The idea is to investigate the route in order to be able to develop measures that increase road safety and accessibility for all road users. Including unprotected road users and traveling by public transport.

- We have identified shortcomings and want to investigate further. It can be about changing speed limits, looking over intersection problems and looking at stops along the way, says Torbjörn Andersson, action planner at the Swedish Transport Administration.

The authority must at the same time review the maintenance of the road. The distance that applies is between Sala and Västerås, excluding the urban areas. Through Västerås, for example, the 56th has already been reviewed in conjunction with the E18 investigation.

The Swedish Transport Administration will also review whether it is possible to illuminate the crossings of the national road in the area at Romfartuna.
