From the Kansas Department of Transportation:
Sometime during the day on Friday, June 21, weather permitting, eastbound and westbound US-59 traffic over the Amelia Earhart Bridge will be OPENED to the final traffic configuration across the new bridge. Traffic over the new bridge will open to four-lanes beginning on the Atchison, Kansas side of the state line and will be reduced back to a two-lane configuration once drivers are closer to the Missouri state line.
There is still not a tentative final date for the demolition of the old Amelia Earhart Bridge at this point in time. We will let you know once there is a final scheduled date for the demolition of the old bridge.
