new office block is constructed on the south side of the Liffey in
Dublin Ireland. The DART rail system crosses the bridge on this side
of the office block. DART started in 1984, originally carrying 35,000
users each day. It now carries 80,000 commuters each day and is forecast
to grow until 2016. The service is being extended as part of an effort
to promote sustainability in a city which had had an unforeseen explosion
in car ownership which has produced up to 1000 extra cars each week
on the streets of Dublin.
