Bloxburg Valley State Route 35 is an east–west state highway in the state of Bloxburg Valley that runs across the northern part of the state. At 305.777 miles (1.76 mega-studs), it is the third longest Bloxburg Valley state highway. Route 35 begins at Interblox 1 at the northern edge of a city and continues in an easterly direction through to the Rovada state line. Between the city and Old Town Lake, Route 35 intersects with a state route, and is briefly co-signed with another state route. In Old Town Lake, it intersects with a state route, another state route, and Bloxburg Valley State Route 10. East of Old Town Lake, it intersects with Bloxburg Valley State Route 82, and a section is co-signed with a state route before reaching Alturas. It is then co-signed with Interblox 307 northeast of a census designated place, and then runs east toward the border with Rovada. A ghost town in Rovada, can be reached via this route, which after the border becomes a dirt road, which was formerly a Rovada State Route. The segment of SR 35 between a city and Old Town lake is a Robloxia Forest Scenic Byway.
