The Northern Link, Sweden
ENHANCING STOCKHOLM’S HIGHWAYS ENVIRONMENT
Stockholm’s new northern city link road will connect Sweden’s major
freight harbours and ferry terminals serving the Baltic states, Finland
and Russia.
Currently in the planning phase, the 13 km northern link is mainly
tunnelled. It is intended to relieve the heavily congested city centre
streets, whilst also benefiting city dwellers and road users through
the introduction of environmental measures such as reduced noise
and NO2 emissions.
WSP’s contracts on this extensive project include design of all the
link’s systems installations, including power, ventilation, drainage,
lighting and fire alarm systems. Underground electrical power
installations, pumping stations, evacuation routes and fan rooms
all meet stringent standards to ensure a safe and efficient highway
environment for road users.
These installations are in three classes:
■ Basic installations such as power, ventilation, water, waste water
and lighting;
■ Traffic management installations, such as road and lane signage;
■ Tunnel safety installations, such as fire alarm systems, CCTV and
emergency intercoms.
WSP is participating in all these projects and has prepared the overall
safety concept and fire safety strategy for the link, conducting risk
assessments, hazardous goods transportation reviews and evacuation
surveys for the tunnels.
WSP also prepared the tendering documentation for a contemporary
traffic management system including detection systems, automated
booming systems, signage and signals.
