Ohio State Route 257

State Route 257 (SR 257, OH 257) is a 26.19-mile (42.15 km) north–south state highway in the central portion of the U.S. state of Ohio. The highway's southern terminus is in the northwestern Columbus suburb of Dublin at a signalized intersection with U.S. Route 33 (US 33) and SR 161. SR 257 has its northern terminus at a T-intersection with SR 47 on the western village limits of Prospect.

SR 257 was created in the middle of the 1920s. This mainly two-lane highway follows the eastern side of the Scioto River from Dublin to its junction with US 42. After crossing over the river with the U.S. highway, SR 257 then parallels the river to the west up to Prospect.

Route description

Along its way, SR 257 travels through northwestern Franklin County, western Delaware County and the extreme southern part of Marion County. There are no segments of SR 257 that are included within the National Highway System (NHS). The NHS is a network of highways identified as being most important for the economy, mobility and defense of the nation.^[6]

History

The SR 257 designation was applied in 1926. Originally, the highway was routed along its present southernmost alignment along the eastern banks of the Scioto River between Dublin and its northeastern junction with US 42.^[1][2]

In 1935, SR 257 was extended via a short concurrency with US 42 across the Scioto River, then north along its present alignment along the western side of the river to a new northern terminus at SR 37 west of Delaware.^[7][8] Then, two years after its first northward extension, SR 257 was extended to the north again, this time to its present northern terminus at SR 47 in Prospect.^[9][10]

SR 257 was designated the General Thaddeus Kosciusko Memorial Highway in 1975.^[11]
