The total length of national roads as at 1 January 2009 was 16,487 kilometres, i.e. 28.4% of the total length of the Estonian road network, which is 58,034 kilometres.  The length of E-roads in Estonia is 935 km.

Due to taking over certain local roads into the national network, reconstruction of traffic junctions and some corrections in road register the total length of the national roads increased by 21.8 kilometres.

Of the national roads, 1,602 km (9.7%) are main roads, 2,391 km (14.5%) basic roads, 12,444 km (75.5%) secondary roads and 50 km (0.3%) ramps and connecting roads included in junctions.
The length of paved roads increased by 243 km from last year and is currently 9,922 km, i.e. 60.2% of the total length of the national roads. The majority of this increase happened on account of paving gravel roads.

The density of national roads is 380 km per 1,000 km2 and the density of the entire registered road network is 1,336 km per 1,000 km2 of the territory.

There are 926 bridges on national roads with the total length of 21,342 m, including 6 wooden bridges with the total length of 214 m.

The national road register, providing information on both the national roads and other public roads is publicly available to everyone.

As at January 1, 2008 the basic data on both the national and local roads has been entered in the new web-based road register. In cooperation with the Land Board, a new national roads layer based on the basic map of Estonia has been introduced for the purpose of updating the data and adding new data.

Upon studying the diagrams of changes in evenness, improvement can be observed on all road types, but still mainly on the main roads. The average IRI value of the entire national roads network has improved as a result of permanent and summarily growing volumes of the construction, repair and maintenance of pavements. The main measure to achieve the improvement of the average evenness of basic roads and secondary roads is continuously surface dressing.
