Longest 2*4+ lane highway route in your country

After the great success of the 2*3 thread, here a new one! let's make it a little bit more exclusive...

I want to see which one is the longest 2*4 route in your country: only highways with BOTH direction with 4 or more lanes are accepted. Emergency lane is also a requirement.

We are talking mainly about interurban highways, I assume in the US there will be several long stretches inside the city itself

In Italy - to start - we have today only 3 real 2*4 highways, all fairly short:

MILANO-BERGAMO (37 km) the longest currently
MILANO-LAINATE (a short stretch)



Construction shall start soon for a new 4-lane section on A4 between the highways to Malpensa and Milan, while the hurban stretch of the A4 will be made into 4 lanes without emergency lane (dynamic 4 lanes). Most bridges have been already updated to 4-lane wide highway after the HSR construction

MODENA-BOLOGNA (33 km)



In red the plans to make the A1 into a 4-lane highway for most of its course (esxcept river Po crossing). Also here the bridges have been all upgraded to 4-lanes highway thanks to the construction (near the highway) of the HSR line.

The Netherlands:

By 2011 it will be the A2 motorway from Interchange Amstel near Amsterdam to Interchange Deil, a distance of 60 kilometers.

Amstel - Holendrecht: 8 lanes
Holendrecht - Oudenrijn: 10 lanes (end 2010)
Oudenrijn - Everdingen: 8 lanes (2011)
Everdingen - Deil: 8 lanes (end 2010)

I think the stretch between Casalpusterlengo and Piacenza is not scheduled because it is the most difficult (and expensive), but they clearly want to enlarge all A1 between Bologna and Milano; probably after the 2 stretches between Modena and Piacenza and between Milano and Casalpusterlengo will be completed they will start even the last branch

Interstate 5 in California is at least 2x4 from its beginning at the Mexican border to the CA 91 interchange at mile 114, and from I-605 at mile 124 to CA 99 at mile 221.

None, it's still under construction. The Amsterdam - Utrecht section is currently being widened from 6 to 10 lanes, and the Everdingen - Deil section is currently being widened from 4 to 8 lanes. Both projects should reach full capacity in about 6 - 8 months. The Utrecht - Everdingen section will start construction in about 6 months, with a completion one year later.

that cannot be ruled out, however the above constructions are into the national contract with "Autostrade per L'Italia" (the contract with which the government "extends" the payage system in Italy in exchange with new works and renovations"). So they are bound to be implemented in a foreseeable future

Anyway it will be more than 120 km 4*4, it's already pretty good

Only one year? clearly the Netherlands have different standards from Italy In our case 2-3 years at least

In Spain if I'm not wrong it is the A-6 from Las Rozas to Guadarrama. Only 35 km.

Will the left lane be closed most of the time and function as a shoulder except during rush hours, like on the A4?

This highway between Beijing and Tianjin is 135 km long, not sure whether longer one exists in China.



The guy in the video above drives at 270 km/h on the highway.

No, it will be a fulltime functional 2x5.

Is there really a need for a 4-lane highway between Lodi and Casalpusterlengo? Whenever I took the highway to Milan, it started to get crowded after Lodi, at Casalpusterlengo the highway was almost empty in comparison.
