 72 days of rain, SPA officials have said.

Matt Tomsic, a spokesman for the maritime agency, said Oct. 14 will be a “soft opening” for the facility that sits near Greenville-Spartanburg International Airport.

The inland port will allow shipping containers to be transferred between trucks and Norfolk Southern rail cars running to and from the Port of Charleston, some 220 miles away. It’s expected to take tens of thousands of trucks off of state roads and highways each year.

The $48.6 million project is a shared expense between SPA and Norfolk Southern.

The port is part of SPA’s billion-dollar program to update and add new facilities over the next decade.

The plan comes as SPA looks to propel South Carolina’s market share in the shipping industry, an effort that includes work under way to deepen Charleston Harbor so it can accommodate larger container ships once the expansion of the Panama Canal is completed in 2015.
