The line 3 (Legazpi-Arguelles) will be closed since June 11th until end September. Metro will carry out work on the 2nd phase of modernisation, maintenance and improvements. These include:

* Modifications to all stations. New entrance halls will be built and elevators will be installed to improve accessibility.
* Enlarged platforms. New trains will be incorporated that will increase passenger capacity.

There will be a special bus line (E3) at no cost for the passenger in order to minimise the disturbances caused. The line will follow more or less the route of the metro line.

Stations impacted are Legazpi, Delicias, Palos de la Frontera, Embajadores, Lavapies, Sol, Callao, Plaza de España, Ventura Rodriguez, Arguelles, and Moncloa.

Thank you for the heads up on this info. I won't be angrily surprised when I go to use line 3 this summer and it's not operating. This happened last summer too!
At least we can take the bus.

I'll keep that in mind too as I'm sure it'll come in handy upon my arrival in MADRID this weekend! (woo hoo!!!)

For those numerically challenged , line three is the YELLOW LINE which crosses through SOL from southeast Madrid to northwest Madrid (more or less).

Saludos, MadridMan

It will probably happen again next Summer. The works are really huge, that is why they decided to close the line in Summer, the season when the demand is lower. All stations will be enlarged from 60 meters to 90, adapted for impaired people, and the line itself will be enlarged 8,7 kilometers to the South, opening 7 new stations. The completion of the works is expected by Spring 2007.
