Doha has recently been undergoing a huge expansion to its transportation network, including the addition of new highways, the construction of a new airport, and the planned construction of a metro system. This has all been as a result of Doha's massive growth in a short space of time, which has resulted in congestion on its roads.

Roads:
Doha has a comprehensive road network made up primarily of two and three lane dual-carriageways. As a result of Doha being a relatively young city, Doha's roads are wide and usually include service roads and large central dividers. While traditionally roundabouts have been used as intersections in the city, this has recently changed as a result of the huge load on the city's road networks. Many major roundabouts have been removed and instead either replaced with traffic lights or with underpasses and overpasses. Furthermore, many major thoroughfares in the city are being converted into highways in order to accommodate the huge increase of traffic on the city's roads.

Highways:
There are five main highways connecting Doha to its neighboring cities. These are the Dukhan highway to the west of the city, the Al-Shamal Road, connecting Doha to the north of the country, the Al-Khor Expressway, connecting Doha to the northern town of Al-Khor, and the Wakrah/Messaid Road, connecting Doha to the south of the country. Finally, Salwa Road runs through south Doha and connects the city to the Saudi border to the south of the country.
These highways are all currently undergoing expansion, and are being expanded within Doha itself.

Doha Expressway (D-Ring Road/Al Shamal Road):
The Al Shamal-Road has traditionally connected to the D-Ring Road in Doha, a three-lane dual carriageway that connects the city on a north-south axis. However, as a result of congestion, the D-Ring Road is being converted into a major highway through the city, and its name has been changed to the Doha Expressway, connecting Doha as a whole and connecting Doha with the north of Qatar. Several phases of the Expressway have been completed, including the Al Shamal Bridge, the Landmark Interchange, the Gharaffa Interchange, and the Midmac/Salwa Road Interchange.
The Al Shamal Road is also undergoing significant expansion as part of the Doha Expressway project. The Road is being expanded into a four-lane highway (a total of eight lanes) with major interchanges which will better serve the country than the existing two-lane dual carriageway. Furthermore, the new Doha Expressway will connect Doha with the planned Qatar-Bahrain Friendship Bridge at al-Zubarah, connecting the two Gulf states in a similar manner Bahrain and Saudi Arabia are currently connected.

Lusail Expressway:
The Lusail expressway is expected to connect the new city of Lusail, currently being constructed north of Doha, to central Doha, along with connecting the Pearl to the mainland. The expressway is expected to take the path along the former Istiqlal Road, now Lusail St., and will be a 4-lane dual carriageway passing through the city. The expressway will extend from Lusail City, through Rainbow roundabout, Qatar Sports Club roundabout, and the fire department roundabout.

Dukhan Highway:
The existing Dukhan highway has been undergoing a reconstruction project for several years, with new interchanges having been constructed and the road being significantly expanded. In the future, it is planned to expand the highway so that it connects directly into Doha through a system of underpasses and overpasses, with plans to replace the Tilted Roundabout, the Markhiya Roundabout, and the TV Roundabout, all major roundabouts in Doha, with underpasses and overpasses.

Salwa Highway:
The Salwa Highway project's first phase has been completed. This phase involved the expansion of the highway, which connects Doha to the southwestern town of Salwa on the Saudi Arabian border, into a four-lane highway with grade separated interchanges. The rest of Salwa Road is expected to be expanded and upgraded, from the recently completed Industrial Interchange to the Jaidah flyover, including the construction of an underpass at the Ramada signals, Doha's busiest traffic light intersection. This project is not expected to commence until after the completion of the Doha Expressway.

F-Ring Road:
The F-Ring Road will be the sixth ring road in Doha, and is being constructed as part of the transportation network leading to the New Doha International Airport. The new highway will connect the airport to the Corniche at the new Ras Abu Aboud interchange, currently under construction, and will involve a new ring road south of the E-Ring Road.

Bus System:
An extensive bus system, operated by the government-owned Mowasalat company, currently operates in the city of Doha. The bus system covers many areas of the city, and there are stops throughout the city. The bus system is mainly used by lower-income groups, and does not attract many from the higher-income groups in the city, which has resulted in increased congestion on the roads of Doha, as most people prefer cars.
The main bus station is located in the Souqs area of downtown Doha, and services operate to all major towns in Qatar.

Taxis:
The Mowasalat company operates all taxis in Qatar under its Karwa brand, with over a thousand taxis operating in the capital. There are many taxi stands in the city, and while in the past difficulties arose in finding taxis due to the small number of taxis on the roads following the launch of the company, today this has become less of an issue.
Fares start at QR4.00, and the majority of taxis are well-equipped, comfortable sedans including cars such as the Toyota Camry and the Ford Mondeo.
Airport taxis, found at the Doha International Airport, are also available, in the form of the Ford Freestar. Taxis from the airport start their meters at QR18.00.
Numerous unlicensed taxis operate in Doha. Exact numbers are hard to quantify but it is believed that unlicensed cabs far outnumber Karwa cabs.

Port:
The Doha Port is among the country's largest ports, and is located just off the Doha Corniche. The port is the main seaport servicing Doha, although plans for a new port are underway due to the port's location in central Doha and the resultant traffic and pollution problems, the proposed location of the port is near the town of Al Wakra, just south of the New Doha airport.
