Old route In the 1938 road numbering system, main road 58 was the road between
Lahti and
Padasjoki, but after the completion of the
Helsinki–Lahti road,
national road 4 was rerouted to run through Lahti and road number 58 was dropped.
Current route The road between Orivesi and Keuruu began to be built in the 1960s and was completed at the turn of the 1960s and 1970s. The Orivesi–Mänttä section, which was built from 1961, was opened in November 1966, despite being unfinished. This was numbered as regional road 341 upon completion, and was upgraded to a main road in 1977 and numbered as main road 58, restoring the number. In the 1996 renumbering, the section from Keuruu to Karstula became part of main road 58, replacing regional roads 622 and 634. The sections between Kangasala and Orivesi (former regional road 324) and Karstula and Kärsämäki (former regional roads 646, 775, 751, 761 and 768) were renumbered a few years later. == Route ==
