This section of the High Speed Railway Line Valencia-Barcelona, parallel to the Mediterranean shore, crosses several valleys and roads.
This project includes 8 viaducts. All bridges allocate two tracks in a 42 ft (12.8 m) wide platform. The project includes a cast in place pre-stressed concrete viaduct with an overall length of 1339 ft (408 m) and with a main span length of 157 ft (48 m).
The deck was erected using a segmental procedure (span by span) and the typical cross-section is 9 ft (2.98 m). The maximum height of the piers is 72 ft (22 m). The rest of the viaducts were designed using two pre-cast pre-stressed concrete ‘U’ girders, 8 ft (2.5 m) high, connected to a 1 ft (0.3 m) top slab. The length of the viaducts varies from 98 to 787 ft (30 to 240 m).
The bridges were built using a launching steel girder for the segmental construction procedure (span by span). Due to the high weight of the deck, pre-stressing was applied in two stages. The procedure required minimal support and the system permitted to optimize reinforcing and pouring of concrete. The typical cycle operation was 14 days per segment 196 ft (60 m).
