Classification of Roads

Total lenght of roads and streets – 73 592 km. Average road network density – 1.139 km per 1 km2.

Total lenght of roads under the supervision of SJSC “Latvian State Roads” – 20 131 km. Average state road network density – 0.312 km per 1 km2.

Main Roads
According to the law „On Roads”, main roads are the roads that connect the state road network with the main road network of another country; and the capital city – with other cities in the country or city bypasses.

Regional Roads
According to the law „On Roads”, regional roads are the roads that link region administrative centers together or connect with state cities, or the capital city, or main or regional roads, or state cities together.

Local Roads

According to the law „On Roads”, local roads are roads that connect region administrative centers with region towns, populated areas that have a rural municipality administration, villages or other state roads or link separate region administrative centers together.

The State Joint Stock Company “Latvian State Roads” manages 971 bridges, out of which 907 are bridges of reinforced concrete, 14 – of stone, 43 – of metal, and 7 – of wood. The total length of bridges is 31 173 meters.

Black Spots

The Map of Black Spots in Latvia

The State Joint Stock Company “Latvian State Roads” (LSR) has developed a new black spot map of the state roads. In comparison with the previous years, the number of black spots has decreased. In the time period from 2011 until 2013, 58 black spots were recognized on the state roads.

 In the time period of 2009 – 2011, there were 62 black spots on the state roads, in 2007 – 2009, there were 174. The black spots are the most dangerous places on the state roads.

The black spot is defined as a road location where in the length of one kilometer at least 8 road traffic accidents have happened or at least 3 persons have died in the time period of three years. An intersection can be considered as a black spot if accidents have happened in the radius of 150 meters in each direction.

One of the reasons for the decrease of the black spots is safety improvement measures performed by LSR. For example, a roundabout has taken the place of a dangerous intersection on Riga bypass Salaspils – Babīte (A5). Traffic lights are installed on Bauska road by the turn to Baloži. Quite substantial funding was invested in improvement of Koknese infrastructure – lighting was installed, pedestrian roads were constructed, a street parallel to the Daugavpils road was built, as well as, signal-controlled intersection was constructed. Due to these traffic safety measures, there is no black spot in Koknese anymore.

At present, priority is the black spot on Ventspils road, intersection with the road Jelgava – Tukums. Next year it will be reconstructed as a roundabout. Also pedestrian roads in Līgatne and Ulbroka will be constructed, and lighting will be installed on Tallinn road, near the Baltezers arboretum.

Traffic Intensity

Interactive map

In 2014, traffic intensity was the highest in the state road sections near the capital city, i.e., in Riga region. On average, 37 000 vehicles per day (AADT – annual average daily traffic) were travelling on the road A10 Riga – Ventspils, section Riga border – Jūrmala; 34 300 vehicles per day were taking the road A2, section Riga border – A1 (A2 km 14.1).

Almost 20 000 vehicles per day were travelling on the road A6, section Riga – Ogre, also the road A7, section Riga border – turn to Ādaži (km 5.6), the road A2, section A1 – Inčukalns, the road A8, section Riga border – turn to Ozolnieki (P100).

In 2014, traffic intensity from 9000 to 14 000 vehicles per day was established on the road A1, section Ādaži intersection – Saulkrasti bypass, the road A2, section Inčukalns – Līgatne, the road A3, section P11 – Valmiera overpass, the road A7, section Ķekava – Iecava, the road A9, section P106 – Liepāja, and the road A10, Jūrmala bypass.

Comparatively lower traffic intensity within Riga region was on the road A3, section Inčukalns – Ragana (7300 AADT), on the road A1, Saulkrasti bypass (7000 AADT), on the road A9, section A5 – turn to Kalnciems (5700 AADT).

In 2014, relatively high traffic intensity was on Riga bypasses, roads A4 and A5 (770017 600 AADT).

The highest intensity of heavy traffic (22005000 AADT) was on the road A6, section Riga border – turn to A4 Riga bypass, on the road A10, section Riga border – Jūrmala, on the entire road A7, on the road A8, section Riga – Olaine, on the road A2, section Riga border – Garkalne.

Naturally, high intensity of heavy traffic (14003500 AADT) is on Riga bypasses, roads A4 and A5. It constitutes approximately 21 – 29 % of the total traffic intensity on these roads.

Relatively high intensity of heavy traffic was also on the following roads:

  • Road A2, section Garkalne – turn to Cēsis, 1900 AADT,
  • Road A3, Valmiera bypass, 1870 AADT,
  • Road A8, section Olaine – Ozolnieki, 1700 AADT,
  • Road A1, section Riga border – Salacgrīva, 1700 AADT,
  • Road A6, section A4 Riga bypass – Ogre, 1700 AADT,
  • Road A9, section Grobiņa – Liepāja, 1680 AADT,
  • Road A6, section Aizkraukle intersection – Jēkabpils, 1600 AADT,
  • Road A3, section Inčukalns – Ragana, 1460 AADT,
  • Road A10, Jūrmala bypass, 1330 AADT.

The biggest proportion of heavy traffic is on the road A15, Rezekne bypass (48 %), A12 (35 %), and A14 (38 %).

Weight restrictions

Seasonal weight restrictions

Weight restrictions on bridges

In autumn and spring, when the soil foundation thaws and dampens, bearing capacity of the road pavement is reduced. It affects gravel roads the most. To prevent disintegration of these roads, temporary restrictions for heavy traffic are implemented on many local and some regional roads. This practice is universally recognized, and it is implemented in other countries with similar weather conditions.

These traffic restrictions do not apply to the state main roads and the most important regional roads. Therefore, freight transit traffic and the most of the domestic transportation of goods are not affected. Restrictions are implemented every year in all state regions. Prohibitory traffic signs that define maximal full mass (usually 10 tons) affect approximately 10 000 km of roads with gravel pavements and worn-out bituminous pavements. Municipalities act similarly regarding roads under their management.

Restrictions are implemented and cancelled in accordance with actual condition of every road and evaluation of possible damages. On some roads these traffic restrictions are permanent.

We kindly ask the operators of road transport to take into consideration these temporary restrictions and comply with them. Road improvement can be only performed when the structure is dry.

Permits for heavy traffic are not issued during thaw. Situation is controlled by regional employees of the SJSC “Latvian State Roads” in cooperation with the State Police.

Restrictions do not apply to the operational vehicles and “raw milk vehicles”, registered in the Road Traffic Safety Directorate, that can travel on previously approved routes.
