The stretch is part of an important national goods corridor in the north-south direction. National road 3 through Østerdalen is the route alternative that has 80-90% of the heavy transport that goes on the road between Oslo and Trondheim. On national road 3 through Østerdalen, the main challenge is the road width and curvature, which are extra problematic as regards accidents and accessibility. In the National Transport Plan period 2018-2029, Evenstad – Imsroa has been one of several sub-stretches that are prioritised for improvement along national road 3.

The project includes alterations to national road 3 and improvements to the existing dual carriageway between Evenstad Bridge and Svingen, and a road along a new route to the east of the current road between Svingen and the junction with Birkebeinerveien to the south of Imsroa. The length of the improvement to the existing road is approx. 0.5 km and the construction of a new road approx. 5.0 km.

Three T-junctions are to be established on the stretch, two junctions with a left turn lane, and one junction with a passing lane.

The current road will, together with the old national road route Innatilveien in the south, be maintained as a local road and offer for pedestrians and cyclists. These roads are to be improved in accordance with D2-10, D2-20, and D2-71 NA-circular letter 97/13, guidelines for technical requirements for roads that are to be reclassified - commencement of the Road Act §7.

The project also includes the establishment of matter removal at Rogner for uncompacted matter and commissioning a borrow pit after the removal has finished.
