Footpaths have been cut by the people —and their walking
has made them smooth.
Roads cannot be made that way. Who. makes them?
|Does the Federal Government look after all the roads,
just as it looks after the Railways?
hoe
No. There are many kinds of roads and they come under
different authorities.
Only some of the roads in the Western Region are federal.
Many more are regional or local.
The regional roads link the important towns, markets,
ports and centres of administration.
3The Public Works Department of the Western Region
looks after most of the roads in the Region.
It does all the work on federal and regional roads and
supervises the work on the more important local roads.
4PWD has a big tarring programme. Of the total mileage
of regional roads, only one-tenth was tarred before 1952
—
120 miles. Since then almost 300 miles have been added.

An even bigger programme of tarring has been planned
by PWD and will be continued.
5The more a road is used the more it will be affected by
heavy traffic.
If there is a soft surface, a lot of maintenance work will
have to be done, otherwise the road will soon become
dangerous to'use.
That is why PWD has a big tarring programme. Tar makes
the surface harder and rain-resistant.

The surface has to be repaired too. The cost is worth it.
ZLGood roads serve the whole population: everyone who
wants to sell his produce,
Everyone who wants to buy clothes, petrol or other
things which have to be carried,
8everyone who wants to export or import.

everyone who wants to travel.
9PWD takes a traffic census to find out which roads are
overcrowded.
On a special day several persons count the number of
cars that pass certain points.
10Then it may be decided that some roads should be wider
to carry more traffic.

Sometimes a new road may be suggested in addition.
iWhere a road enters a town, its traffic will interfere with
the town life.

It will be dangerous to both the people in the town and
the cars that pass through.
12The traffic can be faster and safer if it can avoid
the busy
centre of the town.

That is why by-pass roads are built. Town life will be
undisturbed too.
13Roads have to cross rivers and swamps and have to be
protected from rain erosion.
PWD lays culverts and builds bridges or renews and
widens them.
14It has to give specially strong foundations to the roads
which have to cross swamps.

WW wl,
Many more technical difficulties have to be solved and
new ways found to improve roads.
15PWD also puts up road signs so that every driver is warned
of dangers ahead.
In this, as in many other ways, PWD gives public service.
