East Bose Highway (商業都市) is a road that connects the City of Bose with other locations in The Legend of Heroes: Trails in the Sky. It is often traveled upon from travellers coming from the Verte Bridge from Rolent.
The road is travelled upon when Estelle, Joshua, and Scherazard first reach the Bose region from Verte Bridge. They used the road to get into the City of Bose. Later, they used the road to get into the Haken Gate as well.
The road is set in between the City of Bose to the west, Eisen Road to the Northwest, Nebel Valley to the northeast, and Verte Bridge to the east. If the player chooses to do some bracer missions then the road will be backtracked many times.
No treasure chests in the area.
