WHAT IS AN AQUEDUCT? An aqueduct carries water which usually flows by gravity. The aqueduct structure carries water smoothly across a valley or river. Aqueducts can be found in ancient civilizations; the Romans used aqueducts to carry their water from the mountains to their cities.
CANAL AQUEDUCT - The water in this aqueduct carries water from the Delaware Canal across the Tohickon Creek. Water flows through this portion of the canal for the first time in 20 years. This 200' structure is the longest of the ten aqueducts on Pennsylvania's Delaware Canal. The structure is the only canal made of a wooden structure; most of the other aqueducts are made of concrete.
It took more than one year to restore the structure. It replaces a structure that was condemned and closed to the public for years. The aqueduct was rebuilt completely from wood and is similar to its original construction of 1832.
The made to order structure was pre-cut and pressure treated. A rubber lining (not like the all wooden original) was covered with wood above and supported by wood below. The rubber lining will prevent water from seeping through the wooden support structure, freezing, and expanding the cracks.
