  I-35/US-70 West/SH-199 ramp changes in Ardmore
   
  I-35 also remains narrowed to one lane in each direction at the US-70 West/SH-199 interchange (Exit 31).
   
  The following ramps at the I-35 interchange at US-70 West/SH-199 are now open to traffic:
  ·       Southbound I-35 off-ramp to US-70 West
  ·       Southbound I-35 off-ramp to SH-199 East
   
  The following ramps at the I-35 interchange at US-70 West/SH-199 remain closed through June for ongoing bridge rehabilitation:
  ·       Northbound I-35 on-ramp from westbound SH-199
  ·       Northbound I-35 on-ramp from eastbound SH-199
   
  Drivers are urged to be alert and follow detour signs for safety. Drivers can expect congestion and should plan for extra travel time in this corridor, especially during weekends and holidays. I-35 travelers can use SH-142 (north of the work zone) or US-70E (south of the work zone) to minimize delays.   
  
  The first phase of this project to rehabilitate the I-35 bridges over US-70 West and the BNSF railroad was completed in fall 2015. The final phases will require additional lane closures in late 2016. 
  
  The nearly $8 million contract for this project was awarded to Overland Corporation of Ardmore in February 2015.
