Cairo Metro Line 3-Phase 4B Viaduct
		

				

				

				

							
Project Overview:
Phase 4B of the Cairo Metro Line 3 project represents a significant expansion of Cairo’s public transportation network. This phase specifically focuses on the construction of an elevated viaduct section, extending the metro line and connecting previously underserved areas. This elevated section was crucial for navigating the specific urban landscape of this part of the city, offering a cost-effective and efficient solution compared to further tunneling. Phase 4B is part of a larger effort to improve connectivity and reduce traffic congestion in the Greater Cairo area.
						

				

					

		

					

		

				

						

					

			

						

				

																										

				

					

		

				

			

						

				

					

			

		

				

				

				

				

										

																					

										

							

				

					

		

					

		

				

						

					

			

						

				

					

			

		

				

				

				

				

							
Key Components:
Phase 4B of the Cairo Metro Line 3 project includes the following key components:
  • Elevated Viaduct: A significant length of elevated track structure to carry the metro trains.
  • Six Elevated Stations: These stations provide access to the metro line for residents and commuters in the areas served by this phase.
  • Supporting Pillars/Structures: The robust infrastructure required to support the elevated viaduct and stations.
  • Integration with Existing Lines: Seamless connection to the existing underground and at-grade sections of Line 3.
  • Associated Infrastructure: This includes signaling systems, electrical systems, and other necessary elements for the operation of the metro line.
						

				

					

		

				

			

							

		

					

		

				

						

					

			

						

				

					

			

		

				

				

				

				

										

																					

										

							

				

					

		

				

			

						

				

					

			

		

				

				

				

				

							
ECPC’s Scope of Work:
ECPC provided 848 prestressed beams—a first for Egypt—for the six elevated viaduct stations of Phase 4B. These beams have an average span of 30 to 40 meters and weigh between 75 and 120 tons.
