The Guidelines define the TEN-T roads as composed of motorways and high-quality roads – existing, new or to be adapted. The total length of the current TEN-T roads, including ordinary roads yet to be upgraded, was approximately 98.500 km in EU27 in 2005.
The total length of the current TEN-T roads composed of motorways and high-quality roads was approximately 70.200 km in EU27 in 2005.
In 2005, about 70% of the existing TEN-T road consisted of motorways and high-quality roads. The remaining roads are still to be constructed or upgraded to the general target of the Guidelines. According to some estimation, the length of the TEN-T roads composed of motorways and high quality roads will be about 85.000 km in 2013 and about 90.500 km in the horizon 2020.
Significant developments for the network are improvements in road conditions (capacity, additional lanes, electronic toll collection, emergency and incident management, traveller information service, etc.). However, these kinds of developments improve safety, comfort and the general level of services but they do not increase the length of the TEN-T roads or change the category of the link type (motorway, high-quality road) of the section.
