Thanks for the review
I/2 - PodBar - is this not II/333? (It's definitely a weird end - downgraded for D0 prematurely)
I/2 ends there because there's the Prague city limit. II/333 is not signed.
I/3 - fine (assuming D3 hasn't extended south one junction)
I've changed D3 wp to D3(104) to avoid trouble when the next D3 section will be opened this fall.
I've also checked other routes for situations like this.
I/8Bre - does this extend further into Praha?
No, it isn't. I've checked it when I've added the eursf routes.
I/34 - I20_W -> I20_E (also check E road routes between this point and I/3)
Yes, E49 is signed via I34 now, not I20/I3.
I/35 - Kos -> 22 (also on E442). I14 -> 23, CesMla -> 24
What's your source? I couldn't find numbers on GSV. Only OSM indicates them but OSM also indicates 25 for 26, 29 for 31, 31 for 33 et cetera. Our wp labels are correct according to GSV though.
