I want to know the answer to the following question:
How long is Portugal's total road network?
All the background I'm provided with is that "Opened in 1944, the first motorway (which linked Lisbon to the National Stadium) was an innovative project that made Portugal among one of the first countries in the world to establish a motorway (this roadway eventually became the Lisbon-Cascais highway, or A5).". Is that enough to answer the question?
Answer: no
