The Autostrada A24, or Strada dei Parchi is an autostrada 166 kilometres (103 mi) long in Italy located in the regions of Lazio and Abruzzo connecting Rome to Teramo, near the Adriatic Sea. Starting from the Grande Raccordo Anulare, the A24 runs broadly north-east across the Abruzzese Apennine Mountains. Between L'Aquila and Teramo it passes through the 10 kilometres (6.2 mi) Gran Sasso Tunnel. The private company Strada dei Parchi S.p.A. currently manages the motorway. The name "Parks Motorway" comes from the fact that the Maiella National Park, the Abruzzo, Lazio and Molise National Park and the Gran Sasso e Monti della Laga National Park can be reached from this motorway. It is a part of the E80 European route.
