text: I-35 ramp from SH-51 near Stillwater narrowed through 2019
  
  The westbound SH-51 ramp to southbound I-35 and the merge area onto southbound I-35 are narrowed to one lane for bridge repairs through 2019. Westbound SH-51 traffic can still take the ramp to southbound I-35 but should use additional caution as the merge area is narrowed and expect delays during peak travel times. Drivers should begin considering alternate routes leaving Oklahoma State University football games this fall.
