Trajan's Bridge

From Wikipedia, the free encyclopedia

Drawings of the still-standing pillars

Trajan's Bridge (Romanian: Podul lui Traian; Serbian: Трајанов мост, Trajanov Most) or Bridge of Apollodorus over the Danube was a Roman bridge, the first to be built over the lower Danube. Situated east from the Iron Gates, nearby the present-day cities of Drobeta-Turnu Severin, Romania and Kladovo, Serbia, it was built as a supply route for the Roman legions fighting in Dacia (see Dacian Wars). Its construction was ordered by Emperor Trajan. For more than a thousand years, it was the longest bridge to have been built, both in terms of total and span length.^[1]

[edit] Overlook

The structure was 1,135 meters in length (the Danube is 800 meters-wide in that area), 15 meters in width, and reached 19 meters in height (measured from the river's surface). At each end was situated a Roman castrum, each of them built around an entrance (crossing was posible only by walking through the camp).

Its engineer, Apollodorus of Damascus, used wooden arches set on twenty masonry pillars (made with bricks, mortar and pozzolana cement) that spanned 52-meters each. Nevertheless, it was built over an unusually short period of time (between 103 and 105) — one possible expalanation is that the river has been diverted during the construction works.

A Roman memorial plaque, 4 meters in width and 1.75 meters in height, commemorates the completion of Trajan's military road completion is located on the Serbian side facing Romania near Ogradina. It reads:

IMP. CAESAR. DIVI. NERVAE. F
NERVA TRAIANVS. AVG. GERM
PONTIF MAXIMUS TRIB POT IIII

Ruins on the Romanian bank

The text was interpreted by Otto Benndorf to mean:

Emperor Nerva son of the divine Nerva, Nerva Traian, the Augustus, Germanicus, Pontifex Maximus, invested for the fourth time as Tribune, Consul for the third time, excavating mountain rocks and using wood beams has made this road. (Note: Italics mark parts of the inscription that have ben destroyed by time and were deduced from context)

[edit] Destruction and remains

The bridge was destroyed by Aurelian, after the Roman Empire withdrew its troops from Dacia.

The twenty pillars could still be seen in the year 1856, when the level of the Danube hit a record low. In 1906, the International Commission of the Danube decided to destroy two of the pillars that were obstructing navigation.

In 1932, there were 16 remaining pillars underwater, but in 1982 only 12 were mapped by archeologists — the other four had probably ben swept away by water. Only the entrance pillars are nowadays visible on either bank of the Danube.
