 Initial turnpike plans included environmental mitigation features to reduce the amount of disruption the finished road would cause to the local environment . In the Jenks area , OTA planned to replace destroyed wetlands with new wetlands of equal or greater size . <unk> were expected to plant two trees for every one removed to build the road . In March 1990 , these plans were augmented to provide wetlands mitigation at a rate of three to one , for a total of 45 acres ( 18 ha ) of new wetlands . Additionally , 25 acres ( 10 ha ) of pasture would be allowed to revert to its natural state to create " dedicated natural succession areas . "
