Other portions of I-35 that will see a speed increase include I-35 from the Texas border to near Purcell,I-40 will see different areas where the speed limit will be raised. This includes I-40 from the Texas border to near Elk City, just east of Elk City to just west of Clinton, just east of Weatherford to near Yukon and Shawnee to Sallisaw.Speed limits in urban areas will remain the same. Speed limit changes won’t be effective until new speed limit signs are manufactured and posted. The process could take around 2 months. In the meantime, the lower posted speed limits will continue to be enforced.The vote on Monday was similar to an action one week ago when the Oklahoma Turnpike Authority voted to increase the speed on sections of rural turnpikes in Oklahoma.
