Lanes. Either 6 lanes with all 4 lanes motorways up gradable to 6 lanes as traffic on them increases.
Speed limit. 100 km/h for heavy transport vehicles and 120 km/h for light transport vehicles.
Separation limit. Pakistan's motorways have a UN broken central raised concrete median and grade separated junctions.
Access. Access to Pakistan motorways is restricted to fast moving vehicle only, including high performance heavy bikes. Pedestrian, bicycle, low performance motorcycle, animal driven carriages and other slow moving vehicle are not permitted on the motorways.
Fence covering. The motorways are fenced on either side for safety and prevention of unauthorized access by pedestrians, animals and slow moving vehicles.
Entry. There are a no of interchange points are the only points from where vehicles can enter or exit the. Motorway. These controlled interchange points are the only points from the where vehicle can enter exit the motorway.
Numbering. All motorway in Pakistan are pre fixed with the letter M for motorway followed by the unique numerical designations of the specific motorways..
The M-1 motorway Peshawar- Islamabad and the M-2 motorways Islamabad- Lahore each include two emergency runway section of 9,000 ft,length each.
Import motorways:
M-1 Islamabad Peshawar motorway. 135km long.
M-2 Lahore Islamabad motorway. 333km long.
The first motorway to be built in South Asia.
M-3 pindi battian Faisalabad. 54 km long.
M-9 super high way not yet in status. 138 km.long.
M-10 Karachi northern bypass. 57km long
The M-10 is the second shortest motorways in Pakistan's the shortest being M-3
The M-10 is actually a bypass diverging outbound traffic away from the Karachi and is the only by pass in Pakistan given the status of a motor way.

makran coastal highway
Makran coastal highways is a 653 km-long coastal highway was awarded along pakistan's arabian sea coastline.It runs primarily through balochistan between karachi and gwadar passing near the port towns of omara and pasni.
The construction contract for the makran coastal highways was awarded to pakistan's frontier works organization FWO, which built the karakoram highways.
Construction work pn the makran coastal highway project commenced in 2002 and was completed by 14 december 2004 in a period of three years.
The official and technical designation of the makran coastal highway is N-10.
The makran coastal highways was conceived and built by the goverment of pakistan with the following objectives.
to developinfrastructure and boost economic activity in the areas along pakistan's coastline
to improve the transportation and communications infrastructure in balochistan province.
to developed the coastal towns of ormara pasniand gwadar into major port cities.
to link ormara and pasni and gwadar with the rest of pakistan's national highways network
to developed the seafood industry along paksitan's coastline by reducing the ttime and costs involved in tranporting fresh seafood from seafood catchment areas to major cities in pakistan as well as export processing zones in karachi and gwadar.

THE USA;
The rise of the steel industry in the united states drove america's growth as a world economic power.Although iron works had been established in the north american colonies shortly after european settelment began,it wasn't until the 19th century when technological advances decerease the cost and increased the quality that steel manufacturing became a dominant industry.
With the abundant iron ore deposits around lake superior the rich coal veins of pennsylvania and the easy access to cheap water transportation routes on the great lakes the midwest became the centre of american heavy industry.In years after the civil war the american steel industry grew with astonishing speed as th nation's economy expanded to becomethe largest in the world.
MAJOR AREAS:
pittsburgh regions.It is the iron and steel capital of the world.

availability of water and large tracts of land
AVAILABILITY OF WATER AND LARGE TRACTS OF LAND;
Water is required for cooling and washing.Thus the neaness to a river lake or s coastal site has necessary for the industry .Large tracts of level land are also necessary for the iron and steel work as the various operation connected with the production of iron and steel cannot be carried on in a limited area.For example the steel mill of karachi covers an area of 18,623 acres of land.
TRANSPORTATION FACILITY;
Easy transport is required for moving bulky and cheap raw materials such as iron,ore,coal and limestone and for moving out the heavy manufactured good.
MARKET;
The producers of the iron and steel industry are the raw material for a number of subsidiary industries such as machine tools.Railway equipments engineering goods electrical goods and transport equipments etc.For the development of iron and steel industry subsidiary idustries are essential.
Energy/power; chapter-07unit-01 Coastal location; chapter-07 unit-01.
GLOBAL DISTRIBUTION;
Iron production is predominately in asia australiasia and north america.China had a production of 683million tons and japan's is 108 million tons.The US produces 86 million tons for others see the table.
The main producers are MEDCs but there is an increasing number of LEDCs e.g. china,india and brazil.This is due to cheap labour and more modern efficient factories.Markets are moving to LEDCs so factories are built nearer to them..
CHINA;
China has been the largest steel industries in the world driven by increasing demands for rapid urbanization and many large scale infrastructure project.In 2007 the country produced 495.
Millions tons of crude steel,recording a production growth of 15.7% from the previous year while the chinese consumption of crude steel reached 434.4 million tons rising by 11.9% from the previous year.
Raw material production in china recorded a 2% increase over a period of 110 years.In 2012 china's steel production is expected to touch715 million tons.Despite production production cuts,slackening demand and rising stock china's output for 2012 is expected to be 5.2% up to from 2011.
soils
CLASSIFICATION OF SOILS OF PAKISTAN;
It is aldo true that pakistan's soil can be classified regionally or according to where it is a formed is the country.From that persepective there are the folliowing soil types,
INDUS BASIN SOILS;
The indus plain is made with the depositions of alluvium by the indus river and its tributaries.For the last thoushands of years rivers have been depositing the soil in the form of layers.These soils here more calcium carbonate and less organic matter.These soils are divided into three main categories.
BONGAR SOIL;
These soils are found in the historic indus plain and are the best soils for agriculture in the
country.Usually they're far from the present day bed of the indus river.
Bongar soils cover a vast area of indus plain.The area includes most of the part of punjab, peshawar,mardan, bannu, and kachhi plain.A major part of the provinces of sindh is also comprised of these soils.Some of these soils are rich and irrigated give very good production...
KHADDAR SOIL;
This soil found along pakistan's rivers.It formed when every year during flood a new layer of totally clay was deposited.These soils have low content of organic matter and it...
INDUS DELTA SOILS;
These soils cover the river indus delta.Most of these soils are very clayey and were developed under seasonal floodwater.They extend from hyderabad to the south coastal areas.Rice is cultivated as in the major part of these soils.
MOUNTAIN SOILS;
These soils mostly cover the highlands of northern and westernareas of pakistan.The soil of northern mountainous area have high content of organic matters becuase the climate is moist.The soil of western mountainous areas is arid and semi arid.The soil of potwar plateau have high lime content.They are productive when plenty of water is available.
SANDY DESERT SOILS;
These soils are made by the deposition of sand layer by layer after year for thoushands of years.They're found in the arid abd semi arid areas of pakistan.......
lumbering
LUMBERING IN THE FOREST ON THE PACIFIC COAST OF NORTH AMERICA;
Depsite the long active exploitation of the forest on the pacific coast lumbbering is still the outstanding industry of northwestern United States and western canada.The pacific forest contain some on the finest and most useful timbers in the world and are now the leading source of supply for the united states and canada.North of san francisco they cover tremendous area on the slopes of the coast ranges sierra nevda's and cascades and extend as far north has central alaska.A significant advantages of these forest lies in their manner of occurence in thick growing almost pure stands.Valuable species are coniferous softwoods,including the majeistic. Douglas fir which reaches a diameter of 6 feet or more and a height of more than 260 feet.Its strong durable word of medium weight it to all kinds of constructions.
Methods of logging depend to considerable extent upon the chracter of the timber and climate and physiographic conditions.Logs are skidded to main roadways or railways lines.Nearbly all mills have access to road and rail as well as water transportation.Becuase of the indented coastlined much valuable timber is within a distance of few km of coastal mills...
LUMBERING IN THE ROCKY MOUNTAINS;
In the region of rocky mountains in canada the united states and their southern extensions in mexico there are forest of considerable importance.Lumbermen in these forest use all the logging methods employed in the pacific area and in addition various transportation from seemingly inaccessible places.An active market is furnished by the farming population of adjacent plains and plateaus.
LUMBERING IN THE TEMPERATURE FORESTS OF EURASIA;SOFT WOOD FOREST:
Except for coastal marshes and highh moorlands most of europe north of the mediterranean sloped is naturally a forest region.But much of the original forest was cut long ago.As they grow faster than hardwoods, coniferous forest have received much attention.Germany,france, belgium, and denmark are leaders in caring for their forests.Forests in many of these countries are so carefully supervised to prevent excessive cutting that most sawmills are small compared with those in pacific coast forests.These mills reduce wood as much as possible though these forests yield abundant materials under proper utilization import forest products from adjacent areas especially northern europe.
TROPICAL HARD WOODS EQUATORIAL EVERGREEN AND MONSOON FORESTS;
These forests are generally found in the tropical monsoon and equatorial regions of the world.They are ever green bread leaved trees grown in the areas where there is no dry season and heavy rainfalls throught out the year.Due to extremes heat and moisture the growth is dense and luxuriant.Where rainfall is less deciduous forests teak and sail type trees are found some if them are highly valuable......
forest resources
FOREST RESOURCES;
Natural vegetation has been central in human.Becuase it,provides ecosystem services for climate range and forage wildlife habitat,biotic diversity, waershed protection, soil erosion control etc.
The need for greater food production has led to a massive increase in cropland.By early 2010's almost 40 percent of earth's land surface had been converted to croplands and permenant pastures.This conversion has occured largely at the expense of natural vegetation.
NATURAL VEGTATION OF PAKKISTAN;
In pakistan the following vegetation types are reconized.
1. Grassland
2. Desert vegetation
3.Forests.
Of the four forests cover percentage group >70%, 40-69%, 10-39%, 0-9% pakistan lies in the last category;0-9%. Between 1981 and 1990 there had been a 4.3% decrease in forest areas of the tropical asia and oceania which pakistan is a part of.During the same period 0.6% deforestation had been occuring each year. This is an alarming situation and needs to be stopped and then reserved, if possible.
Total forest area under the control of the forest departments including azad kashmir and the northern area is 4.26 million hectares.The per capita forest area is only 0.037 ha compered to the world average of ONE ha.Main reason for this is that more than 70% land area of pakistan is arid and semi-arid with annual rainfall of 250-500 mm; too low and erratic to sustain natural vegetation and to plan afforestation/regeneration progammes.
OF 4.26 million hectares of forest area only 1.12 million hectares 26.3% produce timber and firewood the rest are meant to protect the watershed and erodible lands.
Besides forests the forest departments also control 6.4 million hectaresof rangelands.In fact there are about 51.3million hectares of rangelands in pakistan.These ranges provide sustenance to livesstock population of about 98.6 millions.Being under incessant grazing pressure these land are producing harldy 10-15% of their actual pote,ial iver grazing has intensified the problems of desertification resulting in accelerated soil erosion and degradation of plant communities.
Present the forest area by type and rangelands in pakistan including azad kashmir and the northern areas.......
