I have just seen an advert in our local English newspaper for property in Catalunya, it stated that there was an airport "under construction" in Tortosa.

Anyone else heard about this ?

There maybe some confusion but the same ad' mentioned Reus, Barcelona & Valencia along with Tortosa.

Just found this,not near Tortosa but near enough Plenty of numbers and measurements for the brainiacs

Castellon Costa Azahar Airport, located in the area of Vilanova d'Alcolea, will have a 2,700 metres runway that can be extended to 4,000 metres and the installations will include 60,000 metres of parking, and a 9,000 square metres terminal to handle 2 million passengers a year.

The new airport will be connected to the A-7 motorway through a fast lane leading to the most important tourism centres in the north of Castellon province.

A motorway will connect Castellon city with the Airport, and the Cabanes-Oropesa highway will enable access to the "Dream World" future theme park.
