a larger terminal on the Castle Island site, later named the Paul W. Conley Container Terminal, which opened in 1984. Massport dredged the entrance channel to a depth of in the mid-1990s. Today, the facility is capable of handling Panamax and post-Panamax container ships. As of 2019, Massport is expanding the facility westward into an adjacent brownfield site once used for oil storage, and has built a new entrance road. In November 2019, it received a $20 million grant from the U.S. Department of Transportation for additional improvements. In calendar year 2018, the terminal handled over 298,000 TEU's, up from 237,166 in 2015. Volumes have dropped dramatically due to the Covid-19 pandemic, but are expected to rebound as supply chain problems resolve and additional carriers serve the port. In June 2021, the terminal received three new ship-to-shore container cranes built in China, including two that are 205 feet high. In June 2022, the US Army Corp of Engineers completed a $350 million dredging project that will allow post-Panamax ships to dock without waiting for high tide. The CSX railroad's double-stack container terminal in Worcester is an hour and half drive from the terminal. The improvements resulted in additional shipping routes tripling the number of ports that ship goods to and from Conley. The state has proposed extending Track 61 to connect Conley to the national rail network, to eliminate this as a competitive disadvantage compared to other East Coast ports, however land for a container to rail terminal nearby would be difficult to find and current rail clearances do not allow double-stack operations. Boston Autoport (Charlestown) - Now dedicated exclusively to the processing and shipping of automobiles, this site once served as the common-use Moran Container Terminal. Boston Fish Pier (South Boston) - The oldest continuously operated fish pier in the United States, this facility houses companies dedicated to the processing and shipment of seafood. Non-Massport facilities The Port of Boston has facilities dedicated to bulk cargo, petroleum, and LNG shipment and storage. These are primarily located on the Mystic River, notably along the city of Everett waterfront as well as the Chelsea River area of East Boston, Chelsea, and Revere. The Chelsea River depots also contain facilities handling jet fuel for Logan International Airport.
