Østerdalen (Urban East Norwegian: [ˈœ̂sːtəˌɖɑːɳ]) is a valley and traditional district in Innlandet county, in Eastern Norway. This area typically is described as the large Glåma river valley as well as all its tributary valleys. Østerdalen is often subdivided into Nord-Østerdal in the north, and Sør-Østerdal in the south. The more mountainous northern half of Østerdalen includes the municipalities of Rendalen, Alvdal, Folldal, Tynset, Tolga, and Os. The more forested southern half includes the municipalities of Elverum (which includes district's largest town, Elverum), Stor-Elvdal, Engerdal, Trysil and Åmot. Østerdalen historically also included Särna and Idre, which is now in Sweden.

👉 Østerdalen in the context of Gudbrandsdal
Gudbrandsdalen (Urban East Norwegian: [ˈɡʉ̂ː(d)brɑnsˌdɑːɳ]; English: Gudbrand Valley) is a valley and traditional district in the Norwegian county of Innlandet (formerly Oppland county). The valley is oriented in a north-westerly direction from Lillehammer and the lake of Mjøsa, extending 230 kilometers (140 mi) toward the Romsdalen valley. The river Gudbrandsdalslågen (Lågen) flows through the valley, starting from the lake Lesjaskogsvatnet and ending at the lake Mjøsa. The Otta river which flows through Otta valley is a major tributary to the main river Lågen. The valleys of the tributary rivers such as Otta and Gausa (Gausdal) are usually regarded as part of Gudbrandsdalen. The total area of the valley is calculated from the areas of the related municipalities. Gudbrandsdalen is the main valley in a web of smaller valleys. On the western (right hand) side there are long adjacent valleys: Ottadalen stretches 100 kilometers (62 mi) from Otta village, Gausdal some 50 kilometers (31 mi) from Lillehammer and Heidal some 40 kilometers (25 mi) from Sjoa. Gudbrandsdalen runs between the major mountain ranges of Norway including Jotunheimen and Dovrefjell–Rondane.
Together with the Glomma river and the Østerdalen valley, the river Lågen and the Gudbrandsdalen valley form Norway's largest drainage system covering major parts of Eastern Norway. Gudbrandsdalen is home to Dovre Line railway and the European route E6 highway. The valley is the main land transport corridor through Eastern Norway, from Oslo and central eastern lowlands to Trondheim and Møre og Romsdal.

Østerdalen in the context of Hedmarken
Hedmarken (Urban East Norwegian: [ˈhêːdmɑrkn̩], locally [ˈhɛ̂mɑrkɑ]; known as Hedemarken [ˈhêːdəmɑrkn̩] until 2003) is a traditional district in Innlandet county in Eastern Norway.
Hedmarken consists of the municipalities Stange, Hamar, Løten, and Ringsaker. In the past, it also contained the former municipalities of Romedal, Vang, Furnes, and Nes, but those municipalities were merged into Hamar, Stange, and Ringsaker during the 20th century. Traditionally, it also included Gjøvik Municipality on the other side of the lake, but this is no longer the case. The old county of Hedmark was named after the district of Hedmarken, but the county included several other districts as well, namely Østerdalen and Glåmdalen (Solør, Odalen and Vinger).
Østerdalen in the context of Rørosbanen
The Røros Line (Norwegian: Rørosbanen) is a 383-kilometer (238 mi) railway line which runs through the districts of Hedmarken, Østerdalen, and Gauldalen in Innlandet and Trøndelag, Norway. The line branches off from the Dovre Line at Hamar Station and runs a more easterly route to Støren Station, where the two lines meet again. The Røros Line also intersects with the Solør Line at Elverum Station. The single track, standard gauge line lacks electrification and only has centralized traffic control south of Røros Station. SJ Norge operate regional passenger trains. In addition the line is used by freight trains hauling lumber and wood chippings.
The first parts of the line was the Hamar–Grundset Line and the Trondhjem–Støren Line, which opened on 23 June 1862 and 5 August 1964, respectively. To save costs, the lines were built with narrow gauge, thus making it the first locomotive-hauled 1,067 mm (3 ft 6 in) line in Norway. The Grundset–Aamot Line extension to Rena Station was opened on 19 October 1871. The connecting line onwards to Støren opened on 13 October 1877. The 1880 completion of the Dovre Line to Hamar allowed a continuous train service linking Oslo and Trondheim, albeit with a break-of-gauge in Hamar.
Østerdalen in the context of Norwegian National Road 3
Norwegian National Road 3 (Norwegian: Riksvei 3, Rv3) is a Norwegian national road that is the main route through the Østerdalen district in Eastern Norway. It has been dubbed Den grønne Snarvei which means 'the green shortcut' by the old Hedmark County Municipality. The route runs south from European Route E6 at Ulsberg in Rennebu Municipality in Trøndelag county, via Tynset and Elverum, to Stange in Innlandet county, where it rejoins European Route E6. The route was 291.3 kilometers (181.0 mi) long, of which 277.9 kilometers (172.7 mi) are in Innlandet county and 13.4 kilometers (8.3 mi) are in Trøndelag county.
National Road 3 is the route most used for transport between Oslo and Trondheim, carrying approximately 90% of heavy traffic and most of the passenger car traffic between the two cities. This is because the route is about 42 kilometers (26 mi) shorter in comparison to European Route E6, has better curvature, goes through fewer towns, and has smaller grades. Unlike the E6 over the Dovrefjell mountain range, National Road 3 is also never closed due to winter weather. There have therefore been proposals to reroute the E6 to Østerdalen (along the route of National Road 3). This is however not the official plan. Big money is spent to upgrade about 100 kilometres (62 mi) of E6 (Øyer–Stange) to four-lane motorway and upgrade of long other parts of E6. Much less is spent on Road 3, although 14 kilometres (8.7 mi) of four-lane motorway was opened in 2020, but not much more investment is planned.
