In the event that circumstances alter the highway requirements

after the Director has acquired property so that it or a portion

thereof is no longer needed for highway purposes, the Director is

authorized to sell the real property involved or any portion thereof

in the name of the state on the relation of the Director, and shall

make deposit of the proceeds of such sale in the Highway Advance

funds have been contributed by municipal or county governments for

the purchase of such property, such funds shall be returned to said

municipal or county government together with any interest which such

contributions have actually earned.
