text: I-40 and SH-6 narrow in Elk City for bridge project
  East- and westbound I-40 will be intermittently narrowed to one lane for each direction at SH-6 in Elk City through mid-2020. Additionally, north- and southbound SH-6 is narrowed to one lane for each direction at I-40 as part of an ongoing one-year bridge replacement and interchange update project.
  
  I-40 will have minimal off-ramp closures. I-40 on-ramps will be closed intermittently. Minimal night-time, full closures of I-40 and SH-6 will occur to allow for demolition of the existing bridges in fall 2019. During the full I-40 closures, traffic will be directed onto the ramps then back on to the interstate for through travel.
  
  Motorists should plan for delays, and expect lane shifts on I-40 and SH-6. The speed limit will be reduced in the work zone and motorists are advised to watch for workers and equipment entering and exiting the road in the construction zone.
  
  The $16 million project was awarded to Frontier Bridge Inc. of Okarche and includes the following:
  
  Reconstruction of the SH-6 bridges over I-40, which are structurally deficient;
  Construction of the state’s first Diverging Diamond Interchange;
  Reconstruction of the SH-6 and I-40 on- and off-ramps; and
  New traffic signals at the ramps and aesthetic elements in partnership with the City of Elk City.
  The project began in May 2019 and is expected to complete in one year, weather permitting.
