I've were are not talking about highways, Belgium has many straight National roads. Nearly all national roads before the highway network where build in perfect straight lines between towns and cities.


The Netherlands has a 23km strech highway perfectly straight on A7 across Afsluitdijk.

[clarification needed] You said "not highways", which are secondary roads, but then you mention "national roads", which are highways by definition. "Motorway" and "highway" aren't synonymous.

A7 has four dents at the rest area in the middle of the dam.

I'll wrote which motorways were opened in that time, so you can check. More strethes where interrupted by modern interchanges.


A3 Neaples-Pompei
A4 Turin-Brescia and Padua-Mestre (Venice)
A7 between Genua and Serravalle Scrivia (Southbound carriageway) no have long straights because of mountains
A8
A8/A26 between A8 IC and Sesto Calende exit
A9 between A8 IC and Como
A11 Firenze-North of Pisa (sea) (have 2 stretches changed in postwar)


There is also RA13, buildt by AMGOT near Trieste in 1945-47
Also SP8 Rome - Ostia was considered a motorway when it opened in 1927.
A10 Genoa - Savona was also designed before the war, although it was actually built between 1954 and 1956 (1st c/w, the 2nd was added 20 years later).

Long sections of route E67 in Poland (Warszawa - Białystok) used to be perfectly straight. Now this road is being upgraded to motorway standard and isn't that straight anymore.

http://www.openstreetmap.org/directi...2.6647/21.7049
http://www.openstreetmap.org/directi...2.8948/22.0660
http://www.openstreetmap.org/directi...3.0193/22.3723
http://www.openstreetmap.org/directi...3.1277/22.6982

The parallel railway line (to the south) is also very straight.

Actually, a lot of roads in the east of Poland (that used to be a part of the Russian empire) have long straight sections.

I found another contender for Spain:

A-68, 15 km: https://www.google.es/maps/dir/41.91...a=!4m2!4m1!3e0

This stretch was built as a dualling of the former N-232, which explains the exceptionally long straight --otherwise the maximum straight lenght for new motorways is 2 km.


According to several sources I've found, the longest straight road (non-motorway) in Spain is this 23-km long straight of the N-301 between El Provencio and Minaya, which also features two cloverleaf interchanges (N-310 and A-43):
https://www.google.es/maps/dir/39.27...a=!4m2!4m1!3e0

Another long straights (>15 km) I've found in the national road network:

18.8 km N-322: https://www.google.es/maps/dir/38.88....0395718,12.5z

17.4 km N-110: https://www.google.es/maps/dir/40.58...a=!4m2!4m1!3e0

16.1 km N-234: https://www.google.es/maps/dir/40.78....342747,12.21z

I already mentioned the first two:

I've only measured 16.7 km on N-110, your route doubles back at the end as Google Maps considers N-110 as being divided at the N-502 intersection (it is not). I've actually been to the N-234 one, I thought it was in Soria province (it's almost a straight shot between Almenar and Soria) but it is in Teruel where the road has been replaced by the not-so straight A-23 (The scenery is boring between Teruel and Calamocha anyway).

Finnish motorway, 5.0 km (3/E12 in Nurmijärvi):

https://www.google.fi/maps/dir/60.50...a=!4m2!4m1!3e0

Unfortunately the length given by Google is not accurate enough to tell, whether this is actually more than 5 km (as required) or not.

There must be thousands of straight segments of that length in the U.S. and Canada. Thanks to the way roads in the Midwest (and Canadian Prairies) were laid out along survey lines.

If you look closer, you will see that most of the time the roads are only very straight, but not perfectly straight. The Interstates vary along these lines quite a bit.

Lets also not forget that only lines of longitude are perfectly straight, there is only one straight line of latitude, and thats the equator!

Originally 24 km when it was opened, btw, with time was reduced by declassification of begins & ends due to expansion of urban areas and new ICs

Norway? 7.1 kms on rv 2 at Haslemoen. Regular highway, though, don't know about motorways, but probably E6 at Kløfta.

Nowadays in Spain we will not find these straight on roads or motorways. Only current ones or upgrading them...

New ones cannot have a straight longer than 2 km to avoid accidents (boring when driving, they must put small curves that you could drive on 120 but be aware on motorway)


Anyway... not motorway nor road... longest straight infrastructure in Spain is High Speed lane in Aragon between Zaragoza and Barcelona. About 40 km or so
