The Jacobs/APPM/Posad
consortium launched their solution for an alternative public transport
connection, bridging the two communities of Amsterdam and Almere. The
Consortium proposes a rapid regional metro line – the Nieuwe Lijn – between
Amsterdam Isolatorweg / Sloterdijk and Almere Oost, fully integrated into the
existing metro Ringlijn. The capital cost of the construction of the Nieuwe
Lijn, are 2,6 billion according to Dutch standards. We estimate the capital
cost at under €2 billion, is less than half that estimated in the original
reference case. The line is also expected to generate considerable extra demand
and takes the pressure and future investment of the existing Hollandse Brug.
The deficit in the business case has been reduced by 86% from € 3,8 billion to
€ 0,5 billion euro.Combine Public Transport and Urban DevelopmentThe Nieuwe Lijn
provides more than just an additional piece of infrastructure. The scheme
merges urban development in Amsterdam and Almere with new and existing public
transport systems and operations (Transit Oriented Development).The Design and Spatial ConceptThe new
infrastructure had a number of challenges to address including the crossing of
the Amsterdam-Rijn kanaal, the contaminated land at Diemerzeedijk and, of course
the crossing of the IJmeer itself. The design proposed by the Consortium is
both attractive and functional with each element reinforcing the distinct
identity of the new line. The IJmeer will be traversed by four cable stayed
bridges that will link three new artificial islands, which is expected to
reduce the overall cost of construction also, add to the ecological development
of the region. The integration of spatial and environmental development with
design is a key feature of the proposal. These new islands will provide
ecological and amenity value to the IJmeer through the creation of new
habitats. The addition of a new peninsula and a new marina on the western edge
of the existing Pampus will create Almere Pampus Bay which will support the
development of water based recreation.
The design also
recognises that in residential areas special care needs to be taken with the
design to ensure the integration of the line into the existing urban fabric,
for example at IJburg the track will be built on an embankment and a linear
park will be developed above the tracks.New residential and employment areasThe business case is
further enhanced through amending and integrating existing and developing new
proposals for urban development in Almere and Diemen. The consortium proposes
to develop a new interchange for the Gooi-line and De Nieuwe Lijn. This will
enable the development of new, high quality residential and employment areas
around New Diemen and the existing settlement of Diemen. This intervention should
also help to improve the currently fragmented urban structure of Diemen.
As a result of the implementation of the consortium’s plans it is anticipated
that land development values will be enhanced through reducing the allocated
IJland residential area which is adjacent to Almere Pampus whilst
simultaneously creating high quality urban and green space networks. The
appealing spatial design is realistic and also marketable. Two new stations
will be realised in Pampus and in Almere, residential and other development
will complete the improvements of Almere Mondriaan station and at the terminus
at Almere A27 station to the east of AlmereThe Way ForwardThe Nieuwe Lijn
offers a flexible solution creating significant additional capacity in a cost
effective way. It is expected to stimulate sustainable urban development and
reduce the pressure on urban sprawl within the metropolitan region. The Nieuwe
Lijn could also serve as a blueprint for the development of the public
transport network within the metropolitan region. This provides an attractive
way forward for the future development of the region.Read more
