2022 Interstate Highway Renumbering

The 2022 Interstate Highway Renumbering is an upcoming reorganization of the Interstate Highway System in Europe. The new system, based on the Interstate's location, will replace some highways with new numbers implemented from 2012 or 2021. It was first signed in October 2021 and is expected to go into effect somewhere in 2022.

Interstate 3 and Interstate 103 (Portugal)
In northern Portugal, PDOT originally intened to renumber I-26S and I-26 in Portugal to I-3. After the section between former I-501 and I-26 in northwestern Spain was opened, the section in Portugal was signed as Temporary I-3 and Temporary I-103, beacuse it was intended to be designed with these numbers in the future.

Interstate 7 Extension
I-7 was intended to be extended west towards northwestern Spain, specifically near León at I-26.

The plans for extending the Interstate Highway was scrapped on December 17, 2021.

Interstate 22 Relocation
The current I-22 runs through Slovenia and southwestern Hungary, connecting Ljubljana, Maribor, and Budapest via I-81. Soon, it will be replaced by I-42. The new I-22 will replace the entirety of I-16 between Plovdiv and Burgas in Bulgaria. As of December 20, 2021, EUDOT accepted this number as they will renumber some interstates to make way for the new number.

Interstate 30 Extension
I-30 is planned to extend from its eastern terminus with I-20 into France, and then trace trough the cities of Bayonne and Toulouse. The extension will remove a section of I-25 which runs from I-20 in Bayonne to I-15 in Toulouse, and then runs concurrent with I-15 to the north until leaving the city.

Interstate 42 Relocation
The current I-42 runs between the French cities of Rennes and Le Mans. As of December 20, 2021, the new alignment will be the same alignment as I-22 in Slovenia and southwestern Hungary. It will connect the capital cities of Ljubljana and Budapest (via I-81). It will also connect the cities of Maribor and Graz (Austria) via I-79.

Interstate 62
Interstate 62 will run as the same alignment as where I-42 connects Rennes and Paris (via I-40) in northwestern France. Plans for I-62 started on December 20, 2021.

January 2022
On January 9, 2022, the CEO of EUDOT has stated the future Interstate Highways to the east "will receive their new signage of Interstate Highways first before the west does due to our complicated planning of Interstate Highways in northwestern Iberia." The inclusion of Interstate Highways in northwestern Spain and northern Portugal struggles to propose new Interstates. As of January 5, 2022, PDOT and SDOT has proposed several numbers for a new primary, auxiliary, and suffixed Interstate Highways, mostly around the northwestern-most portions of the Iberian Peninsula.

Interstates 1E and 1W
Interstate 1W and Interstate 1E were two suffixed Interstate Highways that was proposed to split Interstate 1 from Porto. I-1W was to start in Porto to I-1's northern terminus in A Coruña, and I-1E to connect Porto and Lisbon with Gijón.

On January 9, 2022, the CEO of EUDOT has chosen the suffixed Interstate Highways and kept the proposal of I-801 around Porto, and removed the proposal of I-701. A few days later on January 12, the suffixed proposal was removed and instead, created a plan to realign I-26 to connect Porto, Portugal with Burgos, Spain. As of that day, the proposal of I-801 still exists.

Interstate 7 Relocation
For the third time, I-7 has been touched again. This time, SDOT has planned to relocate the Interstate Highway to connect León at I-26 with Gijón at I-30.

Interstate 9 Relocation
I-9 has yet been relocated again for a third time. The first time I-9 was relocated, it was slated to replace a section of I-7 between Madrid and Burgos, and for the second time, connect Murcia with Madrid and end at I-214. As of January 12, 2022, it is now planned to run its first-planned alignment, connect Madrid at I-14 with Burgos with I-20.

Interstate 13 Relocation
The relocation of I-13 was intended to not just replace the entirety of I-9, but also replace I-18. This plan was scraped as of December 2021, until it was revived as of January 12, 2022, but this time, it will replace the entirety of I-9 between Valencia and Zaragoza.

Interstate 26 Realignment
...

The current plans for I-26 as of January 12, 2022, is to serve as a direct connection between Porto and Bilbao via I-20 and I-18.

Interstate 28 (Spain)
There is currently an I-28 connecting Lyon, France via I-20 and three Swiss cities: Geneva, Bern, and Zürich.

As of January 11, 2022, there are plans to redesignate a portion of I-26 between Vigo and I-26 north of the Portuguese border in Spain to Interstate 28. This section will be seperate from the current I-28. The plans for I-28 was accepted as of January 12, 2022.

Interstate 50 Extension
January 30, 2022...

I-50 will have the same situation as I-59 in Austria; it will be signed as an interstate highway, but have a different color, which has yet to be announced.

Business Routes
On November 18, 2021, the CEO of the European Department of Transportation (EuroDOT) announced the new business routes for the Interstate Highway System. There will two types of business route: The loop, and the spur.

EuroDOT has added several business routes for the future, and the CEO made an explanation that "the other business routes in bigger countries, will be designated after we add the business routes in the smaller countries, but that depends on how many business routes we have designed."

Countries with the * may not be designed immediately with the new business routes. The following countries will receive business routes along the renumbering are:
 * Austria - 1 loop (I-60)
 * Bulgaria - 1 spur (I-20)
 * Hungary - 1 spur (I-81), 1 loop (I-64)
 * * Italy - 2 loops (I-55)
 * Portugal - 1 loop (I-1)
 * Romania - 2 loops (I-60)
 * * Spain - 2 spurs (I-9, I-20), 2 loops (I-10, I-610)
 * Switzerland - 1 loop (I-28)
 * Sweden - 1 loop (I-89)

Alternate Routes
On February 7, 2022, FDOT and SwissDOT has planned to add another type of highway called the "Alternate Interstate Highway". They will be signed with the word "ALTERNATE" as it replaces the "INTERSTATE" word above the Interstate Shield. There will be a loop, and a spur route. The shield will be the same, but completely red.

At this moment, there are four Alternate Interstates to be added:
 * I-28 Alternate Spur (I-20 in Lyon, France - I-28 in Geneva, Switzerland)
 * I-35 Alternate Loop (I-35/I-40/I-740 in Massy, France to I-35 in Attainville, France)
 * I-50 Alternate Loop (I-50/I-128 in Pratteln, Switzerland to Birrhard, Switzerland)
 * I-90 Alternate Loop (I-17/I-78/I-90 in Beuzeville, France to I-90 in Yvetot, France)
