China to Savannah Shipping Guide
China to Savannah Shipping Guide
Savannah deepened its channel to 47 feet in 2022 and still cannot take every ship that wants to call, because the constraint was never only the water. The harbour is deep; the bridge above it is not.
Asset | Figure | What it means for importers |
Channel depth | 47 feet at mean low water, up from 42 | Larger vessels can transit without waiting for tide |
Tidal range | About 7 feet | Depth reaches roughly 54 feet at high tide |
Talmadge Memorial Bridge clearance | 185 feet above mean high water | Caps vessel size; larger ships depend on tidal and load windows |
Garden City Terminal | Single contiguous terminal on the Savannah River | Concentrated handling; one gate complex |

The deepening, and what it bought
The Savannah Harbor Expansion Project deepened 40 miles of the Savannah River from 42 feet to 47 feet at mean low water. Dredging began in September 2015 and the project was marked complete in March 2022, at a cost of approximately $973 million.
The gain is not only depth. A deeper channel removes the need for vessels to wait for high tide to enter with a full load, which expands the number of hours in which a large ship can transit. The Georgia Ports Authority estimated the additional depth allows roughly 1,000 additional containers per vessel.
The economic case was built on removing tidal dependency rather than on accommodating larger ships alone. A vessel that must wait for high tide loses a window at the berth, and the loss propagates through the terminal schedule.

The bridge is the real ceiling
The Talmadge Memorial Bridge, built in 1991 and about 1.9 miles long, provides approximately 185 feet of vertical clearance above mean high water. That is sufficient for vessels in the range of 16,000 TEU and above, but the margin depends on the ship's load, the tide and the bridge clearance acting together rather than on any one of them alone.
The comparison that makes the point is New York, where the Bayonne Bridge was raised to 215 feet specifically to remove this constraint. Savannah has no equivalent fix in place, and a state study has examined alternatives including a new bridge at 230 feet. For an importer, the practical consequence is that the very largest vessels may not call, which affects the number of direct services rather than the depth of the channel.
This is why the port continues to study the crossing. A new bridge at 230 feet has been identified as one of the feasible long-term alternatives, and until something changes, the bridge and not the channel determines which services can be offered.

Why Savannah grew
Two structural features explain the growth. The first is Garden City Terminal, one of the largest single container terminals in North America, which concentrates handling in one place rather than spreading it across several facilities. The second is inland rail reach: Savannah has direct rail connections to Atlanta, Memphis and Chicago, which places a large share of the Southeast and lower Midwest within a single rail leg.
The port handled about 5.6 million container units in 2021, an increase of roughly 20 percent over 2020, and ranks as the fourth busiest container port in the United States.
The single-terminal structure is a double-edged asset. It concentrates labour and equipment where they are needed, and it also concentrates congestion, which is why gate appointment discipline matters more here than at a port spread across several facilities.
The growth also reflects a deliberate capacity programme. The port has been expanding terminal capacity in a series of phases that run ahead of demand rather than behind it, which is unusual among U.S. gateways and shows up as shorter dwell during peak.

Transit and routing
All-water services from China reach Savannah through the Panama Canal in roughly 28 to 32 days. As with any East Coast port, the routing choice available to an importer is governed by which strings the carriers operate, and the Suez alternative runs longer.
For an importer distributing to the Southeast, Savannah's advantage is that the inland leg is short and the rail connections run in the right directions. For cargo destined for the Northeast, New York is usually the better answer, and for the Gulf, Houston is.
The Southeast manufacturing base is the second half of the argument. Cargo that is both imported and exported through the same region benefits from a port that serves both directions, and Savannah handles a substantial export volume alongside imports.

Four things to check before booking
1. Which terminal the service calls, and whether the vessel size is compatible with the bridge clearance on the planned tide.
2. Whether the inland destination is served by rail from Savannah or requires a truck leg that erases the advantage.
3. The gate appointment lead time during peak season, which is the binding constraint once volume rises.
4. The empty return arrangement, since equipment pools differ from those at other Southeast ports.
