Early Roads and Bridges Via Appia (Appian Way) The Via Appia is the oldest paved road found in Europe. It was built by Censor Appius Claudius Caecus in 312 BCE Via Flaminia .The Via Flaminia ran from rome across the Apennine Mountains to rimini on the adriatic coast. It was built by Gaius Flaminius in 220 BCE By late republic paved roads connected all important areas in Italy Fact: Most of the roads were named from the person that constructed it.

Early roads and Bridges (Continued) Pons Sublicious- Built by Ancus Marcius in the 7th Century BCE First bridge across the Tiber Linked to major trade routes Facts The average width of a road was 12-15ft. wide (enough space for two legions to pass.) Some of the heaviest labor was done by slaves. Every legion had its own squad of surveyors and engineers.

Getting Started Surveyors chose a spot in the horizon or a large tree and build the road toward it.(If there was not a natural object that could be used they sent a soldier to light a fire and they would use smoke as a marker.) Every mile in the process of building a road was marked by a milestone. Milestone/Miliarium- A tall cylinder on top of a rectangular base that waset two feet into the ground but still stood high. Miliarium aurem- 12 foot column encased in bronze that marked all of the major cities in the empire Gromae- Used to ensure that two roads were intersecting at 90 angle.

Building Roads (procedure) Mark out the outer boundaries. Dig shallow ditch and place curbstones in them. Soldiers dug a trench about 4ft deep. Shovel a layer of sand in the trench. Roll over the sand to make it flat and cover it with a layer of finely cut gravel. Roll over the fine gravel and place the mixture of chunks of rocks which turned into concrete. Soldiers arranged paving blocks tightly .

The Arch An arch is a curved structure supported by to posts or columns. Could support very heavy weight. The romans invented concrete which followed the same formula as cement only they added pozzolana and some stone rubble. This made the arch stronger and able to support more weight. Arc de Triomphe

Famous Structures Pons Fabricius (Fabricius Bridge) oldest roman bridge still in use. Alcantara one of the finest roman bridges. Built 105 AD, 655 ft long and supported by six huge arches. Triumphal arch freestanding arch it was a symbol of power and victory. this arch was topped/crowned with a entablature (a rectangular top)

Aqueducts A bridge used for travel of water instead of people. Latin for conveyor of water Depended on the force of gravity to deliver the water to where it needed to be. Early aqueducts were placed under ground to keep enemies from poisoning the water and to keep it from getting polluted. Pont du Gard

Aqueducts continued Pont du Gard helped to supply 20,000 tons of water to the city of Nimes daily. Every aqueduct led to a huge water tower called a castellum. Cloaca Maxima Romes first sewer that is still in use today. Barrel Vault series of arches used to form a barrel like roof.
