CLIENT: BARCELONA METROPOLITAN AREA (AMB)
The Barcelona Metropolitan Area commissioned Esteyco to prepare the study analysing alternatives for modifying the Quatre Camins junction, one of the most important in the Barcelona metropolitan system in the ambit of the final section of the River Llobregat valley. The Quatre Camins crossroads is a multi-level cloverleaf junction with the features of the road system built in the 1960s where its type made sense due to its location in the joining point of the N-II and the N-340.
With the putting into service of the AP2, A2 and B24 and with the expectation of new road connections in the area, this junction has become an obsolete infrastructure, completely over-sized for the current traffic it has to carry.
This situation, together with the appearance of the Quatre Camins FGC station, provides the opportunity to convert this ambit into a large inter-modal space in metropolitan mobility.
The study analyses the mobility scenarios in the corridor in the lower valley of the River Llobregat and suggests various proposals for converting the junction, considering new road sections and allowing the implementation of the tramway and pedestrian and bicycle routes.
