Acceso norte to Santiago
In 2014 over 18.5 million vehicles, including private, passenger and cargo vehicles, from both the surrounding areas and important production centres located in the north of the country, used Acceso Norte. Redevelopment of this 15 kilometres stretch is vital for improving movement for all road users.
Amongst its most relevant features, the Acceso Norte to Santiago will have four lanes running in each direction between the Quilicura Interchange, located at the intersection with the Américo Vespucio junction, and the Buenaventura interchange. From there the road will continue with three lanes up to the Lampa toll road where the route ends.
The works will provide continuation to the side roads, or service roads, between the Quilicura Interchange and the Lampa toll. At present these are interrupted by interchanges, including a road with two one-way lanes, cycle lanes and lighting.
For the purposes of environmental mitigation and operational control, the following options are being assessed: noise protection screens, security cameras to monitor both the state of the structure and the behaviour of the users, as well as building an operations hub where there will be vehicles to provide assistance in emergency situations.
To increase permeability and safety for pedestrians, the section between Santiago and Lampa will have 14 pedestrian walkways (10 of which are new). With the aim of increasing efficiency in terms of traffic flow, and also in the main section of the highway (Express Way), there will be 10 interchanges (six new, three remodelled and one already existing). One of these interchanges links with the Eje Lo Marcoleta project, which is also being built by FCC on behalf of the Housing and Urban Development Service (SERVIU), who report to the Ministry of Housing.
The Acceso Norte works will require 250,000 tonnes of hot mix asphalt and the creation of 50,000 m2 of MSE walls (reinforced earth). It is also worth highlighting the great difficulty in coordinating and managing the traffic resulting from the works. A highway operation will be fully maintained with the high volume of road users each year.
The works started on the central section of the route towards the northern section where they are managed. All of the service handling coordination occurs here including for activity located in the southern sector. This southern sector of the route is where the majority of the city's commercial and industrial activity takes place.
