It enters Tajimi City, Gifu Prefecture, at the Utsutsu Pass which is about 250m above sea level.

Gifu Prefecture
It enters the urban area of Tajimi City around the point where it crosses the JR Taita Line at the Ikeda Overpass. It intersects with National Route 248 at the Otowa-cho intersection. This intersection is a chronic cause of traffic congestion. It passes under the elevated tracks of the JR Chuo Line, crosses the Toki River at the Kokei-Ōhashi Bridge, and then enters Toki City. It crosses the Shinmei Pass, passes under the Tokai-Kanjo Expressway, crosses the Toki River again at the Toki-Ōhashi Bridge, and enters the urban area of Toki City. It merges with National Route 21 at the Ōtomi intersection, and National Route 21 overlaps with it until its origin at the Yamanouchi intersection in Mizunami City. After the merge, It runs parallel to the JR Chuo Line until it enters the Mizunami Bypass. Immediately upon entering Mizunami City, there is the Yamanouchi intersection, where the old road (Gifu Prefectural Road Route 352 Ōnishi-Mizunami Line) branches off and the Mizunami Bypass begins. It crosses the JR Chuo Line via an elevated bridge, and then crosses the Toki River yet again via the Oda-Ōhashi Bridge. The bypass makes a large detour south through the urban area of Mizunami City. It crosses the Toki River and the JR Chuo Line at the Kōno-Ōhashi Bridge, and reaches the Tsurushiro intersection. This is the point where it merges with the old road and the end of the Mizunami Bypass. It narrows to one lane in each direction, and after passing through the Kamado-cho area of Mizunami City, it enters Ena City. This is the Takenami-cho area, and it intersects with National Route 418 at the Mukainagare intersection. It passes above the Shin-Makigane Tunnel on the downbound line of the JR Chuo Line, and a little later above the Makigane Tunnel on the upbound line of JR Chuo Line. It enters Ena Bypass just before reaching the urban area of Ena City. It intersects with Gifu Prefectural Road Route 66 at the Nagata Interchange, and when it reaches almost the halfway point of the bypass, it widens to two lanes in each direction. It merges with National Route 257 coming from the south at the Shōge intersection, and crosses the Agigawa River, a tributary of the Kiso River, at the Ena-Ōhashi Bridge. It passes under the elevated tracks of the Akechi Railway and merges with the old road (the end of the Ena Bypass). After that, it immediately passes under the Chuo Expressway and runs parallel to it until the Nakatsugawa Interchange. After passing the entrance and exit to Nakatsugawa Interchange, National Route 257 branches off to the north. It enters the Nakatsugawa Bypass here, and about 1.5 km further on, it crosses the Nakatsugawa River, a tributary of the Kiso River, via the Nakatsugawa-Ōhashi Bridge. It intersects with Registro Street (Gifu Prefectural Road Route 71 Nakatsugawa Sta. Line), which extends from Nakatsugawa Station on the JR Chuo Line, via an overpass. The Nakatsugawa Bypass ends at the Okita intersection, approximately 3km ahead, and narrows to one lane in each direction.
