The Linea Amarilla Highway involves the construction of an express highway across the city of Lima, connecting the Eastern and the Western part. This Peruvian megaproject that was approved in 2009 and has been started in 2012, is now shortly before the grand opening. Peru’s capital and with a population of 9 million the country’s largest city, can’t wait to profit from the new connection that leads through 11 districts of Lima.
The highway has a total length of 17 km including tunnels – one tunnel of length 1.8 km runs under the river Rimac – and approximately 9 km of viaducts. In total the structure includes 10 viaducts.
mageba supplied four TENSA MODULAR expansion joints for two viaducts - two of type LR6 and two of type LR7 (with 6 and 7 gaps respectively).
The largest of the expansion joints supplied accommodate longitudinal movements of 560 mm. The joints must also accommodate transverse movements of the same magnitude. Unusually for modular joints that must facilitate such large transverse movements, the joints also had to be equipped with noise-reducing sinus plates on their surface. These sinus plates thus required to be specially designed to allow the large transverse movements.
The joints were installed in December 2017, under mageba supervision.
