Transportation

Dayton is served by three signed Oregon state highways and one unsigned state highway:

• Signed highways
  • Oregon Route 18
  • Oregon Route 221
  • Oregon Route 233, which travels as one road with State Route 18 between Lafayette Highway to the west and Oregon Route 99W to the east.
• Unsigned highway
  • Oregon Route 154 (SE Lafayette Highway) is assigned this route number south of its intersection with State Highway 233.

Prior to the construction of Highway 18 as a limited-access bypass of Dayton and McMinnville, Highway 233 continued east on its old route (SE Amity-Dayton Highway) into downtown Dayton, where it was named Ferry Street. The highway crossed the Yamhill River via ferry to the northeast side of the river at what is now called Alderman Park. There, Highway 233 continued northeast along SE Kreder Road to its northern terminus at what was then numbered as US Route 99W. During this period, the northern terminus of Highway 221 was located at its intersection with Ferry Street.
