Memories of going from Santander to Barcelona and my entire family arguing over which lane to take. Enjoyed ice cream in Bilbao before going back to the shouting match. The AP-68 was nice though.
Wow, that motorway is amazing! Reminds me of most layouts you'd see in most American cities. Also, why (and how) some signs are desperate to get traffic away from A-8 thru Bilbao?
+WolfGuy100 The destinations for through traffic (San Sebastián, Vitoria) are first signed via AP-8 (a toll road south of the city) and then via N-637 (the northern bypass). AP-8 was built to relieve the A-8 through the city but doesn't attract much traffic due to the tolls.
