Madrid's motorway hub network.

Madrid is the most important hub of Spain's motorway network and is surrounded by

fourorbital motorways: M30, M40,M45 and M50. M30 circles the central districts and

is the inner ring motorway of Madrid. Significant portions ofM30 runs underground

and its urban motorway tunnels have sections of more than 6 km (3.73 mi) in length and

3 to 6 lanes in each direction, between the south entry of the Avenida de Portugal tunnel

and the north exit of the M-30 south by-pass there are close to 10 km (6.21 mi) of

continuous tunnels. M40 is a ring motorway which borders Madrid at a mean distance

of 10.07 kilometres (6.26 mi) and it has a total length of 63.3 km (39.33 mi). M45 is a

partial ring around the city serving the metropolitan area of Madrid. It was built to help

alleviate the congestion of the M40 from the southern to the north-eastern, runs between

the M40 and the M50 where the two ring motorways are more separated. M50 is the

outer of the Madrid orbital motorways and has a total length of 85 km (52.82 mi). It

services mainly the metropolitan area at a mean distance of 13.5 km (8.39 mi).

advantage to these roads is that they allow true fast travel from the first kilometer.
