Crossing the Severn
Objectives :-
To describe how people and
animals have crossed the river
Severn in the past and present.
To create, design and build an
innovative way of crossing the
Severn.

Under and Over
Under and Over - Tiny water voles
burrow under the reens that drain the
forgotten landscape and the
two Severn crossings carry thousands
of people over the Severn every day.
Starlings and sparrowhawks get a
birds’ eye view of the estuary while
fossils lie just underneath its surface.

Make your Severn crossing
You are going to design and make a new
innovative way to cross the river Severn.
You need to use the materials provided to create
a model of your design. Your model must be able
to support the lego man across the river.
When you have you model come back and test it.

Your design
Look at the following slides and take inspiration
from designs from the past, present and future.
Think about whether you will go under or over
the river, whether you will use the water or try to
keep dry.

The Severn Bridge is a
suspension bridge,
carrying the M48 across
the river Severn and river
Wye. It leaves Aust and
arrives in Chepstow, via
support in Beachley on a
peninsula. The bridge
replaced the Aust ferry in
1966, and was granted
Grade 1 listed status in
1999. The bridge spans
1.6km and is 136m high.

Second Severn Crossing
The Second Severn Crossing carries the M4 motorway across the river Severn from
England to Wales. To the north of the bridge is the River Severn and the south is the
Severn estuary. Spanning over 5km and 137m high, the bridge’s central section is a
cable stayed bridge while the approaching viaducts are segmental bridges. It was open in
1996 to relieve congestion on the original Severn Bridge.

Severn Tunnel
The Severn Tunnel was opened in
1886 to allow the Great Western
Railway trains to continue their
journey from London to Wales. The
tunnel travels 3.6 km under the River
Severn, although the whole tunnel is
over 7 km long. Trains spend about 3
½ minutes in the tunnel

Aust Car Ferry
The Aust ferry carried cars across the river Severn between Aust and
Beachley from 1926 until 1966 when the Severn Bridge was opened.
The mile boat trip saved cars the 60 mile trip up to Gloucester which
was the quickest alternative route into Wales. The ferry operated
between two small piers at Old Passage and Beachley and the service
stopped at high and low tide.

Severn Tidal Barrage
Barrages across the river Severn have
been proposed since the 19th century.
Different ideas have included creating a
harbour, preventing floods and more
recently generating electricity. It has been
estimated that a 10 mile barrage across the
river Severn would generate 5% of the UK’s
electricity needs, with no carbon dioxide
emission once it is up and running.
However currently there are no plans to go
ahead with a barrage, which costing
between £10 and £34 billion, is not
considered economically viable.

Birds Pilning2 by A Forgotten Landscape
Migrating lapwings crossing the
Severn
These lapwings have flown across
the Severn from Germany and the
Netherlands to spend the winter in
the south west of England. These
wading birds are in decline in due to
the draining of the land for intensive
farming so the Severn estuary is a
perfect place for them to winter.

Inspiration from the man-
made and the natural
environment
Use the pictures and photographs on the desks
as inspiration, to think about unusual ways of
crossing the Severn.
