Transport in Saudi Arabia
With the arrival of petrodollars, the Kingdom of Saudi Arabia has initiated many mega infrastructure development projects in the country, and the extensive development of the transportation network has followed suit in support of various economic developments. As a result, the country now boasts an extensive transportation network.
Total: 221,372 km (137,554 mi)
Paved: 47,529 km (29,533 mi) (includes 3,891 km (2,418 mi) of expressways)
Unpaved: 173,843 km (108,021 mi) (as of 2006)
Roads in Saudi Arabia vary from eight-laned roads to small two-lane roads in rural areas. The city highways and other major highways are well maintained, especially the roads in the capital Riyadh. The roads have been constructed to resist the consistently high temperatures and do not reflect the strong sunshine. The other city highways such as the one linking coast to coast are not as great as the inner-city highways but the government is now working on rebuilding those roads. In October 2013, a group of auto enthusiasts drove some 2,000 km (1,200 mi) through Saudi Arabia in search of the best driving road, and named the Jeddah-Taif-Al-Hada highway as "motoring nirvana".
Saudi Arabia encourages road transport as it has maintained one of the lowest petrol prices in the world, at $0.13 per liter ($0.48 per gallon) .

As a result of over-reliance on road and air travel, the rail transport has not received a similar level of investment in Saudi Arabia. However, there are now plans for expansion within the kingdom's railway infrastructure. Some of these plans are:
- The Saudi Landbridge Project is a project that aims to link the port cities of Jeddah, Dammam, and Jubail. It will also pass through Riyadh and serve its dry port. The line linking Riyahd and Jeddah is planned to be c. 950 km (590 mi) long, whilst the line connecting the two cities of Dammam and Jubail should be c. 150 km (93 mi). 
- The Haramain High Speed Rail Project (HHR) underway in the Western province, connecting Makkah with Jeddah and Madinah city with a 453 km (281 mi) long railway line. This electric passenger double line will be created to transport the large number of Hajj pilgrims, which the SRO considers transportation for, an urgent matter. 
- The Al Mashaaer Al Mugaddassah Metro Southern Line is part of the Makkah Metro rail transit system, which was developed in Makkah city. This is a 18.1 kilometers (11.2 miles) track developed as exclusive shuttle a predicted 8 million pilgrims between Mecca, Mount Arafat, Muzdalifa and Mina on the annual Hajj pilgrimage.
