Abstract:
The combined bridge and tunnel link between Sweden and
Denmark (the Øresund Link) and the related land constructions
are expected to be in operation around the turn of the century.
This new link across the Øresund and the island Amager may
result in significant changes in traffic pattern and traffic
intensity - and therefore changes in air quality in some areas
can not be excluded.
An investigation initiated in 1994 on the Danish side of the link
comprises monitoring of present air pollution at the Airport
Motorway and model evaluations of future pollution levels at the
motorway and in six street canyons. For all locations the
pollution levels are calculated for the present situation and for
scenarios for the years 2000 and 2010 both with and without the
fixed link. For the future scenarios an expected development of
vehicle technology is taken into account. It appears that the
general air quality in the area will not be worsen. Only for
benzene there is a continued risk of violation of limit values;
this may however be changed by planned emission restrictions.
A special situation however, may arise near the apartment
buildings "Vinkelhusene". Here it has been decided to
cover about 700 m of the motorway, in order to reduce noise and
to avoid a barrier effect. This will result in increased
pollution levels near the tunnel exits.
All calculations are performed with dispersion models developed
at the National Environmental Research Institute and are based on
traffic scenarios from a traffic model developed by Anders Nyvig
Ltd.
